808 RypBERG: STUDIES ON THE Rocky MOUNTAIN FLORA 
2-3 dm. high, trichotomously branched, with ascending branches; 
bracts triangular, 5 mm. long or less; involucres in the lower forks 
short-peduncled, the rest sessile, glabrous, turbinate, 3 mm, long; 
lobes rounded, scarious-margined; perianth white, glabrous, 2-2.5 
mm. long, campanulate; divisions equal, obovate; filaments 
slightly hairy below; ovary glabrous. 
In habit and leaf form this species resembles E. spathulatum 
A. Gray, but the involucres are glabrous instead of tomentose, and 
the lower ones are peduncled; the stem is also perfectly glabrous. 
It differs from E. tristichum Small and E. salicinum Greene in its 
broader leaves and the scarious-margined lobes of the involucre. 
Jones’ specimens are smaller and more cespitose than the type.

Dr. J. K. Small has for some years regarded this as a distinct 
species, and it is found in the herbarium of the New York Botanical 
Garden under a manuscript name of his, which, however, was never 
published. | x 
Eriogonum ramosissimum Eastwood is related to E. Wright 
Torr. and does not belong to the corymbosum group, tO which 
it was referred. 
Eriogonum crassifolium Benth. is the same as the original B- 
flavum Nutt. What Coulter & Nelson and others have regarded 
as E. flavum should be known as E. chloranthum Greene. E. 
aureum Nutt. is the same, but the name was first published as @ 
hyponym, and when finally it was properly published there was 
already an E. awreum Jones. 
Torrey and Gray, in their revision of Eriogonum, described E- 
strictum Benth. as having subequal sepals, and they have beet 
followed by S. Watson and others. Bentham, in his ors nal 
description of the species, did not mention whether the perianth
