Langlassé 1004 (ryrn in Gray Herb.).— Closely related to S. 
Pringlei Rose, to which the present collection was referred by 
Dr. Buscalioni (Malpighia xxvi. 131 (1913)) in his revision of the 
genus. From the type collection of that species, Pringle 4668, it 
differs in a number of significant features. The leaves are more 
densely setose above, particularly on the costa and veins, with 
long and short setae, and the panicles more densely setose with 
longer hairs. The sepals are broader and more overlapping at 
base and more densely covered with setose hairs which are spinulose 
or at base stellate-setulose, while in S. Pringlei the broadly obovate 
sepals, somewhat disjunct at base, are sparsely stellate-pilose but 
_-s Without true setae. Its affinities with S. subalpina J. D. Sm. and 
tum S. latipetala Hemsl., while clearly marked, are not so close. The 
ww Species is dedicated to Dr. L. Buscalioni, editor of Malpighia, 
pro whose revision of Saurauia has been in course of publication in 
= y that journal for some years, and who, it is greatly to be desired, 
iL will present us at the close of his work with a key to all the Ameri- 
fo can species of this exceedingly difficult genus.
