A new oddity
On March 10th I went back to the lot along Balcones Woods Dr. where I’d photographed the stemless evening primrose flowers you saw here not long ago. The highlight of my latest stop was a strange ten-petal anemone flower (Anemone berlandieri) that had two central fruiting columns instead of the one that’s normal.
Sometimes flower parts get doubled as part of the phenomenon called fasciation, which I’ve documented in a bunch of posts over the years, but this time I didn’t see any of the noticeable flattening or distortion or elongation that fasciation typically brings with it. To continue investigating, I returned to the site on March 16th. By then the richly colored sepals had fallen off and dried out or blown away, so I had to search for several minutes to find the plant again. While the new evidence shown below argues against fasciation, what caused the rare splitting of one seed column into two remains a mystery. (I call this conjoining rare because even a local expert like botanist Bill Carr says he’s never seen an anemone do this.)
