and Arizona ; Southern Utah, (Palmer.) 
Eriogonum corymbosum, Benth. T. 4* G.^ I. p. 170. ( § Corymbosa. 
See Appendix, under EriogonecB.) Shrubby, 1^-2° high, floccose-wooUy, 
the stout woody branches erect or assurgent, leafy to the top, terminated by 
a broad full-flowered cyme upon a short or rather long peduncle ; loaves 
oblong, subundulate, 8-18" long ; flowers white, U" long, usually rather thick 
at base after flowering, glabrous within, segments obovatc, inner ones at h^ast 
emarginate or retuse ; ovary often scabrous above upon the angles. Utah 
(Frt^mont and Gunnison) and New Mexico. 
Eriogonum microtiiecum, Nutt. 2\ S^- G., /. c, j?. 170. Shrubby, rather 
low, (rarely 1° high,) very much l)raiiched from the base ; tomeutum floccose, 
sometimes rather thin; branches as in the last, luif ilie cyme either crowded 
or eff'use; leaves narrowly oblong aiul liiu^'ur ; tlowcrs wliite or rose-colored, 
rarely dull-yellow, seldom over 1" in length, usually raUicr thick at base after 
flowering, glabrous within, the segments and ovary as in the last. — In various 
forms from Nebraska to New Mexico and west to Northern California and 
Washington Territory. The typical form is low, with linear or linear-oblong, 
(occasionally oblong,) nearly flat leaves, and open corymbose cymes on rather 
long peduncles ; involucres long; uniformly rather slender and graceful 
in habit. Frequent in the mountains from the Sierras to the Wahsatch, espe- 
cially in Nevada, with the blade of the leaves G-12" long and 2-3" wide, 
peduncles 2-4' long, and elongated leafy stems ; 5-9,000 feet altitude ; July- 
September. (1,023.) 
A dwarf alpine form with the leafy stems but 1' long, peduncles 
in length and small whitish or deep rose-colored cymes, was found on the 
East Humboldt Mountains, at 10,000 feet altitude ; August. (1,024.) 
Rather imperfect specimens were collected at the base of the Pah-Ute 
range, Nevada, at an unusually low elevation, more densely tomentose, the 
stems and peduncles rather stout and strict and ihr. branchlets of the loose 
spreading cyme short and stifl"; flowers palc-ycllow, few in the involu- 
cres. (1,025.) 
Specimens from the Wahsatch at 6,000 feet altitude, with very short 
(?') leafy stems and slender almost scapelike peduncles, (4' long,) briglit- 
yellow flowers and rather oblon": leaves, are intermediate between the typical 
form and the following variety. (1,026.)
