Xerophyte

Proc. Amer. Acad. Arts 3: 284. 1856 [Mar ? 1856] Remarks: Engelmann published this infraspecific name as: "C. Phoeniceus [variety or sub-species] C. Conoideus" [Protologue "... A specimen among Dr. Bigelow's collections seems to unite this form with C. phoeniceus, where for the present it is perhaps best to leave our plant, as a variety or sub-species."
