ROSE—MEXICAN AND CENTRAL AMERICAN PLANTS. 47 
Crotalaria viminalis Rose, sp. nov. Puare VI. 
A tall shrub, 1.8 to 5 meters high with long pendant branches giving the habit of 
a weeping willow, covered with white soft somewhat spreading pubescence; leaflets 
3, oblong, rounded or somewhat narrowed at base, obtuse, glabrous or nearly so 
above, soft silky pubescent beneath, 2 to + cm. long; stipules minute; racemes 
elongated and hanging, 3 to 10 dm. long, naked toward the base, many-flowered; 
bracts subtending flowers linear; pedicels 5 to 6 mm. long; calyx 1 em. long, the 
tube short, the lobes acuminate, silky; banner broad, about 15mm. long; keel about 
2 mm. long, bent at the middle nearly at right angles, ciliate on the upper and 
lower margins; wings much shorter; stamens glabrous; stvle slender, hairy below, 
glabrous near the middle, hairy on one side above; pods 3 em, long, silky. 
A common plant on the exposed lava beds near Cuernavaca, altitude 1,660 meters. 
The long pendent branches waving made it a most striking plant. 
Collected by Mr. C. G. Pringle at Cuernavaca, September, 1896 (no. 6557), and. 
same locality by J. N. Rose, May, 1899 (no, 4541, type). 
The writer first took this species for the (. eriocarpa Bentham, but he has since 
collected, perhaps at the very type locality, the latter species. (C. eriocarpa comes 
from a totally different floral zone, has short racemes and a yellowish pubescence, ete.

Indigofera platycarpa Rose, sp. nov. Puiatre VII. 
A shrub 3 to 5 m. high, much-branched; branches whitish-pubescent or in the 
younger parts reddish; leaflets mostly 17 to 21, opposite, petiolulate, oblong to obovate, 
rounded at base, rounded or retuse at apex and with a very decided apiculation, 
appressed-pubescent on both sides, + to 8 mm. long; racemes axillary, much shorter 
than the leaves, few-flowered; calyx very small (1 mm. high) cup-shaped; corolla 
7mm. long, rustv-pubescent; pod broad for the genus, flat, 2 to 3 cm. long, shghtly 
pubescent; seeds few. 
Collected by C. G. Pringle on mountains above Iguala, Guerrero, October 6, 1900 
(no. 8399), 
This species is characterized by its very broad pods.

Lupinus submontanus Rose, sp. nov. Puare VIII. 
Rather low plants, 3 to 6 dm. high, somewhat branching, glabvate below; leaflets 
4+ to 8, mostly 7 or 8, narrowly oblanceolate, 3 to 4 em, long, obtuse, glabrous, 
slightly hairy beneath, longer than the slender petiole; stipules small, united for 
half their length to the petiole, free tips setaceous; bracts linear, 5 to 6 mm. long; 
flowers small, in a short (1 dm. long in type specimen) raceme, spike-like, pedicels 
1mm. long canescently pubescent as are also rachis and calyx; calyx 2-lipped; lower 
lip 5 mm. long, twice as long as upper, obtuse, perhaps sometimes 3-toothed; upper 
lip strongly 2-toothed: keel ciliate; fruit not seen. 
Collected by C. G. Pringle on Mount Orizaba, August 26, 1901 (no. 8544), and by 
J. N. Rose and Robert Hay, same date and place (no. 45675, type). 
This species is quite unlike any other known Mexican species. In the toothing of 
the lower lip it answers to the little known L. mewicanus, but in other respects differs. 
Of the three or four species which have been reported from Mount Orizaba it seems 
quite distinct. It might be suspected to be L. glabratus Mart. & Gal. from near the 
same station, but it certainly does not answer the description of that species.

c, lower calyx lobe. Figs a and d, natural size, bande scale of 3.
