CAYUGA FLORA (1926) NOTES: In somewhat drier and more alluvial woodlands than C. bulbosa; frequent, locally very abundant. Apr. 20-May 15. Around swamp w. of Key Hill ; Inlet Valley, both s. and n. of Ithaca, abundant; Caroline Depot; Beech Woods, Six Mile Creek; Fall Creek; Ellis Hollow; along Fall Creek, above Freeville ; and elsewhere. Conn, to s. Ont. and Wis., southw. to Md. and Ky.; rare or absent on the Coastal Plain. No good characters have been found to separate this from C. bulbosa. The often-cited differences in shape of leaf are not apparent, and there is no constant difference in shape and size of flower, though the flowers of C. bulbosa are occasionally smaller. The differences in color of flower, pubescence, height, and time of flowering, are those of degree only, and one or more are frequently not evident. Perhaps color of flower and height are the most constant.
