1918] SCHNEIDER—SALIX 9 
TYPE LOCALITY.—‘In omni ripa et in insulis sabulosis flum. Amazonum 
a Gurupa (prov. Para in Brasilia) at Peruviam usque frequens.”’ 
NGE.—This variety seems to be confined to the territories of the Amazon 
and Solimoes River in Brazil, and probably in the adjacent part of Colombia. 
SPECIMENS EXAMINED.—Brazil; Prov. Para, “in vicinibus Santarem,’’

locality (Herb. Lehmannianum, B.T. 1261, f., fr.). 
he material before me is much too scanty to judge the value of this variety. 
The main characters by which it may be separated from typical S. Humboldti- 
ana seem to be the presence of a dorsal gland in the pistillate flowers and the 
more elliptical shape of the somewhat larger capsules. In Sprucr’s specimen 
about 21 mm. wide. LryBoLp gives as another distinguishing character the 
hairy pedicels which, however, are glabrous on the specimens before me. 
This form needs further investigation.
