ROSE—MEXICAN AND CENTRAL AMERICAN PLANTS. 307 
to 10, oblong, 2 to 8 cm. long, densely hairy beneath; stipules linear with pubescence 
like that of the stem; racemes subsessile, compact; bracts linear, much longer than 
the very short pedicels; calyx 2-lipped, the lower lip only a little longer than the 
upper; upper lip notched; keel not ciliate; fruit not seen. 
Collected by J. N. Rose near Tultenango Canyon, State of Mexico, July 138, 1901 
(no. 5430). 
Lupinus geophilus Rose, sp. nov. 
Perennial, the stems prostrate on the ground often forming a dense mat, densely 
pilose-pubescent; stipules small, united with the petiole for one-third their length, 
the free parts linear to narrowly lanceolate, green; petioles pilose; leaflets 7 or 8, 
glabrous above, slightly pilose beneath, 1 to 2 cm. long, obtuse; inflorescence a very 
short spike-like raceme, 10 cm. or less long, sessile or subsessile; bracts narrow, con- 
spicuous in the young raceme, longer than the pedicels but not extending beyond the 
developed calyx; calyx pubescent, 2-lipped; upper lip 38 mm. long, deeply notched, 
lower lip entire, 6 mm. long; banner 10 to 12 mm. long; pods spreading, pubescent 
with long yellowish hairs. 
Collected by J. N. Rose and Jos. H. Painter at Cima, in the State of Mexico, Sep- 
tember 19, 1903 (no. 7160, type), and in the upper slopes of Nevada de Toluca, Octo- 
ber 15 and 16, 1903 (nos. 7908, 7967, and 7969). 
In habit very unlike any other species of central Mexico. 
Lupinus chiapensis Rose, sp. nov. 
Perennial, [20 to 180 cm. high, more or less branching, glabrous or at least glabrate 
below, with short, somewhat scanty appressed pubescence above; leaflets 4 to 7, 
oblong, 1.5 to 3.5 em. long, obtuse, shortly mucronate, green and glabrous above, 
but with scanty appressed pubescence beneath; stipules small, free nearly to the 
base; racemes elongated, 10 to 20 cm. long; flowers subverticillate; bracts seta- 
ceous, small; pedicels short, 2 to 8 mm. long; calyx appressed-pubescent, 2-lipped; 
lower lip 4 mm. long, twice as long as the upper; upper lip short, 2-toothed; bract- 
lets at base of calyx; pods narrowly oblong, 3 to 4 cm, long, in the immature state 
hairy. 
Collected by E. W. Nelson near San Cristobal, Chiapas, September 18, 1895 (no. 
3199). 
Lupinus confusus Rose, sp. nov. 
A low rather spreading plant, nearly glabrous; leaflets 6 to 8, linear, somewhat 
narrowed at base, obtuse, green and glabrate above, only slightly hairy beneath, 2.5 
to 6 em. long, at most 5 mm. wide; petioles elongated, longer than the leaflets; stipules 
small, united with the petiole for more than half their length, free parts setaceous; 
bracts narrowly lanceolate, long-acuminate, caducous; flowers in’ subverticillate 
racemes; calyx with scanty appressed pubescence, two-lipped; lower lip acute, entire, 
5 mm. long, upper strongly 2-toothed, 4 mm. long; bractlets minute, borne at the 
mouth of the calyx; keel ciliate; pods narrow; 3 cm. long, 3 to 5-seeded, cuneate at 
base, acuminate. 
Collected by C. G. Pringle in the Sierra Madre, State of Chihuahua, October 5, 
1887 (no. 1205) and distributed as L. ehrenbergi. It differs considerably, however, 
from that species, especially in leaflets, pubescence, calyx, ete. 
Lupinus giganteus Rose, sp. nov. 
Perennial with tall branching stems with only scant appressed pubescence; stipules 
small, united with the petiole for half their length, the free parts setaceous; leaflets 
6 to 8, oblong, green and slightly hairy above; racemes subsessile, elongated, 60 to 
80 em. high, many-flowered; pedicels slender, 1 cm. long, with 2 branchlets near 
the middle; bracts lanceolate, long-attenuate, much longer than the buds, early 
deciduous; calyx 2-lipped, both lips entire; lower lip narrow, 9 mm. long, strongly 
nerved; upper lip 6 to 7 mm. long, broad, acute; ovary densely pubescent; old pods 
nearly glabrous,
