  2. Can’t get any more short-and-sweet than that post. Clammyweed is a new one for me.

    • I guess that text is as close to Mute Monday as I’ve come.

      You can check the USDA map at
      http://plants.usda.gov/core/profile?symbol=PODOT
      to see whether you might expect find this species near you. I hope you do, because it’s a fun one to look at. It’s also gooey to the touch, hence the “clammy” in the common name.

      • Thanks for explaining the clammy. From the photo I would call the flower glammy as in glamorous rather than clammy.

        • Now that’s what I like to hear: glammy rather than (or at least in addition to) clammy.

          Eve and I went walking in this location two days ago and saw the clammyweed still flowering.

  3. This MUST be related to the cleome?

    though a little more ‘wild’

    • You’re correct. Clammyweed and Cleome are both in the Capparaceae, or caper family. At least they used to be; an online article I just checked says that Cleome and some other genera gave been moved out of Capparaceae and into Cleomaceae or into Clemoideae (a subfamily within the cabbage family).

      I expect clammyweed will remain wild. Given its gooeyness, I don’t imagine people would want to cultivate it, although to me the intricate flowers have lots of appeal.

      • I had no idea that it was the cabbage family. So clammyweed is…. clammy?

        Heyjude

        October 5, 2015 at 8:39 AM

        • I, too, was surprised to read about a part of the former caper family (including Cleome but not Polanisia) getting moved to the cabbage family. Shifty folks, those botanists.

          Yes, clammyweed is gooey to the touch. The plant also has an easy-to-notice scent that some people describe as unpleasant, but I don’t mind it.

          • I can’t keep pace with all the moves. I always liked to know the Latin name for a plant, but my memory is not the same these days and I find myself settling for the common name…

            Heyjude

            October 5, 2015 at 11:11 AM

            • In the case of clammyweed, the common name is excellent. The scientific name has stayed the same as it was, fortunately, but the genus got moved to Cleomaceae.

  5. Amazing how many wildflowers you have come up with; such interesting or clever names, too.
    I was just outside cleaning up yellowed hostas and cutting off their flower stems. I was reminded
    that thirty years ago a friend gave me my first ones (small and variegated); I asked the name and
    he said ellivino. I hadn’t even seen hostas in South Alabama where I had previously lived. Later I
    clarified the name with him-“Hell if I know!” Always makes me laugh when I think of it.

    • That’s a good anecdote about the name you were given and how you (mis)interpreted it.

      Central Texas is home to hundreds and hundreds of native species, so I have plenty to choose from. Naturally some are much more common than others, so they tend to turn up here more often, but I go out of my way to cover some of the less-familiar species.

  6. This looks very similar to an annual I grow – Cleome spinosa. Do you know why they are called ‘clammy’ weeds? The cleomes feel slightly sticky due to the hairs….

    • Clammyweed and Cleome were until relatively recently both considered members of the Capparaceae, or caper family. An online article I checked this morning says that Cleome has been moved out of Capparaceae and into Clemoideae, a subfamily within the cabbage family. Polanisia has been moved out of Capparaceae and into Cleomaceae. Changes, changes, changes.

      Similar to what you say about your cleomes, clammyweed is “clammy,” which is to say that it feels sticky or gooey when you touch it.

  7. Que grupo floral tan bonito, y que estambres tan largos tienen estas flores. Gracias Steve!

    • De nada, Isabel.
      A este tipo de estambre se le llama en inglés exserted, lo contrario de inserted.

  8. I wonder if those stamens made it into the Guinness Book of World Records. Them’s long. It is a lovely flower even if it is clammy.

    Steve Gingold

    • You raise an interesting question: how freakily long are the longest known stamens in the world?

      Clammyweed may be clammy, but I like it, and I find the flowers quite attractive.

  9. Having roamed the Clammyweed archives, I’ll follow two poets and add:

    I asked myself, with glee, “What is it?”
    As I made my visual visit.

    Are the tips of the stamens green? They seem so — is that unusual? And speaking of those stamens, I was curious about dodecandra. The first thing I thought of was “dodecahedron,” so I went looking and found a couple of references that said dodecandra was chosen because the flower has twelve stamens. That’s pretty neat, and helpful for remembering at least half of its scientific name.

    • I’m good at taking pretty pictures, but I wish I knew more about the botany of these things. Even the largest and most authoritative botanical reference book I have for this area doesn’t give many details, presumably because they’re not important for distinguishing among species. From the picture at

      https://portraitsofwildflowers.wordpress.com/2013/09/17/clammyweed-buds-opening/

      it seems that the anthers at the tips of the stamens start out red, but today’s picture of mature flowers with long stamens makes the anthers look green.

      The reference book I mentioned (like the etymology itself) confirms the 12 stamens of dodecandra. The book also explains that the genus name Polanisia comes from Greek poly ‘many’ and anisos ‘unequal,’ “in reference to the characters by which the stamens differ from those of Cleome.”

  10. Such an interesting flower, I love the intricate detail…Great close-up photo.

    • Thanks, Charlie. “Intricate” is the right word for this species, which I find attractive in spite of the “weed” in the common name.

  11. What fun. Puts me in mind of a flapper doing the charleston with fringes swirling…

    • Someone’s imagination is alive and well this morning. Maybe you could do a drawing or painting of a flapper in motion whose dress you’d make look like these flowers.

  12. Lovely flower and lovely photo. I’ve read all the comments above….does it smell like Cleome? I planted the latter once and couldn’t stand the smell so never did again.

    • Not having smelled any plants in the genus Cleome, I can’t say, but I suspect the smells are similar. I’ve read that some people find clammyweed’s smell unpleasant, but it doesn’t bother me. Each to his own nose, right?

  13. A beautiful capture and a lovely flower!! You should consider posting them more than every second year:)

    • I’ll try to remember. We have so many kinds of wildflowers here that I juggle them as best I can. Some of the more prolific ones understandably get shown more often than others because I encounter them more frequently.

  14. […] As if to corroborate the common name Rocky mountain beeweed, I found a native bee on these flowers of Cleome serrulata at Kasha-Katuwe Tent Rocks National Monument in northern New Mexico on June 12th. An online article about this species notes that other vernacular names for the plant are stinking-clover, bee spider-flower, skunk weed, Navajo spinach, and guaco. This wildflower is a relative of the clammyweed that grows in Austin. […]
