GREENMAN. — MEXICAN PLANTS, 299 
late, oblong-ovate to broadly ovate, 4 to 8 em. long, 2 to 5 cm. broad, 
short-acuminate, entire, usually cordate at the base, finely pubescent upon 
either surface, especially upon the prominent midrib and the strongly 
reticulate veins beneath, above dark green, paler beneath: petioles canalic- 
ulate, 1 to 3 cm. long, puberulent or finely pubescent, bearing at their 
bases 2 or more small subulate stipule-like structures: inflorescence in ax- 
illary pedunculate minutely pubescent cymes; peduncle 2 cm. or more 
long; pedicels 1 to 14 cm. long; calyx deeply 5-parted; divisions lance- 
linear, acute, about 4 mm. in length: corolla salverform, greenish yellow or 
sometimes purple; tube 22 mm. long, strongly contorted at the middle, 
provided at the orifice with an adnate subcuneate crown and bearing on 
the inside just above the attachment of the stamens a tuft of long villous 
hairs ; lobes broadly obovate, 8 to 9 mm. long: anthers pubescent on the 
outer surface: carpels villous-pubescent: fruit reaching a length of 3 dm.; 
seeds about 2 cm. long. — Collected by C. G. Pringle, on lava beds near 
Cuernavaca, altitude 1,600 m., 23 September, 1896, no. 6554. 
. Astephanus pubescens. Stems slender, twining, finely striate, 
pubescent: leaves short-petiolate, lanceolate to ovate-lanceolate, 14 to 
6em. long, 4to 20 mm. broad, acute at the apex or sometimes submu- 
Cronate, obtuse at the base, entire, sparingly pubescent on either surface: 
petioles 2 to 4 mm. long, pubescent: inflorescence in subumbellate short- 
pedunculate several flowered axillary clusters; peduncles 1 to 2 mm. 
long: flowers on slender pubescent pedicels, the latter about 3 mm. in 
length : calyx minute, 5-parted, pubescent on the outer surface, provided 
on the inside with 5 small oblong glands alternating with the lobes: divis- 
tons ovate, acutish: corolla subcampanulate, about 3 mm. in diameter, 
deeply 5-lobed, white or tinged with brownish purple: lobes dextrorsely 
Convolute in the bud, oblong, emarginate at the apex, spreading, later 
becoming somewhat reflexed, the upper inner surface, as well as the 
*orolla-tube inside, granular or almost lepidote: fruit not seen. — Col- 
ted by C. G. Pringle, on a wet barranca above Cuernavaca, altitude 
2,000 m., 21 September, 1896, no. 6507, and in the mountains near 
Cuernavaca, 8 August, 1896, no. 7203. A plant with the habit of 
“astelma, or of Vincetoxicum, but by the entire absence of a crown, or 
at most by a very rudimentary one, its affinity is rather with the genus 
Astephanus, notwithstanding the presence of the minute glands at the 
‘inuses on the inside of the calyx. 
Gonolobus chrysanthus. Stems twining, greenish purple, granu- 
lose, interspersed with spreading or subreflexed hirsute pubescence : leaves 
°vate-oblong, acuminate, obtusish at the apex, a deep narrow open sinus
