Portraits of Wildflowers

Two-leaf senna

with 18 comments

Here’s a native wildflower I’ve never shown you before. That’s surprising, given that it grows in my neighborhood and that on several occasions I’ve shown the other species of senna that grows here. This one is Senna roemeriana, known as two-leaf senna or two-leaved senna. The common name refers to the fact that each of the plant’s leaves is made up of two leaflets; you can see one leaflet and part of its symmetric twin at the lower left in the photograph.

I took this picture beneath the power lines west of Morado Circle one month ago today.

    • You’re probably the first person in the world to call two-leaf senna a golden wild beauty. You’d make a good publicist for our native wildflowers.

  2. With you as their photographer, they all look like beauties. We have a senna somewhere around here but I haven’t gotten around to finding it and drawing it. I actually have always liked sennas.

    • It is, and viewing it in nature is free. Instead of stop and smell the roses it’s stop and see the senna.

  4. This is really interesting that there’s an endemic Senna from Texas. This is a genus I began to cover ever since I was in PR, however, since I’ve been here in Florida I realize it is rather extensive, so there’s even more fertile ground to explore the ones here. Most flowers seem to have similar traits. The two leaflets is what characterizes this one. Thanks.

  5. This is lovely. I’ve only seen the Senna lindheimeriana, but I was lucky enough to see both the living plant and one of Lindheimer’s own herbarium sheets featuring “his” senna when the Lindheimer exhibit was at the Sophienburg in New Braunfels. It’s fun that this one bears Roemer’s name. Of all the botanists that traveled Texas in the 1800s, I’d have to say these two are my favorites.

  6. Hey, I HAVE seen that one (I think) half way across the continent! A friend grew it from seed from Texas or Oklahoma. I recognize the species name. I do not know what is so special about it; but then, you would not understand what is so important about the seeds I brought back from there either.
