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 Polygonacece, 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 Avicularice. 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 Galimogea par- 

 vijlora, 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.
