314 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
small lenticels; leaves 10 to 15 mm. long, obcvate, retuse, somewhat cuneate at base; 
petioles 2 to 3 mm. long; stipules ovate, with scarious margins, persisting even after 
the leaves have fallen; flowers axiliary, solitary but appearing as if clustered on 
account of the very short internodes; peduncles | to 2 mm. long; calyx teeth ovate, 
fruit 6 mm. long. ; 
Collected by C. G. Pringle on rocky hills near Tehuacan, Puebla, August 3, 1897 
(no. 6771). 
It was distributed as a doubtful EF. brevipes DC., a species of Porto Rico, from 
which it is certainly distinct. 
Erythroxylon mexicanum H. Bb. K. Nov. Gen. & Sp. 5: 178. 1821. 
I have not seen the type of £2. mexicanum, which came from Chilpancingo, South 
Mexico, but among the several species which have recently been collected in Mexico 
my no. 1477 seems to answer the description best. My specimens are characterized 
by thickish leaves, finely reticulated above, and very short petioles hardly longer 
than the stipule. It comes from near sea level, having been collected at Acaponeta, 
Tepic, June 26, 1897. 
Erythroxylon pallidum Rose, sp. nov. 
Shrubs, glabrous; branches slender, dark brown; leaves oblong, 2 to 3 em. long, 
12 to 20 mm. broad, rounded or barely retuse at apex, rounded or slightly narrowed 
at base, pale on both sides; petioles 4 to 6 mm, long; stipules ovate, scarious on the 
margins; peduncles 2 or 3mm, long; calyx lobes ovate, obtuse. 
Collected by J. N. Rose on the hacienda of San Juan Capistrano, Zacatecas, August 
18, 1897 (no, 2416, type) and August 22, 1897 (no. 2481). 
Erythroxylon pringlei Rose, sp. nov. 
Shrub, 3 meters or more high, glabrous; branches slender, dark, densely covered 
with small lenticels; leaves 1.5 to 3 em. long, 10 to 17 mm. broad, obtuse or sometimes 
slightly retuse, cuneate at base; petioles 4 to 7 mm. long, terete; stipules ovate, 
acute; fruit axillary, solitary, on reflexed peduncles, oblong, 7 mm. long, red, 
slightly glaucous. 
Collected by C. G. Pringle on mountains about Iguala, Guerrero, October 5, 1900 
(no. 8406). 
While probably near /. mevicana H. B. K., it appears to be specifically distinct. 
MELIACEAE. 
A NEW SPANISH CEDAR’ FROM CENTRAL MEXICO. 
Cedrela saxatilis Rose, sp. nov. 
A small tree, 4 to 7 meters high, with slender trunk and smooth reddish bark; 
bark of the first-year branches brown, glabrous; bud scales hairy; leaves large, the 
upper ones with rachis 20 to 80 em. long; leaflets 10 to 14, broadly lanceolate, 10 to 
15 em. long, 5 to 6 em. broad at widest point, rounded at base, strongly acuminate, 
very slightly pubescent; inflorescence a large branching panicle, 30 cm. or more long, 
bearing many flowers; pedicels short and stiff about 1 mm, long, glabrous; calyx 
glabrous, its lobes short and obtuse; corolla 6 mm. long, densely appressed-pubescent 
without, glabrous or nearly so within, the lobes somewhat purplish, column about 2 
mm. long, reddish, much longer than the ovary; stamens 5, the filaments slender, 
2mm. long; style 3 mm. long; stigma projecting from the mouth of the corolla; fruit 
2 em. long, 5-celled, filled with winged seeds. 
Collected on the pedregal near Cuernavaca, Morelos, September 10, 1903, by J.N. 
Rose and Jos. H. Painter (no. 6950, type) and by C. G, Pringle (no, 11805). 
The two collections here referred to came from the same tree. The tree was found
