WOOTON AND STANDLEY—NEW PLANTS FROM NEW MEXICO. 139 
apex; racemes rather densely many-flowered, long-peduncled, about 5 cm. long; 
flowers sessile; calyx angled, glabrous, straw colored, with a few pellucid, yel- 
lowish glands, the lobes lanceolate, green, attenuate, silky-pubescent along the 
margins; corolla rose purple, about 8 mm. long; stamens 6; fruit glabrous, 3.5 
mm. long, semiorbicular in outline. 
Type in the U. 8. National Herbarium, no. 370697, collected near Albuquerque 
in 1909 by Winnie Harward (no. 17). 
ADDITIONAL SPECIMENS EXAMINED: Near Belen, August 1, 1906, Wooton. 
This is so unlike all other species of the genus that it can scarcely be confused 
with any. The habit alone is sufficient to distinguish it. In general appearance 
it much more closely resembles certain species of Parosela, but the structure of 
the flower and number of stamens makes it impossible to place it with them. 
Phaseolus dilatatus Wooton & Standley, sp. nov. 
Perennial from a thickened root; stems long, slender, twining, glabrous or 
sparingly puberulent; stipules small, lanceolate; petioles slender, equaling or 
longer than the leaflets, these linear-lanceolate to triangular-ovate, entire, or 
dilated and with 2 small rounded lobes at the base, obtuse, bright green, scaberu- 
lous, ciliolate; peduncles slender, somewhat exceeding the leaves, 5 to 12 em. 
long; pedicels 4 mm. long or less, sparingly puberulent; calyx puberulent, with 
rounded lobes; bracts minute, elliptic-oblong; corolla 10 to 12 mm. long; pods 
about 20 mm. long and 5 mm. broad, stout, slightly curved, nearly glabrous, with 
a slender style 1.5 mm. long. 
Type in the U. S. National Herbarium, no. 138616, collected in the Mogollon 
Mountains August 30, 1881, by Dr. H. H. Rusby. Another specimen is in the 
herbarium of Dr. E. L. Greene, collected in the Burro Mountains in June, 1881, 
by Doctor Rusby. 
This suggests P. grayanus, but the leaflets are not lobed as in that species, 
the peduncles are shorter, the pod is nearly glabrous ana smaller, and the style 
is long and slender. 
Phaseolus grayanus Wooton & Standley, sp. nov. 
Phaseolus wrightit A. Gray, Pl. Wright. 2: 33. 1853, not A. Gray, op. cit. 
1: 438. 1852. 
Perennial with long, slender, climbing stems, these sparingly puberulent; 
stipules small, triangular-lanceolate; petioles one-half to two-thirds as long as 
the leaflets; leaflets deeply 3-lobed, at least the terminal one, the lobes narrowly 
oblong or rhombic, blunt, bright green, thin, nearly glabrous, but puberulent 
along the veins; peduncles much longer than the leaves, 10 to 25 cm. long, 
slender, glabrous or puberulent, pubescent about the flowers; flowers few, dis- 
tant, on pedicels 5 mm. long or less; calyx puberulent, the lobes broadly 
rounded, ciliate; corolla purplish, 12 to 15 mm. long; pods broad, 25 to 30 mm. 
long and 8 or 9 mm. wide, curved, densely soft-pubescent, acute, with a very 
short, stout style. 
Type in the U. 8. National Herbarium, no. 232982, collected in the San Luis 
Mountains, September 5, 1893, by Dr. E, A. Mearns (no. 2124).

The species also occurs in Arizona. 
Our plant has always been referred to P. wrightii. Doctor Gray, in Plantae 
Wrightianae, speaks of Wright’s specimen, stating that it differs from the 
Texas plant in certain particulars and that the description of that plant must 
be modified. The Texan plant, true P. wrightii, differs from ours in having
