there are specimens in the Kew Herbarium of two other species of 
Sapium from Mexico; or, possibly, one of them may belong to 
Stillingia, as defined a entham and Hooker’s Genera Plantarum. 
But, it should be added, the limits of Sapiwm, Stillingia, Eacecaria, 
and some other allied genera have been so diversely interpreted by 
different botanists that their proper limits could only be defined, if 
even then, after a thorough study of all the numerous species of this 
group of the Euphorbiacee. 
The other assumed species of Sapiwm from Mexico are : sas ahi 
3020, from Santa Afia, near Orizaba, and Rovirosa, 769, ‘habitat 
in Famulté sylvis primeevis, Tabasco.’ The sa aa is a sterile specimen, 
and is very similar to S. mexicanum, but differs in having oblong 
leaves, thicker in texture, and furnished with @ a prominent apical 
gland. The latter is the as a sterile specimen in the Berlin 
nd. same 
Herbarium labelled : ‘Schiede, 44. Vera Cruz, in sylvis.’ It is the 
manuscript name of ‘ Micws sapioides, Kl.’ in the Berlin Herbarium. 
The following is a description of Rovirosa’s specimen, so far as it goes.

n. 
Hahn, 882, from Martinique, and Trail, 765, North Brazil ; both, 
however, napa different from S. later iflorum, Hemsl., and from 
each other. The former has small leaves with close lateral veins, very 
thick flowering- bonkidies and rigid androgynous flower-spikes, longer
