Note: Robinson (1979), in his revision of Schistocarpha, also synonymized Schistocarpha triangularis Rusby,
Bull. New York Bot. Gard. 4(14): 392 (1907) with Senecio alternifolius (Sch.Bip. ex Rusby) Greenm. which he
said was ‗Also known as Gynoxys repanda Wedd.‘; this is reflected in the synonymy above. This agrees with
determinations made by Cuatrecasas of Bang 1574 (US - 01418757). However, B. L. Robinson remarked on the
material of Bang 2477 in US that this material (distributed as ‗Eupatorium trichotomum Sch.Bip.‘) was certainly
not a Eupatorium, nor was it Schistocarpha triangularis Rusby, but was apparently a Senecio. This suggests a
mixed gathering. Greenman only cited duplicates of Bang 2477 in MO, and GH. This suggests that it may
have been a mixed collection, and that the material in NY was of a different taxon. Currently much material
is determined as this taxon, with widely differing leaf size and shape, doubtless representing several new
taxa.
