Lachnostoma gonoloboides. Stem twining, densely pubescent 
with soft spreading or sometimes slightly reflexed hairs: leaves petiolate, 
oblong-ovate to lanceolate or somewhat halberd-shaped, 5 to 8 cm. long, 
2 to 3.5 em. broad, acuminate, acute, entire, cordate at the base with a 
broad open sinus, hirsute-pubescent on both surfaces, and especially on 
the prominent midrib and nerves beneath, dark green above, paler 
beneath; petioles 2 to 4 em. long, pubescent: inflorescence axillary, 
umbellate; peduncles 12 to 15 mm. long; pedicels 2 to 3 cm. long: 
calyx divided nearly to the base; lobes oblong- to slightly rhombic- 
lanceolate, 8 to 12 mm. long, 3 to 4 mm. broad, obtuse or acutish, entire, 
externally hirsute-pubescent: corolla white, tubular or tubular-campan- 
ulate, 1.5 to 2 em. high, pubescent in the throat; tube slightly exceed- 
ing the ovate obtuse externally pubescent greenish reticulate lobes: 
crown thickish, adnate to the corolla-tube, slightly crenate-margined : 
gynostegium 7 mm. high: fruit not seen. — Mexico. State of Chihua- 
hua: in the Sierra Madre, near Seven Star Mine, altitude 2450 m., 
7 September, 1899, Townsend & Barber, no. 409 (hb. Gr.). A species 
with a distinctly gonolobus-like habit; but on account of the tubular- 
campanulate corolla, the elongated gynostegium, and the pendulous or 
somewhat oblique pollen-masses the plant is ater rather under the 
genus Lachnostoma. 
Irom@A BARBATISEPALA, Gray, Syn. Fl. ii. pt. 1, 212. To this 
species are to be referred specimens collected in the State of Oaxaca, 
Mexico, at an altitude of 1650 m., December, 1900, Conzatti § Gonzalez,

Specimens collected by Mr. C. G. Pringle in the Yantepec Valley, State

Gr.), agree in all essential details with the original of the above species. 
The specimens from Yantepec Valley, however, show a considerable 
variation in the a particularly as to the breadth of the leaf-lobes,
