1388 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Type in the U. 8S. National Herbarium, no. 562219, collected at Winter Folly 
in the Sacramento Mountains north of Clouderoft, August 18, 1899, by E. O. 
Wooton. Altitude about 2,700 meters. 
The plant is of the group of L. plattensis, but its bright blue flowers at once 
distinguish it. 
Lupinus aquilinus Wooton & Standley, sp. nov. 
A much branched, suffrutescent perennial, 60 to 150 cm. high; stems slender, 
spreading, sparingly and finely sericeous; petioles slender, about equaling the 
leaflets, these elliptic-oblanceolate, 35 to 45 mm. long, obtuse, mucronate, gray- 
ish green, glabrous above, finely sericeous beneath; racemes on short peduncles, 
dense, 5 cm. long or less, few-flowered; pedicels ascending, stout, sericeous, 4 
min. long; calyx densely sericeous, scarcely gibbous, the two lobes almost equal, 
rather broad, acute, entire; corolla 12 mm. long, pale bluish and yellowish, 
the banner with a dark spot; pods 80 mm. long and 8 mm. wide or less, 3 or 
4-seeded ; seeds 4 mm. long, greenish gray, finely splashed with dark green. 
Type in the U. S. National Herbarium, no. 562095, collected at Gilmores 
Ranch, on Eagle Creek, in the White Mountains, August 25, 1907, by E. O. 
Wooton and Paul C. Standley (no, 3613). Altitude 2,220 meters.

This is a grayish plant with numerous slender, spreading branches. It is 
rather abundant about Gilmores Ranch, growing on slopes in the shade of 
pines. It is of the L. plattensis group and is related to L. sierra-blancae, which 
grows not faraway. It is a lower plant, however, than L, sierrae-blancae, with 
more branches, fewer flowers, and shorter, obtuse leaflets. 
Lupinus sierrae-blancae Wooton & Standley, sp. nov. 
A tall perennial, 1 meter high or more, much branched: stems stout and 
somewhat succulent, finely white-pubescent, the pubescence loose; petioles 
equaling the leaflets, these 7 to 9, 50 to 70 mm. long, linear-elliptic, very acute, 
attenuate to the base, yellowish green, glabrous above, finely strigillose 
beneath or almost glabrous; racemes long (25 to 30 cm.), many-flowered, rather 
loose; pedicels divergent, stout, 10 mm. long, densely pubescent -with short, 
spreading hairs; calyx slightly gibbous, loosely pubescent, the upper lip 
longer than the lower, both narrow, entire, attenuate; corolla 12 mm. long, 
dull bluish tinged with yellow, the banner with a large darker spot; pods 
ascending, stout, 85 mm. long and 35 mm. wide or less, densely hirtellous, 
5 to 7-seeded; mature seeds not seen. 
Type in the U, S. National Herbarium, no. 562220, collected on the lower 
part of White Mountain Peak, July 6, 1895, by E. O. Wooton. Altitude 2,340 
meters, 
ADDITIONAL SPECIMENS EXAMINED: Gilmores Ranch, on Eagle Creek, July 14, 
1895, Wooton; Gilmores Ranch, July 29, 1901, Wooton; Ruidoso Creek, July 5 
1895, Wooton. 
The plant is known only from the open meadows or parks which are so 
numerous on the timbered slopes of White Mountain Peak. The largest of 
our New Mexican lupines, it is a conspicuous feature of the vegetation where 
it occurs. While related to L. plattensis, it may be distinguished by its larger, 
acute leaves and the much larger size of the plants. 
Petalostemum prostratums Wooton & Standley, sp. nov. 
Stems slender, prostrate, 60 cm. long or less, glabrous, with numerous orbicu- 
lar, reddish brown glands; leaves long-petioled, the leaflets mostly 7, glabrous, 
glaucous, glandular-dotted, cuneate-oblanceolate, nearly sessile, rounded at the
