minutel}^ 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 cm, wide ; 

 the upper smaller : peduncles slender, bracteate, elongate, 2 to G cm. long, 

 bearinw 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 2Jubescent. — Vera Cruz, wet ledges, Barranca de 

 Chavarrillo, alt. 920 m., Apr. 24, 1899 ((7. G. Pringle, no. 8118). 

 Somewhat resembling A. bullatus, Klatt, but a lower more slender plant 

 with shorter broader leaves, broader involucral bracts, and more slender 

 peduncles. 



Bncelia 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 cm. long, orange-yellow : achene 6 mm. long, sil- 

 very-silky ; the pappus of two lanceolate awn-tipped pales 4 or 5 mm.

 sides above Pachuca, alt. 2,770 m., Sept. 14, 1899 (C. G. Prwgle, no.

 ently very closely related to E. glutinosa, Rob. & Greenman.
