length : lower part of the style as well as the apex of the ovary strongly 
hirsute; ovary 3-celled ; fruit oblong, dark-colored, with slight puberu- 
lence, tipped with the hardened calyx-teeth. — Hills of Patzcuaro, 
Michoacan ; November, 1890 (n. 3345). Resembles in many respects 
S. prionophylla, Hemsl. (ex char.), but has leaves not at all ovate, 
and the petals nearly smooth and united with each other and with the 
stamens for about half their length. In the species just mentioned 
they are described as nearly or quite free. 
GonoLosus PARVIFLORtS, Gray, var. BREVICORONATUS. Corolla 
erect, instead of being reflexed as in the type; the outer crown of five 
short rather thick truncate scales, which are not at all produced into 
lobes at the edges; the inner crown of five horns as in the typical 
form. — Laredo, Texas ; July, 1889 (n. 3029). 
Buppieta CuapaLana. Suffruticose ; branches with a smooth yel- 
lowish bark ; branchlets woolly: leaves ovate or ovate-oblong, 14 to 
24 inches long, an inch broad, appearing more or less rhombic in out- 
line from being contracted at base into a broadly winged petiole, au- 
riculate-perfoliate, acute, rather coarsely and bluntly toothed, woolly 
on both sides when young, becoming nearly smooth at maturity and re- 
taining only a slight mealiness ; floral leaves much smaller, lanceolate, 
scarcely perfoliate : flowers in globular heads ; the heads half an inch 
in diameter and borne in pairs on axillary peduncles about 4 lines 
long; corolla 13 lines in diameter, short, not or scarcely exceeding the 
Woolly calyx. — On dry cliffs in the mountains near Lake Chapala, 
Jalisco; December, 1889 (n. 2972). 
Corpra Prinerer. A shrub 10 to 15 feet high, belonging to 
the section Dasycephale ; branchlets, peduncles and petioles stellate- 
tomentose: leaves ovate or ovate-oblong, more or less narrowed to 
an obtuse apex, often one-sided, all but the smallest abrupt or even 
subcordate at base, crenate-dentate with irregular teeth, green and 
finely stellate-pubescent above, lighter and tomentose beneath, 3 inches 
long, 1 or 2 inches broad ; petioles 6 lines in length: heads globular, 
an inch in diameter on subterminal peduncles 14 inches long; calyx 
_ ‘barrowly campanulate, the tube white-pubescent, and the filiform teeth 
Sstellately ferruginous-pubescent, curled irregularly, mostly reflexed ; 
Corolla funnel-form, white, 5 lines broad, with obtuse lobes: stamens 
meerted near the summit of the pubescent throat. — Las Palmas, San 
~ Luis Potosi; June, 1890 (n. 8091). Differs from C. ambigua, Cham. 
© Schl., in its larger heads and the abrupt or subcordate bases of the 
leaves, 48 well as in the absence of the long spreading hairs on the © 
Petioles and peduncles. Mr. Pringle’s plant much resembles a speci-
