tains, at the head of Touchet river. Single specimens of this species 
form dense cespitose mats often a foot in diameter. 
SIDALCEA HENDERSONI Wats. This species was described from a 
single plant, supposed by its discoverer to be a waif, collected in 1886 
at Clatsop beach, Oregon. As long ago as 1887 I collected a single 
specimen of it on the sea beach near Seattle, and last year found it in 
abundance in the brackish marshes at the mouth of the Snohomish 
river near Everett. It is a beautiful species with deep rose flowers 
nearly an inch in diameter. Apparently it is confined to the imme- 
diate proximity of the sea. 
Astragalus Palousensis, n. sp. Perennial from a stout woody cau- 
dex : stems several, 40 to 60™ high, simple or branched above, striate, 
sparingly pubescent with short appressed hairs, these white below and 
blackish above: leaves 8 to 12™ long; leaflets 25 to 31, elliptical or 
lanceolate, obtuse or even truncate, appressed pubescent beneath, 
glabrous above, 5 to 20" (usually about 1 5™) long, nearly sessile ; 
petioles sparsely hirsute; stipules deltoid-acuminate : racemes elon- 
gate, 5 to 12™ long; flowers 20 to 25, erect on short pedicels, 12” 
long ; bracts lanceolate, shorter than the calyx: calyx obliquely cam- 
panulate, the slender teeth nearly as long as the tube, pubescent with 
short appressed black hairs: corolla pale yellowish, with or without a 
black spot on the wings: pod 2™ long, crustaceous, narrowly oblong, 
tipped with a slender short beak, its surface transversely reticulated 
and sparsely pubescent with short white hairs ; stipe as long as the 
calyx tube or shorter. 
Common on rich loess hillsides about Pullman. 
Very closely related to A. reventus Gray, and A. arrectus Gray. 
From the latter it differs in the much shorter stipe and beak of oe 
pod ; from the former in its more elongate raceme, in the leaves being 
glabrous above, and in the much shorter and sparser pubescence of the 
Owers 
This species has not hitherto been 
Teported from west of the Rocky mountains. It has been collected by 
Whited at the head of Twisp river, Cascade mountains, and by - 
writer near the source of the Duckaboose river, Olympic mountains. 
The specimens from the latter place are very well developed, some of 
the leaves being three inches in diameter.
