ERIOPHYLLUM 



L. glaberrima DC. Prodr. v, 664. Somewhat fleshy : sterna ascending, 

 6-12 inches long: leaves elongated- linear: heads on long peduncles which 

 are elongated at the summit, nodding in flower : involucre about 15 toothed, 

 corollas all shorter than the minutely puberulenl oblong-linear achenea : 

 pappus of 5-10 rigid palese, two or three of them with subulate or short- 

 awned points, the others erose or lacerate. In saltmarshes along the coast 

 of Oregon and California. 



60 BAERIA F. AM. Ind. Sem. Hort. Petrop. t. 7. 



Low plauts with opposite sessile leaves, and slender-peduncled 

 heads of yellow flowers. Heads mostly many-flowered, with 5-15 

 conspicuous rays. Bracts of the campanulate or hemispherical 

 involucre as many as rays, plain or becoming somewhat carinate 

 at least below. Receptacle subulate to conical. Tips of the style 

 truncate-capitate, with or without a central apiculation, to ovate, 

 sometimes with a cuspidate appendage. Disk-eoroUas with slen- 

 der tube as long or longer than the carnpaniilate 5-lobed limb. 

 Achenes clavate-linear to linear-cuneate. Pappus a few palese or 

 paleaceous awns or both, often wanting. 



B. aristosa. B. gracilis var. aristosa Gray. Slender annual 3-10 inches 

 high, atrigose-pubescent : leaves linear, entire, mostly opposite: involucre 

 3-4 lines high, of 8-10 broadly lanceolate to ovate acute bracts: rays as 

 many as bracts, ligulate, lanceolate, obtuse : achenes linear-oblong, with 

 pappus of 4-5 small palese with awns gradually and slightly widened down- 

 ward and as long as the achene. Dry open places, southern Oregon and 

 California. 



* * Receptacle Hat or comvex. Achenes from linear to ohpyra- 

 midal, rarely $-angled, Flowers (with few exceptions), all fertile. 

 61 ERIOPHYLLUM Lag. Nov. Gen. & Spe. 28. 



Floccose-tomentose or rarely glabrate herbs (rarely sufiruti- 

 cose), with alternate or partly opposite leaves, peduncled or 

 sometimes sessile heads of mostly yellow flowers. Involucre 

 many-flowered, from hemispherical to oblong, commonly epual- 

 ling Ihe disk, of one or sometimes two series of oblong or narrow- 

 er firm-herbaceous or coriaceous permanently erect bracts, 

 distinct or sometimes partially united into a cup: at least in fruit 

 concave in the centre and partially enclosing the subtending 

 achenes. Ray-flowers usually with broad ligules, very rarely 

 none. Disk-corollas with distinct and sometimes slender proper 

 tube. Style-tips truncate, obtuse or obscurely capitellate-conical. 

 Achenes narrow, from clavate-linear to cuneate-oblong, mostly 

 4-angled. Pappus of nerveless and mostly pointless palese. 



E. stsechadifollum Lag. I. c. Canescent with close-pressed pannose 

 tomentum, at length partly denudate, 1-4 feet high. from a woody base: 

 leaves once or twice pinnately parted into oblong or linear divisions, or the 

 upper ones sometimes entire, about an inch long, soon glabrate and green 

 above: heads 3-4 lines high, in rather loose paniculate clusters; involucre 

 cylindraceous-campanulate, of 8-10 linear-spatulate to narrowly- oblonge 

 thinniah bracta : rays 6-8, only a line or ao long, roundish-oval : receptacle
