resemble a good deal those of Hriogonum latifolium, but the in- 
florescence is very different. 
Descr. Root perennial, fusiform, rather thick. Stems, or 
rather Scapes, in our more luxuriant specimens, a foot and a half 
to two feet high, erect, nearly as thick as one’s little-finger in 
the lower portion, terete, woolly. Leaves all radical, on long 
footstalks, sheathing at the base, ovate, cordate at the base, 
more or less woolly when young, but eventually becoming gla- 
brous above and dark green, and white, as well as woolly, be- 
neath. Umbel terminal, large, compound ; general and partial 
umbels of many erecto-patent rays, the latter bearing crowded 
almost spherical umbellules of yellowish-white flowers: all of 
them bracteated. Bracteas numerous, linear-acuminate, resem- 
bling the involucres of an Umbelliferous plant. The true in- 
volucres here are narrow campanulate, six-toothed, hairy at the 
base and apex, three- to five-flowered. H/owers pedicellate, arti- 
culated below the six-sepaled perianth. Stamens nine. Ovary 
elongated, hairy, triquetrous. Styles three. Stigmas capitate.
