Discussion
Chamaesaracha darcyi is known from the Rolling Plains of north-central Texas and extends to the Cross Timbers region of Texas and Oklahoma. It is very close to C. coniodes, having a dense vestiture of branched, dendritic hairs like those found on the type of C. coniodes; C. darcyi typically has more deeply incised leaf margins and a nearly prostrate habit.
