WOOTON AND STANDLEY—NEW PLANTS FROM NEW MEXICO. 1387 
narrowly triangular-lanceolate, about 10 mm. long, adnate to the petiole, not 
connate ; leaves 10 to 18 cm. long, with about 20 pairs of leaflets, villous through- 
out with weak, spreading hairs; leaflets elliptic to ovate-lanceolate, 10 to 12 
mm. long, narrowed at the apex, acute, entire, glabrate above; flowers in 
elongated, several to many-flowered racemes 15 to 25 cm. long (including the 
peduncles) ; bracts linear-lanceolate, twice as long as the ascending pedicels 
(these 2 or 3 mm. long); calyx campanulate, slightly gibbous above, 7 to 9 
mm. long, the subulate teeth about one-third as long, pubescent with black and 
white, loosely appressed hairs, the black ones more noticeable on the buds; 
corolla purple, about 20 mm. long, the banner and wings considerably surpassing 
the rounded keel; mature fruit not seen; very young pods 1-celled, several- 
seeded, thick-walled, terete, neither suture intruded, densely appressed-pubescent. 
Type in the U. S. National Herbarium, no. 690254, collected in James Canyon 
in the Sacramento Mountains near Cloudcroft, Otero County, July 23, 1899, by 
E. O. Wooton. Altitude about 2,550 meters. 
We hesitate to describe this species for which the mature fruit is lacking, 
but it is so distinct from anything else we have seen that the description is 
given and a name applied merely as a means of recording the plant. 
Lupinus argillaceus Wooton & Standley, sp. noy. 
Low annual of the Platyecarpos group; stem about 10 cm. high, with numerous 
lateral divaricnte branches as long or longer; whole plant softly silky villous, 
the pubescence being somewhat appressed and thus not conspicuous ; petioles 3 
to 5 em. long: leaflets 5 to 7, 1 to 2 em. long, oblanceolate, obtuse or acute, about 
equally pubescent on both sides; flowers few, in contracted, head-like clusters 
at the ends of peduncles mostly shorter than the petioles of the adjacent leaves, 
with broadly ovate-lanceolate bracts 3 or 4 mm, long; calyx similar to that of 
L. kingii, the upper lobe deeply 2-cleft, the divisions lanceolate, acute, the 
lower lobe minutely 8-toothed at the apex, the toothing more or less obscured 
by the pubescence in dried material, the upper lobe about two-thirds as long as 
the lower, with minute bracts at the sinuses between the two lobes; corolla 
blue or white, the banner narrowly ovate, reflexed, shorter than the wings and 
the elongated, rather straight keel; stamens monadelphous, the lower five an- 
thers linear, almost as long as their filaments, the upper anthers minute; ovary 
with 2 ovules: fruit a short, rhombic-ovate, 2-seeded legume; seeds almost 
rotund, lenticular, whitish, without markings. 
Type in the U. S. National Herbarium, no. 498990, collected near Pecos, San 
Miguel County, at an altitude of 2,010 meters, August 17, 1908, by Paul C. 
Standley (no. 4974). The plants grew on the low hills about Pecos, especially 
in the deep gullies, in a heavy red clay soil. 
ADDITIONAL SPECIMENS EXAMINED: Near Pecos, alt. 2,010 meters, 1908, Stand- 
ley 4975; El Rito, August 17, 1904, Wooton. 
Standley’s specimens were distributed as ZL. kingii and are listed as that 
species in his report upon his 1908 collections in Mublenbergia.” Of the two 
numbers collected in the same locality one had white flowers and the other blue. 
Lupinus laetus Wooton & Standley, sp. nov. 
A slender perennial with few spreading or ascending branches; stems finely 
and sparingly appressed-pubescent ; petioles slender, about as long as the leaf- 
lets, these elliptic-oblanceolate, 45 to 60 mm. long, obtuse, mucronate, bright 
green and glabrous above, with a few scattered, appressed hairs beneath; 
raceme 15 to 20 cm. long, loosely few-flowered, «short-pedunculate; pedicels 
slender, ascending, 8 mm. long, sparingly pubescent ; calyx sericeous, the lobes 
about equal, broad, rather obtuse; corolla 12 mm. long, bright blue; fruit not 
seen.
