face finely pubescent and darker colored, elliptical or oblong, rounded at 
both ends, mucronulate: flowers purple, in racemes 2—3 cm long; pedicels 
1—5 mm long; calyx lobes 2 cm long; vexillum 18 mm long and nearly 
as wide, equalling in length the wings and keel; ovary glabrous. 
Height of plant unknown, and no mature legumes accompany the

Mexico: Collected near Tehuacan Puebla, June, 1905. 
10. Sophora Purpusi T. S. Brandegee, |. c., p. 235. 
Fruticose, young growth densely white-pubescent, becoming darker 
with age: leaves crowded, 3—4 cm long; petioles 5—7 mm long; rachis 
tomentose; leaflets coriaceous, 6—9 pairs and a terminal one, ovate-oblong, 
rounded at both ends, nearly sessile, 6—8 mm long, 3—4 mm wide, 
appressed, white silky-hairy beneath, darker and less hairy above; stipules 
small, subulate: flowers terminating the branches in a very short raceme, 
white, purple-tinged or dotted; pedicels 3 mm long, bearing minute 
bracteoles close to the calyx; calyx 1 cm long, campanulate, narrowed 
at the base about the disk, silky-hairy; the three teeth of the lower part 
deltoid-acuminate, 1 mm long, the upper part broad and slightly longer: 
vexillum broadly obovate, 2 cm long, exceeding the oblong wings and 
keel: stamens united !/, their length: legume 8 cm long, 1 em wide, 
aeuminate, silky-hairy, 2—5 seeded; stipe shorter than the calyx. 
The seeds are young, but probably even at maturity the pod would 
be flattened. 
Mexico: Collected on Sierra de Parras, Coahuila, March, 1905. 
11. Halenia Purpusi T. S. Brandegee, l. c., p. 235. 
Perennial, glabrous; leaves radical, 3-nerved, spatulate, 3—5 em long 
including the long petiole, 5—7 mm wide, obtuse or acuminate: stems 
2- 3 dm high, bearing rarely a pair of short, linear leaves or bracts near 
the middle and a few setaceous bracts at the inflorescence: flowers 3—4 
terminating the stem; pedicels 4—7 mm long: sepals oblong, acuminate, !/, the 
Jength of the mature corolla: corolla white, 7 mm long; spur very short or 
rudimentary: capsule exserted !/, its length and slightly curvednear the tip. 
The general appearance of this plant is very much like that of H. 
plantaginea, but the flowers are smaller and lack the long spurs. 
Mexico: Collected on Ixtaccihuatl, growing in meadows above timber- 
line. No. 1760. 
12. Marsdenia parvifolia T. S. Brandegee, 1. c., p. 235. 
Frutescent, the slender stems not climbing, slightly pubescent in 
lines: leaves glabrous, ovate-oblong, acuminate, cuneate at base, 1—2 cm 
long, 4—7 mm wide; petiole 2 mm long: flowers on pedicels 2 mm long, 
1—2 from the axils of the leaves: calyx parted nearly to the base into 5 
ovate-lanceolate lobes 3 mm long; corolla campanulate, deeply parted into 
ligulate lobes that slightly exceed the calyx: scales of the corona distinct, 
longer than the inflexed tips of the anthers and shorter than the 2-lobed 
stigma: fruit unknown. 
Mexico: Collected near Tehuacan, Puebla, on rocks. No. 1325.
