Bahia. COMPOSIT.E. 



oil 



Dry plains, common from Santa Barbara southward. Heads somewhat clustered ; the invo- 

 lucre only 2 lines long. Rays generally 5. The state with pappus in the disk as well as ray was 

 collected by Prof. Brewer in the Santa .Maria Valley, Santa luez Mountains, &c 



* * Heads more or less p,ilnnrl,,l t, ruiinoting the branches, with 6 to 8 rays: recep- 

 tacle obtusely conical: anther-appendages abruptly tipped with a eery slender 

 linear-setiform appendage (in the manner of Burrielia ) : pappus both in disk and ray 

 of 8 or 10 chaffy scales. 



G. A. Wallacei, Gray, 1. c. Densely clothed with long and very floccose 

 white wool, at length diffusely much branched, an inch to a span high : leaves 

 obovate or spatulate, entire or somewhat 3-lobed at the apex : scales of the invo- 

 lucre obtuse : pappus of 8 or 10 short and firm oval or oblong obtuse and pointless 

 nerveless scales. — Bahia Wallacei, Gray in Pacif. R. Eep. iv. 105; the form with 

 golden yellow ray as well as disk. 



Var. rubella, Gray : a form with pale purple and white rays. — Bahia rubella, 

 Gray in Bot. Mex. Bound. 95. 



Dry plains, from near Los Angeles and San Felipe, Wallace, Parry (the variety). Also on the 

 Colorado (C«/<'. Bishop), and the southern borders of Utah, P>tl.. , SUer. As yet a rare species. 

 Style-branches tipped with a short subulate cone ! Scales of the involucre involute with aye in 

 the manner of the genus. 



7. A. lanosa, Gray, 1. c. Loosely floccose-woolly, an inch to a span high, at 

 length diffusely branched: leaves linear, mostly entire: scales of the involucre 

 linear-oblong, rather acute : rays white or rose-color: akenes slender: pappus of 4 

 or 5 subulate scales tapering into a slender scabrous awn, and as many alternating 

 oblong and awnless or pointless scales. — Burrielia (Dichccta) lanosa, Gray in 

 Pacif. R Eep. 1. c 



Gravelly hills and plains, on the Colorado, near the Mohave, &c, Bigcloiv, Cooper. Also in 

 Arizona and S. Utah. Style-branches obtuse, or apiculate with a minute cusp. Scales of the 

 involucre almost condnplicately infolded at maturity, enclosing the akene. 



§ 3. Floccose-woolly, depressed, with mostly alternate leaves : involucre narrow : rays 

 8 or 9, small: receptacle flat : a/cenes linear, comjyressed, with callous margins 

 exceedingly villous: pappus of 2 chaffy scales: anthir-ajpi.nl/ag, s oblong- 

 ovate, — ■ Eatonella, i [ray. 



8. A nivea, ( riay, 1. c. An inch or so high, in a small tuft from a slender 

 root, white with soft wool: leaves much crowded, obovate-spatnlate, entire : head 

 barely exserted on a short naked peduncle: scales of the involucre linear-oblong, 

 acute, partly embracing the comparatively large akenes of the ray : pappus of a 

 pair of broadly ovate conspicuous scales tapering into a slender short awn which 

 nearly equals the disk-corolla. — Burrielia nivea, D. C. Eaton in Watson, ll.it. King 

 Exp. 171. t. 18. 



Foot-hills on tl astern side of the Sierra Nevada, Watson. Very likely to occur within the 



State. A remarkable plant, evidently related to the foregoing, bnt it might be regarded as the type 

 of a new genus. Head barely ■'■ lines long. Ravs apparently cither pale yeUow or white. Style- 

 appendages very short and obtuse. Akenes almost ■-' lines long, linear and slightly narrowed 

 downward ; the faces flat, smooth and shining, blackish ; a callous strong rib to each margin, 

 which is densely villous with very long and soft white luu> : scales of the pappus answering t.> 

 the margins. The receptai li 1 a^ convex : but it is flat in the specimen examined, 



naked and scrohiculate. 



89. BAHIA, Lags 



Head many-flowered, with -1 t" 1~> pistill . all the flowers fertile. In- 



volucre a single or more or less double series of thin-herbaceous oval or lanceolate 



apprcssed equal scales, either plat r barely concave, not embracing akenes, dis 



t i in t . or united at base, or rarely foragreater length. Receptacle tl.it . convex, or 

 conical. Rays oval, « •> •• ■ \ . 1 1 • • oi oblong, entire, "i barelj toothed at the apex ; di.-k-
