SPECIMENS EXAMINED.—Mexico: State of San Luis Potosi, “ex convalli

From S. Hartwegii this species is easily distinguished by the characters 
given in the key. Unfortunately, I have seen only female specimens, accord- 
ing to which it seems to be most closely related to S. asiolepis, of which I have 
seen a form of southern California with half-evergreen leaves, the aments 
appearing in the axils of the remaining leaves. But this species differs in the 
almost glabrous or much less pubescent leaves, in the longer cylindrical flower- 
ing aments, and in the longer gland which is two-fifths to one-half as long as 
the pedicel.

T refer these specimens to S. Jasiolepis mostly on the authority of C.'R. 
Batt, who determined the sheets of the Washington Herbarium. He has 
already made an extensive study of the species and forms of the sect. Cor-

* There are two places of this name in Mexico according to Rand McNally’s 
map, one in Jalisco, the other and apparently more prominent in Vera Cruz, about 
55 km. west of the peak of Orizaba. Henstey in Biol. Centr. Am. Bot. IV: 134. 1887. 
hates that “Wilhelm” Schaffner has sent plants to Dr. Gray “from the neighbour- 
Ponsa of San Luis Potosi” and that he collected also at Orizaba but not in Jalisco. 
This Wilhelm” Schaffner is undoubtedly the same as “Dr. J. G. Schaffner” as 
Printed on the labels before me.
