The unnamed watercourse where specimens were collected is a first-order stream that drains Blackland Prairie remnants and mixed hardwood forest, emptying into the Cahaba River. During the seasonally heavy rains of winter, sheet flow across the soil surface is common. The watercourse is essentially permanent, with deeper pockets and pools holding water even in the driest months (J.D.D., pers. obs.).
