A specimen from Acapulco (Guerrero), Palmer 305, probably 
belongs here, but the fruits are only slightly compressed, and 
are abruptly rounded at the apex with a small apiculus instead 
of being gradually narrowed. 
Houston’s specimens (the type of Mimosa campeacheana) are 
without flower or fruit, but agree with the other material above 
cited in the spines and leaves. The description of A. cymbispina 
has been drawn up mainly from Palmer’s no. 101. 
The new name Acacia cymbispina is required as the name 
A. campeacheana has been used for another species by Schenck 
(Fedde, Repert. xii. 361, 1913; Engl. Jahrb. 1. neue 465, 1914).
