This is in many respects a very remarkable species. The lower leaves are 
collected at the bottom of the stem, and resemble in form those of E. hera- 
cleoides, flavum, &c., and like them have no stipules. The mode of ramifica- 
tion of the flowering branches is also upon the same principle as in other 
Eriogona (although the ramifications commence from the base of the stem), 
but the leaves, which are placed under the branches, corresponding in number 
to them, have at the basis of each of them a pair of brown scariose stipules, 
not forming a sheath round the stem as in most Polygonacew, but connate 
at their base outside the leaves, and loose at the apex, so as to resemble in 
some measure the stipules of the Polygona Avicularie. The flowering branches 
are remarkably angular, about a foot high; the peduncles slender, and about 
half an inch long; the heads of flowers of the form of those of Galinsogea par- 
viflora, but smaller. The little bracts inside the involucre are dilated at the 
apex, membranaceous on the edge, and bear long woolly hairs on their outer 
surface. The perianth, ovarium and stamina are glabrous. In some, especially 
the dichotomous specimens, one pedicel at the axis of each ramification bears 
only a small abortive involucrum.
