similarly pubescent monocephalous peduncles; rameal leaves ovate, 

 obtusish, barely toothed, whitened with an appressed scabrous 

 pubescence particularly beneath, 2-2.5 cm. long, 0.9-1.2 cm. wide, 

 short-petioled; involucre 7 mm. high, the scales subequal, in 2 rows, 

 linear-lanceolate, appressed-pubescent and scabrous without; rays 

 suborbicular, 3-lobed, 12 mm. long, pubescent on the back; disk- 

 corollas 5 mm. long, pubescent on tube and teeth; pales 7 mm. long, 

 scantily glandular-pubescent on back, fimbriate at apex; immature 

 achene 4.7 mm. long, villous on margin, appressed-pubescent on the 

 sides, bearing 2 unecjual weak awns, or awnless. 



Encelia albescens Gray, Proc. Am. Acad. viii. 658 (1873). 



Specimens examined: Sonora: 1869, Palmer 21 (GN, cotypes). — 

 A doubtful species, known from very insufficient specimens, too close 

 to E. fnitescens var. acioni. 



++ ++ Mostly herbaceous (except no. 6); heads always radiate, usually some- 

 what racemose; disk purple; awns absent (rarely present in one variety). 



= Frutescent; leaves small, oblong, green; involucral scales glandular-ciliate. 



6. E. conspersa Benth. Slirubby, branched, the scabrous bark 

 white; branches leafy below, terminating in nearly naked 1-3- 

 branched peduncles, the branches monocephalous; leaves oblong to 

 ovate, obtusish, cuneate or truncate at base, green, scabrous-pubes- 

 cent especially beneath, 2-2.5 cm. long, 8-10 mm. wide, on petioles 

 3.5-7 mm. long; peduncles slightly scabrous; disk 1-1.3 cm. in diame- 

 ter, 8 mm. high; involucre 5-6 mm. high, its scales unequal, 3-seriate, 

 the outer lanceolate, the inner ovate, glandular on back and white- 

 ciliate nearly to the tip; rays oval, slightly 3-Iobed, pubescent on 

 tube and back; disk-corollas 5 mm. long, with short tube, glabrous; 

 pales 6 mm. long, about 9-nerved, glandular on the back; immature 

 achenes 2.5 mm. long, villous on the margin, pubescent on the sides. 



Encelia consjoersa Benth. Bot. Voy. Sulph. 26 (1844). 



Specimens examined: Lower California: Magdalena Island, 

 18 Jan. 1889, Brandegee (GN). Bentham's tj^pe came from Bay of 

 Magdalena. — Brandegee's specimens well agree with Bentham's 

 description, except that the branches are not " albo-tomentosis " nor 

 the scales "lineari-lanceolatis." The species must remain somewhat 

 in doubt until Bentham's type can be re-examined. As is suggested 

 in Index Kewensis, it seems in the specimens at hand too close to 

 E. halimifoUa Cav.
