Since I decided to photograph grasses I have made several trips up the mountains. Most of the species have finished blooming for the year and are loaded with seeds. I love seeing the many forms that these grasses take. I can see it is going to be quite a challenge getting to know them all.

In my growing collection of plant books, there were none for the grasses, so I bought three to start to learn them. One was first published in 1899, another in 1935 and the third in 1979, so there may be some problems in name changes. All three have line drawings which are quite beautiful, but are not able to show the colors of the flowers, and the fine details of their fruits.

I realized that a better way of learning grasses is to see the plants themselves. It dawned on me that there is a huge collection of grasses, mounted and labeled at the University of Arizona Herbarium. So I took my camera and set off for the Campus. In the building that houses the herbarium I met many of my botanical friends and they helped me find the grasses I was looking for. In about four hours I photographed over 100 of them. A few days later I went to the collection put together by Joan Tedford at the Palisades ranger station in the Catalina Mountains, and photographed that collection (over 70 species). I am beginning to have a way of identifying the grasses I have been seeing and photographing. By the time Spring comes around I will be better equipped to name the different species as they come into bloom.

In my hikes I have found a few species in flower. It turns out that the showiest ones happen to be problem grasses that are crowding out the native species in certain areas. On one trip I found two of them side by side, both of which are a real problem in this part of the world. It turns out that they are related. (Pennisetum ciliare or Bufflegrass, and Pennisetum setaceum or Fountain Grass). You can see their similarities in these pictures. I found another non-native grass in beautiful bloom. It is not as much of a problem, and is an important food crop, Sorghum halpense or Johnsongrass.

I think I’m falling in love. No, not with Louise – well, yes, I did that in 1954. I mean I have a new love. I think I am in love with grasses.

For some reason I have been ignoring grasses these last 14 years. In that time I have learned to identify about 500 different wildflower species, and every tree species in these southern Arizona mountains, but grasses were a great, deep mystery. It seemed impossible for anyone to learn them. Because I hadn’t really looked at them, they looked all the same to me. And then my friend Jim suggested that I start photographing grasses. He would help with identification. Immediately I knew that this was going to be my next project.

I learned that there are fewer than 200 grass species in the Catalina mountains. (In one list I have there are fewer than 100). Surely I could get to know the grasses. I found one hiking with Ed in Turkey Run last week, and then went to Molino Basin a few days ago and found lots more. At this point I am not able to put names to any of them.

Last evening my wife and I decided to abandon the idiot box and go for a stroll in Molino Basin.
We left our house at 5pm.  We arrived at the parking lot at about 5:20. This was a half hour before sunset, but the sun was already obscured by the hill to the west, so we could walk without hats or sun screen. It was a beautiful evening, clear, light breeze, perfect temperature. We walked up the paved camp road – less than a mile. The roadside was lush with grasses. When we turned around I decided to see how many distinct grass forms I could see on the way back to the car. I was struck by the great variety and stunning beauty of the fruiting heads of these grasses. I was also struck by how easy they were to tell apart. I realize that this will not always be the case, but in the space of less than a half an hour I figured I had seen over thirty different species.

At one point Louise stopped me to point out a line of ants scurrying across the road carrying white bundles of some sort. . With my binoculars I could see that many of them were carrying grass seeds, like the beautiful one in this photograph.

And here is one of the grasses we found yesterday. The first picture shows a branch. The second moves in closer, and the third closer still.

There was heavy wind in the forecast today in southern Arizona so Ed encouraged me to bring a jacket. How right he was. We walked up Turkey Run, having rejected the idea of Oracle Ridge where the wind would have blown us off the mountain. Even in the deep woods it was very windy and there was a fall chill in the air. We did not see many wildflowers, about half as many as last week (14 compared to 37). We did see this beautiful Richardson’s geranium with two blooms on a single plant one white and the other deep pink. In this species the color can be blue, white or pink.

It turned out that the big attraction on this walk was not to be wildflowers but fall colors and clouds.

We arrived at our snack point. I sat on a log. Ed moved up the slope to look at a stand of trees including some Big Tooth Maple in full color. He stood there for the longest time, mesmerized by the view.

Eventually I joined him and saw what had held him spellbound. We stood there, looking up the hill with a stand of trees, many in their fall colors. Above the trees wonderful formations of clouds were moving swiftly up and over our heads. It felt as if the clouds were holding still and the world had suddenly accelerated its rotation.

This picture gives you some idea of the view of the trees and one of the many cloud forms racing above them.

Ed and I were on the return leg of our hike in Marshall Gulch in the Catalina Mountains today. We came across some flowers we had not seen on the outward journey, especially the beautiful blue Mountain Lobelia. 

I said: “Will wonders never cease?” and Ed replied: “That exact phrase has been running through my head for the last ten minutes.” I suggested that he might have planted it in my mind by some mental transference. At least it showed how much we were sharing a sense of happiness and wonder.

When we set out on the hike we expected that now, early in October, we might see some of the fall colors for which this part of the mountain is famous. We did not expect to see many flowers, not at 8000 feet. It proved to be the reverse. The fall colors were just barely starting. See this spray of big-tooth maple leaves.

And there were lots of flowers. We counted 25 on the outward journey and 12 more on the return. (See the list below)

At our turn-around point Ed noticed a plant across the stream bed. We paused, took out our binoculars, and realized that it was a collection of Spikenard plants (Aralia bicrenata). This is a plant that we have seen in only a few places on the mountain. And there, in their fall colors, was a family of at least a half a dozen plants. This photograph shows one of them.

We were surprised to see many Canadian violets. We noted one that had a lot of pink (they are usually pure white.) I also caught this picture of a seed pod that had recently burst open to fling out the seeds for the coming season.

On the way up the mountain we saw crews working in Bear Canyon, putting up barriers to the washrooms and picnic areas. My first thought was: “The shut down of the government has come to the Catalina Mountains.”  When we started the hike in Marshall Gulch the bathrooms were open, but when we returned it was clear that the crew had made it to the top of the mountain, as you can see from this photograph.

Fortunately all of the trails are still open, but the bathrooms, picnic table and Ranger station are closed until the government is allowed to get back to work.
