DECEMBER INVISIBLE FLOWERS

Yesterday Ed’s brother, Bob, joined us for our weekly nature walk. We headed for Saguaro National Park East, taking the Cactus Forest trail to Lime Kilns and Lime Falls. The night time temperature was in the low forties, but during the day, rose to a comfortable 70.

I went to take a picture of a beautiful group of Christmas cactus with their bright red fruits, and found that the camera’s battery needed recharging. This meant that I had to see through my own eyes, and not so much the lens of the camera. At this time of the year, the second week in December, we did not expect to see many flowers in bloom. At first we noticed some tobacco plants with flowers, plus lots of paperflower plants in bloom.

Desert Tobacco (Nicotiana obtusifolia)

Whitestem paperflower (Psilostrophe cooperi)

By the time we had finished, we counted 19 flowering species, and 8 of them were invisible! By “invisible” I mean walking past them most people would not even realize that they were in bloom. And here they are close up.

Fittingly, I suppose, I have been unable to insert pictures here, so some of them will remain invisible. anyway, here are the names:

Slimleaf bursage (Ambrosia confertiflora)

Parry dalea (Marina parryi)

Earleaf brickelbush (Brickellia amplexicaulis)

Pictures of the other five have been shown in this blog before, and here they are:

The Night blooming cereus is an inconspicuous plant except on those rare nights when it blooms, or when it is in fruit. Ed spotted one with a bright red fruit about the size of a hen’s egg. Without the fruit we would never have noticed it.

This was one of those special days, hiking with friends in perfect weather surrounded by the richness of the Sonoran Desert.

AMAZING INVISIBLE FLOWERS

Ed and I were walking along the dirt road at the top of the Ski area in the Catalina Mountains. We found over 40 species of flowers in bloom, including a few mysteries. At the spot where we saw some unusual plants last year, we found a California poppy in bloom, and Bachelor’s button, plus a beautiful, tiny blue flower, at the top of about a four inch stem.

We had more or less ignored the Dock plants that covered large sections of the ground (Rumex species), thinking they were the usual Curly Dock (Rumex crispus) or Bitter Dock (Rumex obtusifolius), but then I stopped to look more closely. This was the rarer Pale Dock (Rumex altissimus). “Altissimus” means very high and we were about 9000 feet above sea level. We thought, too bad it is not in bloom. We sat down, the plants now higher than our heads. The flower stalks were a rusty red color. After a few minutes we decided to get out our trusty magnifying lenses, and soon found that the plants had flowers and fruit! These certainly qualified as “invisible” flowers, invisible to us until we took a closer look.

The next day Andrea in our group, came across an orchid that I had known existed on the mountain but had never seen. I just got this one photograph. It is called Slender-flowered malaxis (Malaxis abieticola). The plant itself is about six inches tall. Two days later Patrick and Tori looked for the orchid but it was gone, possibly eaten. I am glad I got at least one good picture.

AND THE RAINS CAME

The rains have come, and the mountains are springing back to life. For some plants the rains came too late, as you can see in this Bracken fern (Pteridium aquilinum). We saw a patch of them that had already turned brown as if calling it quits for the year. Fortunately most of the ferns have survived.

And there are wild flowers everywhere!

On a recent hike we found ourselves studying the fallen trees and noticing that the logs had yellow highlights. It seems as if there is a fungus, also responding to the rain, that attacks only certain parts of the fallen trees. The yellow spots are knot holes, remnants of branches when the tree was very much younger.

On my recent trip Ellen told me about a grass in bloom, Squirreltail grass (Elymus elymoides). I took some photographs, then noticed in my grass books that the awns on the head of the grass splay out. I took a piece home with me. Within a few hours it had opened up into this wonderful form.

Today I went looking for more grasses but got distracted by coming across Desert spoon plants (Dasylirion wheeleri or Sotol), with the flowers within reach. We have one in our front yard. The flower stalk is over 10 feet tall, and half of that is covered with male flowers. This is one of those plants that has separate male and female plants (dioecious). I have been wanting to use my close up lens to see what the actual flowers looked like, and today was my day. I found many plants in Molino Basin. some of each sex with flowers near enough to the ground to be reached. After blooming the stalks stay on the plant for over a year.

GETTING CLOSER

Last week a group of us were having lunch after a nature walk. Many of the people in the group were keen bird watchers, so you can imagine their astonishment when they heard the call of an owl in the middle of the day. One woman wanted to see the owl, so she went to investigate. Minutes later she returned, a little bit deflated. “It wasn’t an owl” she explained, “just another bird watcher making owl sounds.” I found out later that some little birds will gang up on an owl to drive it away. By making owl sounds the person was trying to trick some of these little fellows into emerging from the shrubs. I don’t know if he (or she) fooled the little birds. It fooled us.

