Catale, Indian Territory, 1894; Dr. Chas. Mohr at Apal- 
achicola Bay, 1892; Mr. Nash at Eustis, Lake Co., Flor- 
ida, 1894; Mr. Ashe in Brunswick Co., N. Carolina, 
1895; Mr. Heller in Kerr Co., Texas, 1894; Mr. Wright 
in N. Mexico, 1851. The writer has examined the avail- 
able material from all the places mentioned, and he is 
under obligations to the U.S. National Museum, the Mis- 
souri Botanical Garden, and the Gray Herbarium of Har- 
vard University, as well as Messrs. Bush, Eggert, Mohr, © 
and Ashe. 
An impartial investigation can no longer leave any doubt 
that Andersson’s description of S. longipes, Shuttlw., in his 
monograph, covers all essential points inclusive of S. 
Wardi, Bebb, and that the latter name as distinctive of the 
species should be dropped. Inasmuch as the name WS. occi- 
dentalis, Bosc, 1824, was applied to a species growing in 
the island of Cuba, and the material not at hand to show 
its relation to S. longipes of the United States, it seems 
best not to speculate on the matter. Mr. Bebb from the 
very first saw that the peculiar willow referred to him by 
Mr. Ward for identification, was allied to S. longipes (see 
Fl. Washington). His later separation of it into a distinct 
species can only be accounted for on the ground of insufii- 
cient material. As late as September, 1895, after the date 
of publication of the new species, he wrote me, ‘* having 
only a beggarly account of unsatisfactory material of S. — 
longipes,’’ and, in the same letter, referring to my descrip- 
tion of S. Wardi, writes ‘‘ here is something which 
puzzles me ‘the pubescent growing shoots hoary and 
heavy’ of S. Wardi—this surely is a local departure 
for there is not a trace of anything of the kindon Wardz.’’ 
This mistaken idea of Mr. Bebb’s probably affords the clue. 
S. longipes was regarded as pubescent and by various 
degrees merging into the still more pubescent S. occident- 
alis. Now the fact is, the so-called Wardi has usually 
hoary pubescent shoots, and in many cases pubescent leaves, 
their pubescence however being lost before full maturity.
