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 unequal 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. frutescens var. actoni. 
++ ++ 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. Shrubby, 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 em. 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-lobed, 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 conspersa Benth. Bot. Voy. Sulph. 26 (1844). 
Specimens examined: Lower Ca.trornta: Magdalena Island, 
18 Jan. 1889, Brandegee (GN). Bentham’s type 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. halimifolia Cav.
