Like the Opuntia aurea in the previous entry, Peteria thompsoniae is also a species of the American Southwest. It is commonly known as spine-noded milkvetch; the spines are readily apparent in another of Andrey’s photographs: Peteria thompsoniae.
Some BPotD readers may recall an entry from last August with a specific epithet of “thompsoniae”, Penstemon thompsoniae. I had made mention of some initial research into the woman who the penstemon had been named for, discovering that she lacked a Wikipedia page despite her important contributions to botany.
In the months since then, two BPotD readers have worked together to launch a page for Ellen Powell Thompson, detailing some of her biography, her botanical legacy, and her political activism. Many thanks to Dr. David Brownstein (Klahanie Research) and Hollis Marriott for addressing this gap. You can read some of Hollis’s compilation of information in this blog post: Botanist Ellen Powell Thompson—yes, that Powell!. I’ll also add a special thanks to the many people who commented on the Penstemon thompsoniae post, as I know it helped inspire the completion of the Wikipedia page.
Incidentally, Peteria is a genus of 4 species named for Dr. Robert Peter, a Kentucky doctor and botanist (who is also lacking a Wikipedia page). Some of his life is detailed in The Botanical activities and correspondence of Robert Peter, M.D. (1805-1894) and Dr. Robert Peter and the Legacy of Photography in Kentucky.
