(type), with staminate and pistillate spikes on the same branch, Bur. Sci. 3206 
Mearns, May, 1907, with pistillate spikes. A narrower-leaved form is apparently 
represented by Bur. Sci. 4084 Fenix, from Camiguin Island, Babuyanes, locally 
known as ajas. 
These specimens were previously referred by me to Acalypha stipulacea Klotz., 
which they closely resemble in many respects, differing especially in the points 
noted in the diagnosis above.

Blanco’s description unmistakably applies to this species, and his name being 
the earliest one is here adopted. Cuming’s specimen was from Negros according 
to his own list of localities. The enumeration of “Acalypha tiliaefolia Muell.- 
Arg.” by Vidal seems to have been a slip for “Alchornea tiliaefolia Muell.-Arg.” 
There is no such species as “Acalypha tiliaefolia Muell.-Arg.”
