240 NELSON: NEW PLANTS FROM WYOMING 
may be of service. It occurs from southern Wyoming to New 
Mexico and specimens of it are not rare. Excellent ones were 
secured at Sherman, Wyoming, in August, 1901, 70. 8574. 
Eriogonum salinum sp. nov. 
_ Perennial, from a low freely-branched woody base or caudex, 
with dry shreddy bark : herbaceous stems simple, erect, leafy, 1-2 
dm. long, terminating in a short naked peduncle: leaves narrowly 
lanceolate, rather crowded, mostly erect, subsucculent, white with 
a fine closely-felted tomentum below (as are also the stems, and in- 
florescence), short-petioled, glabrous above but very pale, 2-3 cm. 
long: inflorescence a short broad-topped crowded irregular cyme 
(not more than 8 cm. high and usually much less), the branching 
mostly trichotomous but often with some smaller accessory rays ; 
the lower bracts 1 cm. long or less, linear, the others greatly re- 
duced : involucres narrowly turbinate, subsessile, several-flowered, 
their teeth seemingly obtuse but when divested of their tomentum 
sharply acute: perianth small, white, its segments obtuse, often 
apiculate; the outer oblong-elliptic; the inner longer than the 
outer, obovate: stamens and style-branches included; ovary 
glabrous. 
Allied to &. microthecum Nutt., and to E. effusum Nutt., but 
quite distinct from either. The season’s branches are simple and 
permanently leafy. The tomentum is of a different character from 
that of the allied species and the leaves on the upper surface have 
in the dried state a somewhat glistening or unctuous appearance. 
The short inflorescence, forming so small a part of the whole 
height of the plant, is in sharp contrast to the ample inflorescence of 
its allies. In this respect it suggests Z. Jonesii Watson. 
This species is an inhabitant of strongly saline soils, as its ap- 
pearance would suggest. The type was secured on Salt Wells 
Creek, Sweetwater Co., July 17, 1897, and is mo. 3753. It was 
distributed as £. effusum Nutt.
