Hamosi. 256 z 
at the rounded and nearly erect and purple tip. Calyx tube nar- 
rowly campanulate, about 3 mm. long, attached near the lower 
corner, the broadly triangular teeth about half as long and nigres- 
cent. Pedicels about 2 mm. long, longer or shorter than the ovate 
to triangular-subulate bracts. Peduncles 1-2 dm. long, filiform, 
rather spreading. Spikes rounded to oblong. Leaves about 1 dm. 
long, weak and lax and with tapering rachis and evident petioles 
even above. Leaflets 7-19 (mostly 10) pairs, all about the same 
' size on each leaf, the well developed ones oblong to obovate, with 
cuneate and long-petiolulate base, hardly 1 cm. long, those of the 
lowest leaves often very small and oval, usually notched. Upper 
internodes the shorter. Stems 1-2 ft. long, weak and straggling. 
Stipules rather broad, acute, green and spreading, 3-5 mm. long. 
Plants nearly smooth. From Mason Co., Ill., and eastern Kansas 
to Oklahoma and southern Texas and Mississippi on prairies and 
margins of woods. Lower Temperate life zone mostly. Blooming in 
spring. 
Astragalus distortus var. Engelmanni (Sheldon Minn. Bot. Stud. 
9 152 (1894) as species). Pods lunate, reticulated, with cross-sec- 
tion triangular-cordate, the dorsal suture intruded only as a raised 
line, coriaceous, not obcompressed, 4-5 mm. high. No. 145 E. Hall 
from open woods at Houston, Texas, in flower and fruit in April.

216. Astragalus glaber Mx. Fl. 2 66 (1803). A. apilosus 
Sheldon. Tragacantha Michauxii Kuntze.. Pods narrowly oblong to 
linear, 1.5-2.5 cm. long, 4-6 mm. high or: wide, coriaceous, acute 
‘at both ends and a little curved below, somewhat swollen in the mid- 
dle, inclined to be obeompressed when mature, shallow-suleate dor- 
sally, smooth, reticulated, not fully 2-celled the suture being in- 
truded half way, with triangular-reniform cross section. Flowers 
white, spreading to reflexed, a little over 1 cm. long, not narrow. 
Banner 6-8 mm. long, sharply arched at calyx tips to erect, about 
4 mm. longer than wings, with sides reflexed below. Wings oblan- 
ceolate, little longer than keel, about 2 mm. wide, arched 45”. 
Keel about 6 mm. long, the base a trifle convex, then abruptly erect 
and tip 4 mm. high, triangular, but obtuse, the base about 3 mm. 
high. Calyx about 5 mm. long and 3 mm. high, nearly truncate 
below and attached on the lower corner where it is a little fleshy, 
not oblique above, with broad and rounded sinuses and narrowly 
triangular teeth about 1 mm. long, hyaline. Pedicels slender, 2-3 
mm. long, rather longer than the ovate bracts. Peduncles about 
as long as leaves, the rachis as much more, slender. Leaves 6-8 
em. long, tapering, scattered (because of the slender internodes). 
Leaflets 7-18 pairs, 1-2 cm. long, linear-elliptical, thick, the lower 
ones obtuse to notched, conspicuously reduced above on the rachis. 
Stipules minute, spreading. Stems strict, very sulcate, about 2 ft. 
long. Pubescence none throughout except on the lower side of 
leaflets and calyx. North Carolina, Georgia and Florida on barrens. 
Blooming in summer. Lower Temperate life zone. 
217. Astragalus Coahuile n. sp. Pods linear-oblong, char- 
taceous, nearly straight, triangular-acute, 2-celled except at tip, 
flattened laterally, or nearly round, nearly smooth, about 1.5 cm. 
lodg and 3-4 mm. high, inclined to be sharply suleate dorsally. 
Flowers few, purplish, about 8 mm. long. Banner oval, arched 
abruptly at calyx tips to 45° or erect, 6-7 mm. long, with sides re- 
flexed 1 mm. wide below, with narrow white spot purple-veined. 
Wings lanceolate, arched to 45°, about 2 mm. longer than keel and 
4 mm. shorter than banner. Keel with straight base and then 
abruptly rounded to a little more than erect and with deltoid tip 
3 mm. high. Calyx tube about 3 mm. long, acute at base and  - 
about equally inserted, nigrescent, oblique at tip, and cleft deeper > 
above, the sinuses rather narrow, the teeth subulate and nearly as Y. 
long as tube, black. Pedicels slender 2-3 mm. long, a little longer — —
