Other info. - This is a tiny
plant which can be easily overlooked. The plant produces a "moniliform"
rhizome, which means "constricted at regular intervals" (like a pearl necklace,
for example). It sort of resembles roots infected with nematodes.
Fortunately, I like scorpions. I used to breed a few different species and donated part of my collection to a fellow named Kari McWest, so he could finish his graduate research. Kari - drop me a line.
