Micranthi. "n 278 
flexuous, with internodes nearly as long as leaves, decumbent at 
base and with peduncles in the middle axils. Blooming evidently 
in July and fruiting in September and with peduncles in the upper 
axils, but the type gathered in October after the tops had a second 
growth from the fall rains after fruiting. Near Chapala Jalisco 
Mex., Oct. 5, 1903. J. N. Rose, Nat. Herb. No. 451239. 
255. Astragalus hypoxylus Watson Proc. Am. Acad. 18 192 
(1883). Pods about 1 cm. long and 3 mm. wide and high, obliquely 
and narrowly linear-oblong, with ventral suture about straight or 
a trifle concave, shortly acuminate into a triangular beak about 2 
mm. long which is straight with the ventral suture, inclined to be a 
little laterally flattened, ascending, cross section cordate, rather. 
narrowly sulcate dorsally, ashy. Banner about 3-4 mm. long, 
oval, abruptly erect at end of tube. Wings oblong, about as long 
as banner and 2 mm. longer than keel. Keel about 2 mm. long 
and high, erect and deltoid, acutish. Calyx tube turbinate, about 
2 mm. long, tapering into the slender but very short pedicel, ni- 
grescent, with subulate teeth as long as tube and lax. Bracts mi- 
nute, about as long as pedicels. Peduncles about 5 cm. long, from 
the lower axils, twice as long as leaves. Leaves 2-3 cm. long, all 
short-petioled, spreading.  Leaflets 4-6 pairs, oval-obovate and long- 
petiolulate, rounded, ashy with fine and appressed hairs.  Stipules 
not connate, small, green, triangular. Stems loosely matted, a few 
inches long, with short internodes. Huachuca Mts. Arizona, Lemmon. 
Purpus's No. 2477 from Esperanza Puebla seems to be the same. 
Plants referred to this from Lower California seem different. 
Astragalus Purpusi Jones might be sought here, but has a 
stipitate pod. 
256. Astragalus Hartwegi Benth. Pl. Hartw. 10 (1839). Pods 
2-3 mm. wide, about 2 mm. high, with reniform cross section, often 
a little sulcate ventrally as well as dorsally, appearing as if a 
trifle inflated, densely spicate and very closely reflexed, minutely 
stipitate. Flowers white or purple, closely reflexed. Banner nearly 
round, closely hugging the keel or abruptly arched to 45? beyond 
the calyx tips, rather thick and with sides barely reflexed around 
the margin, about 3 mm. long, about 1 mm. longer than wings. 
Wings linear, a little arched, about 1 mm. longer than keel. Keel 
with straight base and then abruptly erect, obtuse, the general out- 
line faleate-obovate, about 2 mm high. Calyx tube campanulate, 
about 2 mm. long, very oblique at both ends and attached on the 
lower corner, nigrescent, the deltoid teeth about half as long as 
tube. Fruiting pedicels hardly 1 mm. long and about as long as 
the hyaline bracts. Peduncles 5-20 cm. long, subterminal, rather 
stout, much longer than the leaves, rarely some lower ones short. 
Floral spikes shorter than the peduncles. Leaves rarely 5 cm. long, 
the upper sessile. Leaflets 5-9 pairs, not contiguous, narrowly ob- 
long, obtuse, rather smooth above, 5-15 mm. long, cuneate at base, 
those of the lower leaves much reduced and often oval. Stipules 
not connate, lanceolate, rather large, green.  Internodes shorter 
than the leaves. Stems slender ascending, a foot or two long, flexu- 
ous, branched below, from an erect and rather slender root. Pu- 
bescence short and closely appressed. Central Mexico, and north- 
ward probably to Chihuahua. Lower Temperate life zone.
