ROSE—MEXIVAN AND CENTRAL AMERICAN PLANTS. 3813 
Type collected by J. N. Rose and Jos. H. Painter at Toluca, September 4, 1908 
(no. 6778). 
This species seems to be common in Central Mexico, as several specimens collected 
or seen by the writer in the Valley of Mexico and elsewhere seem referable here. 
Crotalaria gracilenta Rose, sp. nov. 
Perennial with frutescent base, much branched, 30 to 40 em. high, pubescent; leaf- 
lets 3, linear to oblong-linear, 2 to 6 em. long, 2 to 5 mm. broad, glabrous above, 
pubescent beneath; racemes | to 2 cm. long, rather few-flowered; pedicels slender, 5 
to 6 em. long, minutely bi-bracteolate near the middle; calyx 6 mm. long; banner 
8 mm. long; wings 7 mm. long, oblong; keel strongly beaked; pods appressed-pubes- 
cent, stipitate. 
Solleeted by J. N. Rose and Jos. Hf. Painter near Etzatlan, Jalisco, October 2, 
1903 (no. 4570, type) and by C. G. Pringle, same station, October 23, 1903 (no. 11893). 
Close to (. lenwissima, but leaves not nearly so attenuate, flowers smaller, pubes- 
cence of pedicels and calyx softer, racemes laxer, ete. 
Harpelyce” goldmani Rose, sp. noy. 
Probably a low shrub; bark of second-year twigs light-colored, glabrous; young 
branches densely pubescent; stipules linear, caducous; leaflets opposite, 5 to 9 pairs 
and an odd one, oblong, obtuse, glabrous above, densely pubescent and glandular 
beneath; inflorescence dense-flowered, 10 cm. or more long, the short peduncle and 
rachis densely pubescent with short brown spreading hairs; calyx deeply 2-lipped, 
densely reddish-pubescent; young pods and long styles glabrous. 
Collected by EK. A. Goldman at Canjob, Chiapas, Mareh 27, 1904 (no. 787). 
This species is near //. pringles, but the leaflets, even the very youngest, are glabrous, 
Rhynchosia cuernavacana Rose. 
Rhynchosia australis Rose, Contr. Nat. Herb. 8: 48. 1903, not Benth, 1864. 
Willardia parviflora Rose, sp. noy. 
Small shrubs, 3 to 4 meters high, much branched; stipules broadly ovate, minute 
(1 mm. or less long), caducous; leaves when young denscly pubescent, in age glab- 
rate above, slightly pubescent, beneath, 5 to 10 pairs, oblong, 8 to 161mm. long, 
rounded at apex, thickish, the margin revolute; flowers borne in slender racemes, 
usually appearing before the leaves; racemes at first clustered in the axils of old 
leaf sears but really borne on the young branches and in age somewhat separated; 
pedicels short, bracteate; calyx pubescent, broadly tubular, short (2 mm. long), the 
three lower teeth small, approximate, the dorsal lobe broad, truncate or barely 
retuse; flowers 6 to 7 mm. long; banner orbicular, retuse; keel broad; stamens 10, 
united almost to the apex into a closed tube; ventral stamen free at base; ovary and 
style glabrous, the latter hooked; pods very flat, oblong to elliptical, cuneate at hase, 
generally acute at apex, 3 to Tem, long, 1 or 2-seeded, tardily dehiscing; valves 
thin, with no internal partitions; seed 11 mm. broad, kidney-shaped. 
Collected only at Yautepec, Morelos, by C. G. Pringle in 1901 (no. 8470, type) and 
October 3, 1902 (no. 11347), and by J. N. Rose, July 5, 1901 and in 1905 (no, 6576). 
In foliage, flowers, and pods closely resembling W. merreana. 
ERYTHROXYLACEAE. 
DESCRIPTIONS OF FOUR SPECIES OF ERYTHROXYLON. 
Erythroxylon compactum Rose, sp. nov. 
Shrubs 1.5 to 3 meters high, glabrous; branches short and often spurlike, usually 
elongating slowly from year to year, often covered with the imbricating bases of old 
stipules; old bark very dark, the young bark reddish brown rather thickly set with
