Bentham’s Chromolepis heterophylla has not been recognized 
among distributed exsiccatae since its original collection by Hart- 
weg (no. 311) in swampy places at Anganguio, State of Mexico, 
in 1836. Examination of specimens of the type collection at the 
British Museum and in the Kew Herbarium has shown its identity 
with Pringle 3668, collected at Del Rio, State of Mexico, in 1890, 
on which was based Leptosyne pinnata Robinson, subsequently 
raised to generic rank as Stephanopholis by the writer in 1913. 
Bentham’s reference of the genus to the Verbesininae is confirmed 
by a careful reexamination of material collected by Pringle, 10 
which the too immature achenes of the disk are thickened and 
distinctly compressed, and the pales slightly folded. Two formae 
are to be distinguished: 
Forma typica: foliis pseudo-pinnatis. — See synonymy above. 
Forma integrifolia (Greenm.): foliis integris. — Leptosyne
