ROSE—MEXICAN AND CENTRAL AMERICAN PLANTS. 309 
6 or 8, oblong, 3 to 5 em. long, green or nearly glabrous above, pubescent beneath; 
stipules linear; raceme short-peduncled; bracts persistent even after the flowers have 
fallen; pedicels very short; calyx 2-lipped; the lips nearly equal, the upper one broad 
and barely notched. 
Collected by J. N. Rose and Walter Hough on mountains above Real del Monte, 
Hidalgo, June 2, 1899 (no. 4476). 
This species has the habit of L. compactiflorus Rose, but has different. pubescence, 
more persistent bracts, ete. 
Lupinus potosinus Rose, sp. nov. 
Stems perhaps tall, branching, the branches ascending, slender, somewhat pubes- 
cent with upwardly appressed hairs; stipules small, the free tips linear; petioles 
slender, 3 to 5 em. long; leaflets 6 to 9, oblong to broadly spatulate, 2 to 3.5 em. 
long, obtuse, green and only slightly hairy above, pale and somewhat hairy beneath; 
inflorescence on a slender peduncle, 10 to 15 em. long, rather open and the flowers 
somewhat verticillate; bracts ovate, acute; pedicels rather slender; calyx 2-lipped; 
the upper lip 2-toothed, erect, 3 min. long; the lower lip spreading, entire; pods 
spreading, 38cm. long; seeds mottled. 
Collected by Dr. E. Palmer at Alvarez, State of San Luis Potosi, September 28 to 
October 3, 1902 (no. 191, type) and in 1878 (no. 130). 
The latter number distributed as Parry and Palmer’s no. 130 was mentioned by 
Mr. Hemsley in the Biologia as a doubtful L. eytisoides. 
Lupinus pringlei Rose, sp. nov. 
Perennial, erect, herbarium specimen 30 cm. long, but entire plant doubtless much 
taller; pubescence of two kinds, one of short soft somewhat matted hairs, the other 
of long silky spreading hairs; petioles slender, longer than the leaflets; stipules 1.5 
to 2em. long, somewhat inflated at base, united with the petiole for about one-third 
its length, the free parts attenuate and spreading from the petiole; leaflets 6 to 8, 
oblanceolate, broadest just below the apex, acute, 3 to 5 em. long, glabrous above, 
silky beneath; inflorescence short, loosely flowered; pedicels very short (1 to 2mm. 
long); bracts setaceous, 8 to 10 mm. long; calyx 2-lipped; upper lip 5 mm. long, 
deeply notched; lower lip entire, 8 mm. long; pods ascending, hairy. 
Collected by C. G. Pringle at Eslava, Valley of Mexico, May 21, 1901 (no. 9538, 
type) and by Bourgeau at San Angel, same valley, 1865-6 (no. 88). 
Lupinus reflexus Rose, sp. nov. 
Undoubtedly perennial and probably branching; branches closely pubescent and 
slightly pilose; stipules rather prominent, 2 em. long, the free parts elongated; leaf- 
lets 7 to 9 oblong, 3 to 4 cm. long, mucronate, nearly glabrous above, hairy beneath; 
inflorescence at first a very dense subsessile raceme; bracts lanceolate, acuminate, 
strongly reflexed even among the flower buds, tardily deciduous; pedicels densely 
lanate; calyx deeply 2-lipped; the upper lip broad, slightly notched, 7 mm. long; 
lower lip narrower than the upper, 8 mm. long, entire; calyx tube bearing 2 bract- 
lets near the base; Keel slightly ciliate; pods hairy; seeds dark, mottled. 
Colleeted by M. E. Jones on the Voleano of Colima, Jalisco, July 13, 1892 (no.204). 
Lupinus splendens Rose, sp. nov. 
Perennial, tall and much branched, softly pubescent; petioles (of the upper leaves 
at least) shorter than the leaflets; stipules filiform, 10 to 12 mm. long; leaflets oblong, 
2 to dem. long, acute and apiculate, nearly glabrous above, silky-pubescent beneath; 
peduncles either wanting or 3 to 5 em. long; racemes 10 to 15 em. long, in fruit even 
longer; bracts very conspicuous in the bud, elongated, filiform; pedicels very pubes- 
cent; calyx strongly 2-lipped; lower lip 9 mm. long; upper lip rather broad, 6 mm. 
long, faintly retuse at apex; keel very slightly ciliate; pods 3 to 3.5 em, long, yellowish- 
pubescent; seeds dark, mottled,