Today we saw a few birds but I was more interested in getting a close up view of two plants I have known for some time – Bear Grass and False Indigo.
Nolina microcarpa
Bear Grass (Nolina microcarpa) is not a grass at all, but a very large plant in the Asparagus family. In May the plants send up a flowering shoot, four feet or more tall. The species is dioecious, meaning that male and female flowers are on separate plants. Whereas the flowering stalk is huge, the flowers are quite small, and we were having some difficulty telling which was the male and which the female. Eventually we found some with tiny little flowers clustered on the long stalk. I was able to get a close up of the flowers, and finally can tell the two apart.

This is a watercolor portrait I did of Bear Grass

Later we came across a clusters of False Indigo plants – Amorpha fruticosa. From a distance it is hard to tell if the plant is in bloom or not. Up close, you can see the flower stalks, with the bright yellow anthers emerging from a deep purple base. I had never been able to photograph the individual flowers before today. I was thrilled to see what they look like. The genus name, amorphous, means “deformed” referring to the fact that each flower doesn’t have the usual form with a number of petals. It just has a single one curled around, with the anthers protruding from it.

On the home front, I have been watching the golden barrel cactus in our front yard. A few months ago I noticed that one of them was looking a little sickly. On closer inspection I found that I could see right through it in places. Our property is home to many ground squirrels, and I think they found a way of getting to the fleshy interior of the cactus. On the outside, the plants are well defended. Coming from underground, the ground squirrels found the soft underbelly, and have almost completely hollowed the plant out. They did the same to one of the other two. And yet all three cactus plants are still alive! They are gutted, but not totally defeated.

MAKING VISIBLE THE INVISIBLE

February has been a month full of interest.   More and more plant species are coming into bloom. I had the pleasure of speaking twice – the first in Sierra Vista to the Cochise Chapter of the Arizona Native Plant Society (AZNPS) on “Invisible Flowers and Other Wonders” , and two days later giving a similar speech to the Arizona Botany Meeting 2014, at the Arizona-Sonora Desert Museum,  “Taking a Closer Look.”  Both talks gave me a chance to share pictures I have taken, some looking at familiar flowers close up, others showing “invisible flowers”, flowers that are so small or insignificant that people walk by them not knowing that they are in bloom. People responded very favorably to the two talks.
At the conference I had the pleasure of making contact with people who share a love of plants, and all things in nature. The day ended with a dinner, and a speech by local raconteur Petey Mesquite, whose radio talks have entertained people for years. He proved to be a most engaging speaker with his stories, pictures and songs. What a delightful way to end the day!

The next day there were optional nature walks. I went on the one led by Jim Verrier. There were about 15 to 17 people on the hike, including some specializing in certain aspects of botany, like sedges and rushes.  Everyone had something to contribute to the richness of our experience, and we all shared the love of discovery.

Several times our group gathered around an apparently bare patch of earth, some of us on all fours. People gave us strange looks as they walked by in bewilderment. We were definitely looking at things that they were not seeing.

We found some interesting “invisible” plants, including Mouse-tail (Myosurus cupulatus, in the Ranunculus family). This is a very small plant that grows in wet places in the early spring. I have looked for it in Molino Basin and Gordon Hirayabashi this year without success. Evidently it is too dry there. But we were in Catalina State Park, where there is some water still flowing even though it has not rained much in the last eight weeks. Another small plant is Miner’s lettuce (Claytonia perfoliata), so called because it is an edible little plant and its stems are perfoliate, going right through the center of the leaves. The tiny white flowers come out of the top leaf like a miniature lotus in its lily pad.

We had two very special plant people on the walk, our leader,  Jim Verrier and one of Arizona’s most knowledgeable botanists, Richard Felger. Each of the other people on the hike brought some special knowledge of nature, which made for a very rich and enlightening experience.

We came across just a few examples of another plant that I met in Catalina State Park last year and regretted not finding it with flowers or fruit (Common pussy paws, Cistanthe monandra).  Also last year I did not have my super macro lens. We found that the plant was mostly in fruit, but Richard Felger pointed out that there were some very tiny flowers. Its species name  “monandra” which means “having only one anther”, which you can see in the picture.

