FERNALD. — MEXICAN PLANTS, 573 
minutely puberulent, the upper half coarsely appressed-serrate, the lower 
half entire and cuneate to a narrow-winged subpetiolar strongly ciliate 
base, including the subpetiolar portion 3 to 5 cm. long, 0.5 to 1 em. wide; 
the upper smaller: peduncles slender, bracteate, elongate, 2 to 6 cm. long, 
bearing 1 or 2 heads about 1 cm. broad: bracts of involucre 3-seriate, 
linear-oblong, the inner 6 mm. long, the outer much shorter, slightly 
ciliate on the margins, with short bluntish herbaceous appressed tips : 
rays white: achene pubescent. — Vera Cruz, wet ledges, Barranca de 
Chavarrillo, alt. 920 m., Apr. 24, 1899 (C. G. Pringle, no. 8118). 
Somewhat resembling A. dullatus, Klatt, but a lower more slender plant 
with shorter broader leaves, broader involucral bracts, and more slender 
peduncles. 
Encelia Pringlei. Stem subterete, scabrous-puberulent: leaves oblong 
or ovate-lanceolate, acuminate, the lower rather abruptly narrowed below 
the middle into an oblong portion which is somewhat auriculate at base ; 
the larger 1.2 to 1.4 dm. long, 4 to 6 cm. wide, above tuberculate- 
scabrous; beneath scabrous, glandular-dotted, and somewhat villous on 
the nerves; petioles very short: inflorescence terminal, corymbose, 1 to 
1.5 dm. across: heads 1 to 1.5 cm. broad, excluding the rays 1.5 cm. 
long: bracts of involucre 2-3-seriate, the outer successively shorter, linear- 
oblong, bluntish, appressed-pubescent and somewhat glutinous: rays 8 
or 9, ovate-oblong, 1 em. long, orange-yellow: achene 6 mm. long, sil- 
very-silky ; the pappus of two lanceolate awn-tipped pales 4 or 5 min. 
long, and two shorter broader somewhat lacerate ones. — Hipaeo, hill- 
idee above Pachuca, alt. 2,770 m., Sept. 14, 1899 (0. G@. Pringle, no. 
8248). With remarkably paleaceous pappus for an Encelia, but appar- 
ently very closely related to Z. glutinosa, Rob. & Greenman.
