—S. lasiandra Lyallii Sargent, Gard. and For. 8: 463. 1895.— 
S. Lyallii (Sarg.) Heller, Bull. Torr. Bot. Club 25: 580. 1898. 
This beautiful species was described by BENTHAM from a 
staminate specimen, no. 1954, collected by HARTWEG on the Sacra- 
mento River in California. The cotype in the Gray Herbarium 
is a twig about 12 in. long, not fully in anthesis. The expanding 
leaves are only 2-4 cm. long and 5-9 mm. wide. The aments are 
4cm. long by 5-9 mm. wide. 
The species had previously (1843) been described by NUTTALL 
from specimens observed abundantly on the Oregon and Wahlamet 
(Columbia and Willamette) rivers, and occasionally as far east as 
the Blue Mountains and the Boiseé (Snake) River. 
It is a curious coincidence that FENDLER’s no. 816, collected 
near Santa Fe, New Mexico, and made by ANDERSSON the type of 
his S. Fendleriana, also is a staminate specimen with the aments 
not yet fully in anthesis and the leaves just unfolding. SCHNEIDER 
regards this specimen also as representing the true S. lasiandra 
rather than the green-leaved S. caudata, because, as he states, in 
some of the cotype specimens he has examined the leaves are more 
fully developed and show the glaucous under surface. ‘Two speci- 
mens of this number in the National Herbarium are not sufficiently 
developed to show this. 
The range of this species has been discussed recently by 
SCHNEIDER (Jour. Arnold Arb. 1:17. 1919). Its distribution in 
Colorado and New Mexico, the southeasternmost extension of its 
range, is so restricted, and in a way so separated from the remainder, 
that the specimens known from these two states are listed below, 
in order to stimulate the interest of botanists.
