Eriogonum. POLYGONACE.E. 23 



* Leaves all radical, onlij ravel j orrurrlnrj hi the axils of the bracts. — (§ Pkdun- 

 CULATA, Beiitli.) 



•i- Outer segments of the filahrous perianth broad and subeordate at base, the Inner 

 much sill a Iter: pedlrels very short, deflexed : leaves floccose-toinentose. 



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

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

 short glandular hairs : leaves densely tomentose both sides, orbicular, 3 to 6 lines in 

 diameter : stem very short : involucres turbinate-campanulate, half to two thirds of 

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

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

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



Collected only by Remy at Kingston Springs on the northeastern border of San Bernardino 

 County. 



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

 glabrous above the leaves, which are orbicular, somewhat cordate at base, 6 to 15 

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

 branchlets : outer segments of the light rose-colored or yellowish perianth round- 

 cordate, becoming a line long, the inner very small, obovate and retuse : 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 eastwanl to Utah and E. Arizona. 



E. Parryi, Gray, Proc. Am. Acad. x. 77, is another species of this group, belonging to S. 

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

 lucres a line long and on slender pedicels 1 to 3 lines long. E. Hookeki and E. ix.sigxk, Wat- 

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



-t- -t— Outer segments of the rflnhrnvs perlanfh broadest above and somewhat pan- 

 durlforni, or oblong, emu rgiimf,' or retuse, the inner ones narrower : pedicels 

 longer : leaves floccose-tn me iiti ise. 



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



18. E. nutans, Torr. & Gray, 1. c. Slender, erect, 3 to 6 inches high, mostly 

 glabrous except the leaves, sparingly branched and few-flowered : leaves 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, the outer segments somewhat 

 broader above and emarginate (nearly obcordate), the inner oblong and retuse, — 

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



Lassen County (BcckwiUi) ; Northwestern Nevada, Watson, Lemmon. 



19. E. Watsoni, Torr. & Gray, 1. c. More diff'usely branched, a half to a foot 

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

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

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

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

 inner slightly narrower. 



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



20. E. cernuum, Nutt. Resembling 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. 162 ; Benth. in DC. Prodr. xiv. 21 ; Torr. & Gray, 1. c. 182. 



Reported as collected by Becknnth, with E. nutans, on the eastern border of Lassen County, 

 and by NiUfaJl in Oregon ; E. Humboldt Mountains, Nevada ( iratson), and frenucnt in Utidi, 

 Colorado and New Mexico.
