Horse Nettle Flower and Buds 6779

Here are two more wildflowers I saw at the Diamond Grove Prairie in southwestern Missouri on June 4. The first is horse nettle, Solanum carolinense. The second is catclaw sensitive briar, Mimosa quadrivalvis var. nuttalli.

  1. The flowers are a lovely soft contrast to the title. Another take on it could be the beauty in the beast.

    • I like that: “the beauty in the beast.” I endure my share of scratches and punctures to go after the beauty of some of these wildflowers.

  2. Beautiful shots, I particularly like the second one.

    • I don’t remember ever before seeing a sensitive briar flower globe like the one that’s seemingly missing half of its stamens.

  3. Great captures with beautiful detail and color.

    • Thanks, Dan. I was grateful to Scott Lenharth for taking us to this picturesque piece of prairie.

  4. This is a first. I recognized both flowers from your photos. I found Solanum carolinense in a vacant lot next to West Marine just a couple of weeks ago. Unfortunately, I haven’t quite learned my lesson about see-flower-photograph-flower-now. The mowers showed up a few days later, and I’m still waiting to see if there will be more horse nettle in the new growth.

    The view of the sensitive briar is unusual. I take it those are buds in the top flower. I’ve never seen such a thing, whether in real life or in a photo. The flower’s so striking, I’ve probably looked right past the buds. It’s neat that you were able to include the stems, too. Until I learned to look at those stems, I was confusing Mimosa strigillosa with the catclaw sensitive briar.

    There’s an entry from Mr. Smarty Plants on distinguishing the various Mimosa species here. I read it twice, and couldn’t find Mimosa quadrivalvis var. nuttalli. Has there been another renaming, and is this the same plant as M. nuttallii?

    • It seems this sensitive briar has had at least four scientific names:

      http://plants.usda.gov/core/profile?symbol=MINU6

      According to the USDA map, the species is found as close to Austin as Bastrop County, so I may well have seen it without distinguishing it from the Mimosa roemeriana that’s common in Austin.

      I long ago learned the lesson you mentioned, and even on a much shorter scale than from one visit to the next. I’ve observed that on a single outing things—especially light and shadows—can change enough from the outward-bound segment to the return segment that if I see something that looks like it would make a good picture I’d better photograph it as soon as I see it.

      I don’t know what to make of the upper sensitive briar: buds or the beginnings of fruits? Where’s a botanist when we need one?

      • Here’s an entry in an Ozarks wildflower site that surely does suggest that what you found are buds. There’s a great photo of the flowers just beginning to emerge, about halfway down.

        The site’s maintained by an individual, so it’s far from inclusive, but it’s beautifully designed — and it’s double fun that it’s focused on the area I hope to return to this fall.

        • Thanks for finding that site. Definitely buds, I’d say. Now I wonder how typical it is for one side of the flower globe to open ahead of the other.

          May you have a profitable return to the Ozarks with a better camera and more skill to use it than you had on your last visit.

    • And congratulations on recognizing both wildflowers.

  5. These are stunning photos and so interesting to read about. Such contrasts seem to abound in nature!

    • The prairie in Missouri was a good place to take pictures. The prairie in central Texas is equally good, but I enjoyed the change of pace. Both of the wildflowers shown here have closely related counterparts in Austin.

  9. Yet another flower (Horse Nettle) that we have both photographed. The brier not. Both nicely shot.

  10. While I like both images, Steve, the second one catches my eye the most. The brightly coloured filaments really stand out. Are they soft to touch or stiff? Beautiful.

    • The second image caught my eye too. These little flower globes are soft to the touch. The reason the plant is called sensitive briar is that if you touch the compound leaves, all the little leaflets close up in a matter of seconds. You can see that in a video of a related species.

      • Ah yes, I think we have something similar here in Australia. I seem to remember playing with the leaves when I was young. 🙂

        • Plants like these are children’s playthings. I was no longer a child when I saw my first sensitive plant in Honduras in 1968 or ’69.

  11. The second flower, as photographed, reminded me of a burst of fireworks.

    • The sensitive briar does have a fireworks-y appearance, doesn’t it? The plant does exhibit a trait of fireworks, namely movement: touch the plant’s compound leaves and they fold up.

  12. This is just what I was going to say. What a fun plant. To see. I imagine it might not be fun to encounter.

    • The first sensitive briar I encountered was in Honduras in 1968 or ’69, and I still remember it after all these years.
