This northern species was reported from Ky. by Mulligan (1980), but details remain unknown (Cr, M). There are also records of uncertain status from Va., N.C. and Fla. (W). C. bulbifera is clearly distinct from maculata, with plants producing bulbils in axils of upper leaves and flowers usually aborting; also, leaf segments are narrowly linear (versus linear to lanceolate).
