Since the publication of our Philodendron affine, the leaves in Wendland’s herbarium, 
upon which Schott founded his Philodendron anisotomum, have been compared by 
Mr. N. E. Brown with Mr. Salvin’s specimens of our plant in the Kew Herbarium, 
and he regards them, probably correctly, as the same species; but we do not feel 
justified in actually reducing our species, because a species founded upon leaves alone 
hardly deserves recognition, and it is too late to cancel our name on the plate. Engler 
(in DC. Monogr. Phanerog. ii. p. 412) treats Philodendron anisotomum, Schott, as a 
variety of his own more recently described Philodendron fenzlit, which is apparently 
distinct from our P. affine, at least.
