soon becoming glabrate and shining above, scarcely paler beneath, ob- 
lanceolate or narrowly obovate, subcuneate at the base, obtuse, rounded 
or even retuse at the apex, 6 to 12 cm. long, 2} to 5} cm. broad, the 
veins prominent beneath, the veinlets inconspicuously reticulated ; petioles 
appressed-pubescent, 9 to 15 mm. long: flowers solitary or in clusters of 
2 or 3, above the axils ; peduncles appressed-pubescent, 1 or 2 cm. long: 
sepals 5, suborbicular, obtuse, imbricated, ferruginous-pubescent, 5} mm. 
long: corolla twice as long as the calyx, cylindric-campanulate, deeply 
cleft into 5 (or 7) oblong obtuse lobes, puberulent, and appressed-ferru- 
ginous outside: stamens and staminodia equally inserted at the top of the 
corolla-tube, the stamens on short filaments equalling the anthers ; the 
staminodia linear-subulate, about equalling the stamens: ovary pubescent, 
5-celled: fruit short-oblong or globular, 3 cm. long, sinuately 5-lobed 
(by abortion 4- or even 1-locular), yellow when ripe; seed 2} cm. long, 
ellipsoidal, laterally compressed, the testa straw-colored and shining, the 
ventral hilum elongated-oblong. — Acapulco, January, 1895 (no. 386). 
Called “ Huicon,” and the yellow fruit eaten. The seed places this plant 
in De Candolle’s section Guapeba, but the 5-parted calyx and corolla 
throw it out of that section and place it near LZ. Rivicoa, Gertn., or 
L. nervosa, DC., in neither of which, however, is the seed laterally com- 
pressed. Dr. Palmer’s no. 1846 from Manzanillo, described by Dr. Rose 
without a name (Contrib. Nat. Herb. i. 339), may be a form of this species 
with much longer leaves and petioles.

2 or 3m. high: stems few, about 2} cm. in diameter, covered with 
smooth pale bark: branches covered with rough reddish-brown bark: 
leaves subcoriaceous, alternate, broadly oblanceolate, 5 to 9 cm. long, 
2 to 3m. broad, blunt or rounded at the apex, tapering below to 4 
short petiole a line or so long, minutely strigillose-pubescent beneath, 
above puberulous, becoming smooth and shining; margins entire, bles 
lute; midribs slightly depressed above, prominent beneath : fruit solitary 
on thick peduncles 2 mm. long, subglobose, 2 or 3 cm. in diameter, 
minutely appressed-pubescent, especially about the persistent base of the 
style; skin thin, greenish yellow; pulp edible: seeds 6, about 1} ¢™

tips recurved. — Acapulco, January, 1895 (no. 372). The yellow fruit
