* Leaves all radical, only rarely occtirring in the axils of the hrnrts. — (§ Tedun- 



CULATA, Uentli.) 



•<- Outer segments of the glabrous j^erianth broad and subcordate at base, the inner 



much smaller: pedicels very short, d e flexed : leaves floccose-tonientose. 



16. E. brachypodum, Torr. & Gray, Low and depressed, very divaricately 

 imich-branched and rather rigid, beset throughout (except the leaves) by scattered 

 sliort glandular hairs : leaves densely tomentose both sides, orl)icidai', 3 to G lines in 

 diameter : stem very short : involucres turbinatc-cain})anulatc, half to two thirds of 

 a line long, on pedicels less than a line long, more or less deflexetl : flowers a line 

 long, rose-colored, the outiu- segments cordate-ovate, very obtuse, the inner half as 

 wide, obtusely acuminate. — Proc. Am. Acad. viii. 180. 



Collected only by Rcmij at Kingston Sjiiings on the northcastcin border of San Bernardino 

 County. 



17. E. deflexum, Torrey. Taller and more erect, becoming a foot or two high, 

 glabrous al)ovo the leaves, which arc orbicular, somewhat cordate at ba.so, G to 15 

 lines broad : involucres and pedicels as in the last, but more secund along tho 

 branchlets : outer segments of the light rose-colored or yellowish i)erianth round- 

 cordate, becoming a line long, the inner very small, obovate and rctuse : pedicels 

 reflexed, less than a line long, or rarely a line or more. — Ives' Rep. 24 ; Torr. & 

 Gray, 1. c. 181. 



On the Mohave River {Palmer) and eastward to Utah and E. Arizona. 



H Pauryi, Gray, Proc. Am. Acad. x. 77, is anotlier species of this group, belonging to S. 

 Utah, resembling E. brachypodum, but less rigidly branched, the rather narrowly turbinate invo- 

 lucres a line long and on slender ])ediccls 1 to 3 lines long. E. Hookrri and E. insigne, "Wat- 

 son ined., also of Utah, are more nearly allied to E. deflexum. 



■»- •»- Outer segments of the glabrous 2^'^>'i(t^i^tli' broadest above aiid somewhat pan- 

 duriform, or oblong, emarginate or retuse, the inner ones narrower : jiedicel-s 

 longer : leaves Jloccose-tomentose. 



++ Pedicels deflexed : outer segments oblong or somewhat broader above. 



1 8. E. nutans, Torr. & Gray, 1. c. Slender, erect, 3 to G inches high, mostly 

 glabrous except the leaves, sparingly branched and few-flowered : le^aves rounded, 

 obtuse or acutish, 3 or 4 lines broad: involucres campanulate, a line long, mostly 

 glabrous, but the nodding pedicels minutely viscid-glandular, 2 to 4 lines long : 

 flowers rose-colored, a line long, rather obtuse at base, tho outer segments somewhat 

 broader above and emarginate (nearly obcordale), tho inner oblong and retuso. — 

 Watson, Bot. King Exp. 307, t. 33. 



Lassen County (Bcckivi/h) ; Northwestern Nevada, Watson, Lcmmon. 



19. E. Watsoni, Torr. & (h-ay, 1. c. ]\[ore diffusely branched, a half to a foot 

 higb, glabrous ; leaves rounded, obtuse, often somewhat cordate, a half to an inch 

 broad: involucres narrowly turbinate, 1 -to nearly 1| lines long, attenuate into a 

 slender spreading or reflexed i)edicel 1 to 4 lines long : flowers light rose-color, 

 rather, abruptly attenuate at base, the outer segments oblong and often retuse, tho 

 inner slightly narrower. 



In the West Humboldt Mountains, Nevada, Torrey, Watxon. 



20. E. cernuum, Nutt. Eesembling the last, but with broadly ovate acute 

 leaves, turbinate-campanulate involucres, and flowers more attenuate at base, the 

 outer segments broader above and retuse, the inner oblong and narrower. — PI. 

 Garabel. 1G2; Benth. in DC. Prodr. xiv. 21 ; Torr. & Gray, 1. c. 182. 



Reported as collected ])y Ikrku-ith, with E. nnlnns, on the eastern border of Lassen Countv, 

 and by Nutiall in Oregon ; E. Humboldt Mountains, Nevada {Watson), and frequent in Utah, 

 Coloi-ado and New Mexico.
