354 COMPOSITE baeria 



ERIOPHYLLUM 



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

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

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

 corollas all shorter than the minutely puberulent oblong-linear achenes : 

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

 awned points, the others erose or laciniate. In salt marshes along the coast 

 of Oregon and California. 



60 BAERIA F. & M. Ind. Sem. Hort. Petrop. t. 7. 



Low plants 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-corollas with slen- 

 der tube as long or longer than the campanulate 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, strigose-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 ?s the achene. dry open places, southern Oregon and 

 California. 



* * Receptacle flat or convex. Achenes from linear to obpyra- 

 midal, rarely 5-angled. Flowers (with few exceptions), all fertile. 



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



Floccose-tomentose or rarely glabrate herbs (rarely suffr * ti- 

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

 sometimes sessile heads of mostly yellow flowers. Involucre 

 many-flowered, from hemispherical to oblong, commonly equl 

 ailing the disk, of one or sometimes two series of oblong or 

 narrower 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. staechadifolium Lag. 1. c, Canescent with close-pressed pannose 

 tomentum, at length partly denudate, 1 to 4 feet highfaom 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-oblong 

 thinnish bracts: rays 6-8, only a line or so long, roundish-oval : receptacle