CLOSE UP NATURE PICTURES

The last two days have taken me up into the mountains, a pleasant break from the freezing temperatures in Glenview, north of Chicago, where my wife and I spent last week end.
Ed and I walked in the Gordon Hirayabashi camp ground. As soon as we parked the car we noticed a plant that looked, from a distance, like a bladderpod, though we knew that it does not normally grow at this elevation. On closer look the “flowers” were actually leaves. Looking still closer we saw that these leaves at the tips of the branches were covered with yellow papillae. We have no idea what the plant is. From the woody stem, we decided it must be a perennial. We will enjoy checking on it from time to time to see how it develops.

We had almost given up on seeing any flowers on our return journey when we heard a loud buzzing coming from the top of some of the cottonwood trees. These were the male trees, with their golden catkins. Some of the trees still had leaves left over from last fall. All of them had leaf buds developing at the end of the twigs.
We stopped for a snack by a little waterfall. It was actually running, though very slowly. We have had precious little rain this winter. There we noticed that the Alligator juniper (Juniperus deppeana) was coming into flower. They are not true flowers, but thousands of little brown buds containing pollen. They are called pollen cones. I managed to get a close-up of one of them, and also of new fruit forming. It is red now but will turn blue as it ripens.

The next day Dave and I went to Bear Canyon and found that the great Arizona cypress trees (Cupressus arizonica) were also coming into flower. I managed to get a close up of the pollen cones, including some that evidently had finished releasing their pollen. Then for the first time Dave found what seems to be a seed cone (the female part of the plant.) Cypress FLm

Dropping down into the canyon we came across a large dried up plant which we think was a Pokeberry (Phytolacca icosandra). It had lots of last year’s fruit on it. The ones on the tips of the branches were deep red. Lower down they were grey and white. I love the close-up pictures we were able to get.

We also saw lots of willow in bloom, possibly Coyote willow (Salix exigua). It seemed much too early in the year, but the bees certainly knew that it was in flower. This is another dioecious plant. With my new close-up camera I was not only able to look more deeply at the male flowers, but for the first time, saw the actual flowers on the female shrubs. They are the tiny pale yellow endings to the green spikes.

MILE HIGH BEAUTIES

Yesterday Dave and I felt we needed to get out in the fresh air. I had been cooped up with a cold for over a week, and Dave had been busy. We both needed the renewal that we always find in the mountains.

We did not have much time, so we drove just over seven miles up the mountain road and headed toward Bug Spring. Then we looked up at the peak straight ahead of us and felt it calling. A deer trail took us to the top. We were just about a mile above sea-level, commanding a beautiful view of the valley. We could see part of Tucson, and distant mountain ranges. The temperature was mild. It was the middle of January, so we did not expect to see any flowers, but there they were, smiling bravely at us. We even found a beautiful pool in the stream bed, complete with a floating white butterfly. We saw a few live butterflies and even heard the rush of a humming bird, but never saw it.

NOSE BURN

The forecast yesterday included high winds and a chance of rain. Ed and I set off for Saguaro National Park East and the Cactus Forest Trail. We walked past the old lime kilns, came to a junction in the trail and decided to head for Lime Falls. The trail in part follows a stream bed. There were even a few little pools of water left over from rain last week. As we walked I told Ed about my new interest in Spurges – members of the Euphorbia family. It is a very large family with 300 genera and about 7,500 species. Many of them have “invisible” flowers as I have noted in this blog before. Probably the most famous, especially this time of year, is Poinsettia (Euphorbia pulcherrima). Poinsettia flowers are very small, hidden in the center of the top leaves. The leaves are the showy part and may be red or a variety of other colors.
I told Ed that I had even thought of buying a book about this family, but learned that the one that seemed the most interesting costs about $500 (in a ten-volume set). It is definitely a fascinating family, but maybe not worth that much to me right now. Just then I looked down in the stream bed and saw a rather dark plant. Some of its leave had turned red. I knew at once it was Nose burn (Tragia nepetifolia), so called because its leaves irritate the skin. Until today I had never dared to pick the plant or inspect the flowers at close range. It seemed to both of us that it was not in bloom. A few days ago I had looked for flowers on this plant in Molino Basin and concluded that it was long past blooming, so I assumed that this one was no longer in flower. But then, realizing that we were dealing with an “invisible” flower, I leaned down, and inspected it with my loupe. To my delight it was in full and glorious bloom. I picked a sprig, not worrying at all about its stinging reputation. It was not very irritating after all. Here are the pictures I took of this fascinating plant.

We met a couple on the trail, and after a brief conversation realized that we had met them before much higher up on the mountain – an area called Bear Wallow. They were Rick and Pat, and were very much interested in all aspects of nature, so we introduced them to this “invisible” flower and invited them to join the blog so that they could see these pictures.

