31. Satix DopcGEANa. 
A delicate suffruticose little plant, scarcely more than 2 cm. 
high above ground: stems slender, but short, mostly subter- 
ranean, with brown bark ; ; shoots, at least when young, with 
yellowish green bark, densely covered with leaves, the whole 
plant perfectly glabrous except the margins of the bracts; 
leaves 4-5 mm. long, oblong or oval, acutish or obtuse, light 
green, strongly veined ; pistillate catkins generally 2-flowered ; 
bracts oblong, truncate, sparingly villous-ciliate ; ; capsule ob- 
long-ovoid, glabrous, with two sessile 2-cleft stigmas; stam- 
inate catkin sgenerally 3-4-flowered ; stamens 2, with slender 
glabrous filaments more than twice as long as the bracts, and 
short anthers. 
This is nearest related to S. rotundifolia, which, however, 
has nearly orbicular, often emarginate leaves and more 
strongly ciliate obovate bracts. S. Dodgeana is, as far as 
known, the smallest willow in existence. At the original lo- 
cality it was found covering whole acres of ground, growing 
on the mountain side at an altitude of 3200m. Mr. Tweedy 
collected his specimens at about the same altitude. It is dedi- 
cated to Mr. William E. Dodge, of New York City, a sincere 
friend and patron of botany.

which apparently belong to this species, have been collected
