Lupinus simulans Rose, sp. nov. 
Stems low, branching, with short somewhat spreading pubescence, very scant 
below; leaflets 38 to 6, oblanceolate, 1 to 3 em. long, obtuse, shortly mucronate, 
cuneate at base, green and with scanty long upwardly appressed hairs, paler and 
more hairy beneath; petioles shorter than the leaflets; stipules minute, on the upper 
leaves at least 1 to 3 mnv. long; flowering racemes short, 5 to 10 em. long, with few 
scattered flowers; bracts setaceous, 2 to 3 mm. long; pedicels 5 to 6 mm. long; calyx 
with scanty appressed pubescence, 2-lipped; lower lip a little longer than the upper, 
7 to 8mm, long, acute; upper lip 6 to 7 mm. long, 2-toothed at apex; keel ciliate; 
immature pods very hairy. 
Collected by E. W. Nelson, 18 miles southwest of Oaxaca City, September, 1894, 
(no. 1357, type) and by Charles L. Smith on Sierra de Clavellinas, Oaxaca, October, 
1894 (no. 330). 
This species is quite unlike any of the other Mexican species. It very much 
resembles in habit Crotalaria lupulina H. B. kK. 
Lupinus vernicius Rose, sp. nov. 
Perennial, 50 to 60 cm. high, softly pubescent and slightly pilose; stipules small, 
linear; leaflets 5 to 7, oblong, 2 to 4 em. long, nearly glabrous above, a little hairy 
beneath; raceme very short-peduncled; flowers verticillate; verticels distant; bracts 
caducous, silky; pedicels 2 or 3 mm. long; calyx 2-lipped; upper lip 3 mm, long, 
retuse; lower lip entire, 6 to 7 mm. long; keel ciliate; pods ascending, silky.

FOUR NEW SPECIES OF INDIGOFERA. 
Indigofera micheliana Rose, sp. nov. 
Stems herbaceous; leaflets 15 to 17, opposite, oblong, rounded at apex and cuspi- 
date, somewhat cuneate at base, appressed-pubescent on both sides, 10 to 20 mm, 
long; racemes shorter than the leaves; pods reflexed, straight, 10 to 12 mm. long, 
flattened, pubescent, .few-seeded. 
Collected by Enrique Th. Heyde in Guatemala, 1892 (no. 198), and perhaps also 
no. 38755 of Heyde & Lux as distributed by Capt. John Donnell Smith. This latter 
plant Micheli states is probably new, but he does not describe it on account of the 
poor quality of his material. 
Indigofera jaliscensis Rose, sp. nov. 
Probably shrubby; branches channelled, clothed with an appressed whitish 
pubescence; leaflets about 21, oblong, rounded at base and apex, appressed-pubescent 
on both sides, 8 to 15 mm. long, mucronate; stipules filiform, 4 to 6 mm. long; leaf 
rachis strongly channelled; racemes much elongated, 20 em, long, much longer than 
the leaves; flowers not seen; fruit small, spherical, one-seeded, 
Collected by Dr. E. Palmer near Rio Blanco, State of Jalisco, 1896 (no, 596), and 
distributed as J. sphaerocarpa, from which it differs in having the leaflets more 
numerous, pubescent upon the upper surface, rounded and not cuneate at base, the 
racemes much more elongated, the fruit smaller, ete. 
Indigofera conzattii Rose, sp. nov. 
Low shrubby plant; branches covered with closely appressed hairs, some brown 
and some white; leaflets 4 to 8 pairs, opposite, pubescent on both sides, greener 
above, 10 to 15 mm. long, oblong, rounded and apiculate at apex, rounded or broadly