It was a very pleasant day in the desert. We even saw other plants in bloom, including a Brittle bush, Wire lettuce, Dalea (pulchra, we think), and now this Nose burn.

When I woke up this morning there were three tenths of an inch in the rain gauge, so the rain did come, and very welcome it is.

A GLORIOUS MOUNTAIN HIKE

A few days ago I went to Arizona Lithographers and picked up their 2014 calendar. I knew that they included one of my paintings in the calender, but wanted to see it in print. This is part of the back of the calendar with  a portion of the August page from a painting I did of Seven Falls in the Catalina Mountains (the painting on the right in the middle row).

Yesterday Ed and I decided to revisit a trail I have hiked many times. It is a section of the Arizona Trail (a trail that goes from Mexico to Utah, a total of about 800 miles.) We drove to Molino Basin in the Catalina Mountains, and set off across the road and toward the east. It was cool with light breezes. This late in November we did not expect to see anything in bloom, but right away we saw several camphorweed plants with a few blooms (Heterotheca subaxillaris). Then one lone wire lettuce (Stephanomeria sp.), and several turpentine bushes (Ericameria laricifolia) loaded with flowers.

Turpentine bush

 

 

The leaves of the Turpentine bush smell like – you guessed it – turpentine.

 

 

 

 
It took us a while to realize that there was another plant in full and glorious bloom, one of my “invisible” flowers. We were not sure of the exact species, but it is one of the euphorbias, possibly Spurge (Euphorbia pediculifera). The plant was very dry and somewhat shriveled, and it was not until we got home that I could see that it was really in bloom. In fact it was loaded with blossoms, each one very minute.

The hillside we climbed is covered with shin daggers (Agave schottii). There were no flowers, but plenty of flower stalks, and some of them sported little baby agaves – pups – plants that were starting to form on the mother ready to drop to the ground and assert their independence. Neither of us had ever noticed shin daggers sprouting babies like this before, though we had seen other agaves that have this skill.
Bellota view
Our turn-around point afforded us a view to the south of Agua caliente hill, and behind it the Rincon mountains. It was a truly gorgeous day, and another delightful hike.

BUCKWHEATS

Many times I find nature overwhelming in its complexity and beauty. It is impossible to know everything about everything. Over time I have learned that it is enough to get to know some things about a few things in a fairly limited area. Which brings me to buckwheat. I first got interested in buckwheat when I did illustrations for the first edition of Charlie Kane’s “Herbal Medicine of the American Southwest”, including paintings of flat-top buckwheat (p. 98-100). Now, eight years later, I decided to take a closer look at the buckwheat flowers.

With my new camera and lens I can zoom in and see flowers at a much closer range than before, and discover things I have not yet noticed.

The buckwheat family is called Polygonaceae, from the Greek word polygon = knee, referring to the fact that many in this genus have thickened joints on their stems.

The genus is eriogonum, from two Greek words: erion=hairy or woolly, and gonu=joint, since some species in this genus have hairy joints.

How many Eriogonum species are there?
240 – in the world (Wikipedia)
200 – in the United States ( Kane)
100 – in Southern California, Arizona and New Mexico (Ricketts)
50 – in Arizona (Epple)
5 – in the Santa Catalina mountains above 4000′ (Verrier and Tedford)

Of these five, let me show you two, one visible and the other “invisible”.

The visible one is Flat-topped buckwheat or eriogonum fasciculatum. The botanical name refers to the fact that the leaves are in fascicles, or bundles where they attach to the stem.

Here we see a road cut in the Catalina Mountains with eriogonum fasciculatum in fairly large clumps all along the slope.  Eriogonum fasciculatum1pass
Eriogonum fasciculatum1
These large masses look almost black in the late fall and winter. Then, in the early spring, they turn a beautiful green and soon are topped with a bouquet of pale pink flowers.  After a while, as the flowers fade, the top turns a pleasant rust color.

 

 

Here we see a group of plants, with just a few flowers left.

The second species is one of the “invisible” buckwheats,  – Sorrel eriogonum,  eriogonum polycladon (meaning having many branches).

Eriogonum polycladon3

The plants are about two feet tall. You can see the way they branch. The pinkish-white parts at the end of the stems are the flowers. There are fields full of these plants between 4000′ and 5000′. Often I have walked by them and wondered if they were in bloom or not, since the flowers are so small. The stems are grey. The flower buds are partly red and the flowers mostly white. From a distance these plants give a beautiful pink glow to the landscape.
