442 COMPOSITE. 



herbage copiously and permanently white-woolly: rays none: achenes 

 villous; pappus of about 10 oblong-lanceolate pointless rather large 

 paleje.— Plains and valleys east of the Sierra Nevada, from Inyo Co. 

 southward. May, June. 



3. A. niibigeiia. E. mibigenum, Greene, in Gray, 1. c. Stems erect, 

 with loose and open mode of branching, the herbage densely white- 

 woolly: leaves lauceolate-spatulate: heads narrow, short-peduncled: 

 involucre of 5 oblong bracts: rays oval, little exceeding the disk-fiowers; 

 receptacle with small conical elevation in the centre: palese of the 

 pappus about 10, oblong, obtuse, erose, nerveless, one-third the length 

 of the achene.— On Cloud's Rest, above the Yosemite Valley, Mrs. 

 Curran. 



4. A. Wallace!, Gray, Proc. Am. Acad. ix. 198 (1874), and Pac. R. 

 Rep. iv. 105 (1857), under Bahia. Diffusely branched and densely white- 

 woolly: leaves alternate, obovate or spatulate, entire: heads short- 

 peduncled: bracts of the involucre about 8, in maturity somewhat 

 carinate-concave, with scarious margins embracing the ray-achenes : rays 

 short and broad, yellow: achenes glabrous; palese of the pappus 10, very 

 short, obtuse, nerveless.— Inyo Co., Shockley, and southward. The 

 rays are said to be sometimes reddish instead of yellow. 



5. A. laiiosa, Gray, 1. 1. c. c, first as Barrielia. More slender than 

 the last, the leaves almost linear, entire: achenes very slender; pappus 

 of 10 dissimilar palese, 4 or 5 being aristate-pointed, the rest not so: rays 

 either yellow or pinkish.— Range of the last. 



79. ERIOPHYLLUM, Lagasca. Ours mostly perennial or suffru- 

 ticose, floccose plants, usually with divided leaves. Involucres oblong 

 or campanulate, the bracts of firm texture, permanently erect. Rays 

 few, short and broad. Disk-corolla with distinct slender proper tube. 

 Style-tips truncate, obtuse, or obscurely conical. Achenes clavate-linear 

 to cuneate-oblong, mostly 4-angled. Pappus of nerveless and mostly 

 pointless hyaline palese, or, in some small annual species, wanting. 



* Suffruticose; heads smallish, terminally clustered. 



1. E. staichadifolium, Lag. Nov. Gen. et Sp. 28 (1816). Stem and 

 lower face of leaves white with a close pannose tomentum; shrub much 

 branched, 2—5 ft. high, very leafy throughout: leaves subcoriaceous, 

 oblanceolate and entire, or pinuately parted into several narrow divi- 

 .sions: heads compactly corymbose-cymose; involucres oblong, angular, 

 I4 in. high or more, of linear bracts: receptacle convex: rays 6—8:
