Fernald (l.c.) says that Lamb’s specimen has stout recurved 
spines scattered along the rhachis of one of the leaves, the remaining 
leaves being unarmed. Lamb’s number 363 is represented by a 
sheet at Kew, but I can discover no trace of spines on any leaf 
rhachis. On the other hand, Jurgensen’s number 619 from 
Mexico (Sierra San Pedro N olasco, Talea, etc.), of which there are 
two sheets at Kew, has one leaf with prominently spiny stipels, 
the other leaves showing no trace of spines. Humboldt and 
Bonpland (l.c.) describe the leaves as being unarmed.

Mazatlan, Lamb 341. 
Lamb’s specimen was determined at the Gray Herbarium as 
C. mexicana var. pubescens Robins. et Greenm. (PAA. xxix. 386; 
1894). It agrees with the description of that variety in having 
the leaflets softly pubescent, but the petals are not ciliolate with 
stipitate glands. Standley says that the species is variable.

Gonzalez’ specimen consists only of flowers sack oui leaves, 
whereas the Kew material, with which I have compared it, 
shows only fruit and mature leaves. Sinaloa is included in the 
distribution of C. platyloba by Standley.
