33. SALix Uva-ursr Pursh, Fl. Am. Sept. 610. 
From the mountains of New York to Labrador. 
The following species may perhaps be regarded as cespi- 
tose willows, as they are sometimes very low. 
Salix chlorophylla And. from the Rockies and SS. phyllice- 
folia from the mountains of northern New England, which 
closely resemble S. g/aucops, but in these the catkins are 
from naked buds. 
Salix monticola Bebb, from the Rockies, witu pedicelled 
capsules and serrate leaves. 
Undescribed Species from the Southern United States, 
By Joun K. SMALL. 
ALETRIS LUTEA. 
Perennial. Foliage glabrous, yellowish: stems scape-like, 
sometimes broadest above the middle, 4-12 cm. mn acu- 
minate, entire, dilated at the base: racemes 4-20 cm. long, 
with subulate bracts: pedicels barely 1 mm. long: perianth 
yellow, cylindric or constricted above the midd:2 , 8-9 mm. 
ong; segments ovate, spreading: styles united, elongated : 
capsule conic-ovoid, gradually narrowed into the beak ; this 
about one-half as long as the body. 
In low pine lands, Florida to Louisiana. Spring and 
summer. 
Aletris lutea stands between the well-known /letr’s fart- 
nosa on the one hand and Aletriés anrea on the other. 
Doubtless, plants belonging to the species just described have 
been the main cause of the imperfect understanding of A. au- 
rea, chiefly, as far as I can see, on account of the yellow 
perianth common to both species. But beyond this rather 
superficial character the two plants have little that would 
warrant associating them closely. By all other characters of 
importance A/etrzs /utca has its alliance with A. farcnosa, 
having the elongated cylindric perianth of that species as well
