1. Eriogonum rhodanthum A. Nelson et P. B. Kennedy, l. c., p. 35. 
Perennial, acaulescent, very low; caespitose, densely tomentose; the 
caudex made up of many strands twisted together like a rope, its 
numerous branches terminated by clusters of very small, new and old 
leaves: leaves 7 mm long orless with petioles about 4 mm long, tomen- 
tose on both sides, ovate to suborbicular: scapes very slender, from 
12 mm —5 em high, darkred, covered with a loose white tomentum, and 
terminating in a flower cluster about 12 mm across: involucres 2 mm 
long, about 5, each with 8 densely tomentose, linear lobes: perianth 
rose-colored, 3 mm long, its lobes broadly obovate, glabrous, with a 
single strong brown vein: pedicels 3 mm long; filaments 1 mm long, 
villous below: ovary glabrous. : 
. It forms dense mats from 1—6 dm across, on hard rocky ground.

Allied to E. anemophilum Greene, but different in the character of the 
caudex, foliage, and color of the flowers. 
2. Eriogonum rosensis A. Nelson et P. B. Kennedy, |. c., p. 36. 
Perennial, acaulescent,  woolly-tomentose, caudex branched and 
covered with numerous (new and old) persistent leaves: leaves 6 —12 mm 
long, ovate, tapering to a petiole 4 mm long, woolly-tomentose on both 
sides: scapes 1-several from each branch of the caudex, rather stout,
