A few of these were scattered here and there.
Not easily visible from the photo, but it has a flagellum which propels in in the direction the flagellum is facing.
Pill-shaped organism.
For my 10,000th observation, I'm going back to 2015 with a special little Euphorb that helped change the way I thought about Euphorbia fendleri. This little population is special in that I perceived it as intermediate between the Texas E. fendleri and E. chaetocalyx when I saw the specimens. This paved the way for me to understand what was really going on when I went to Utah in July 2015. When I saw the Utah plants, it clicked that they were morphologically identical to the Indian Hot Springs plants of Hudspeth Co. Texas. I finally got a chance to see this one in person later in July and these photos represent that occurrence.
I also saw E. cryptorubra on the same trip which led to the description and the etymology specific epithet. Ironically, I was so excited at seeing the plants that I didn't really take the greatest photos, even after telling myself the whole way there to take some time to get good photographs. I can't imagine how bad they would have been if I hadn't been telling myself that. I guess there was a light shower that didn't help too, but honestly, that wasn't the main culprit of my negligence.
