OWLEE cites Pringle’s no. 6795 as type of his S. Pringlei and says “‘no 
staminate plant was collected,” but the specimens before me consist of male 
and female material. Furthermore, ROWLEE states that the pubescence 
of the leaves is ‘‘slightly ferruginous” and that the leaves are ‘‘at maturity 
becoming nearly glabrous.” As I have already pointed out, RowLEE’s descrip- 
tion does not fit exactly the material distributed under no. 6795, and I think 
it best not to use the name Pringlei for the variety because there may be 
hybrid forms. RowLeE apparently overlooked the original description of 
paradoxa. He says that his species “‘is related to S. candida” which, in my 
opinion, has nothing whatever to do with the Mexican plant. 
The var. ajuscana differs chiefly from S. paradoxa by its almost entirely 
yish pubescence, the more elliptic or elliptic-ovate shape of the leaves, 
the shorter style of the ovaries, and the smaller size of the fruiting aments.
