E ~ Eriogonum vegetius (T. & G.) 
Perennial, the root woody, ragged, more or less branched at 
the summit and clothed by the dead leaf-bases : stems scapose, at 
first white-tomentose, becoming denuded and green, I-3 dm. high, 
moderately stout : leaves basal, from nearly oval to spatulate or 
narrowly lance-oblong, 2~5 cm. long, white-tomentose, tending to 
become green and glabrate above ; the petioles short or sometimes 
as long as the blade: inflorescence highly characteristic as fol- 
lows: —a single large sessile (or short-peduncled) involucre at the 
Summit of the scape, from the base of which arise a pair of 
peduncles (very variable in length), at the summit of which is 
_ another involucre and another pair of proliferating’ peduncles, — 
such proliferation sometimes occurring a third or even a fourth 
time with constantly shortening rays: floral bracts large and quite 
similar to the lower leaves : involucres several- to many-flowered : 
__ perianths yellow, more or less silky-villous, on rather long but 
ss variable pedicels ; the inner segments distinctly longer than the 
_ outer, all spatulate or obovate: akene angled by a firm narrow 
_ wing-like margin. 
This is the £. Jamesii flavescens of Watson’s Revision (Proc. 
_ Am, Acad. 12: 25 5) and &. flavum vegetius T. & G. Proc. Am. 
Acad. 8: 156. 
__ So far as I am aware no one has heretofore taken up the earlier 
Name of this plant, which is most characteristically distinct, though 
lied to E. Jamesii as placed by Watson rather than to £. favum. 
cé previously very briefly described, a fuller characterization
