136. A8tr«fl«lu» Salmonis Jones Cont. 8 9 (1808). Referred to 

 A. HourKovli l)y NVaisim and Oruy. Youn^ pods rather triquetrous in 

 -Ti-v s«'ctlon, in nge renifonn, weakly attached to calyx aiul sessile or 

 sipe half the calyx, abruptly contracted below, very oblitiuely oblonj;. 

 ;t.((M* 2 cm. long, 5-7 mm. wide and high, stron;rly and closely cross- 

 ribbed when fresh with the outer wall fleshy and pulpy and the inner 

 wiHxly and the cavity tilled with pulp, the septum intruded half way, 

 shallow and broadly sulcate nearly to tip and base, and canoe-shaped 

 dorsally, rounded vi nfrally and the* thick suture raised when dry but 

 not when fresh, the deltoid and very short tip about at ripht angles to 

 dorsal suture and declined, seemingly glabrous but minutely i)ubescent, 

 rarely pendt-nr, 1-.''. Flowers about 3 and loosely racemose, purple 



tinged, about 1 cm. long, broad. Banner nearly 1 cm. long, oblong- 

 oval, deeply notched, veined from the back, the midrib purple and with 

 .1 thickened groove on t ach side running two-thirds the way to tip, re- 

 sembling Frasera glands, then the thin sides are retlexed 4r)0 from th** 

 edge of the groove below but not :it tip, arched gently at end of 

 calyx to 45°, dlrty-greenish-whlte with a purple tinge. Wings broadly 

 linear. 2 mm. wide, roundetl. 8 mm. long and equaling the banner, erose. 

 not narrowed above, arched at end of keel to 45o, concealing it. about 

 flat and close-pre.ssed to it. Keel puri)le-tipped. sharply rounded 

 to about l.Sno, obtu.se, short, straight, 4 mm. shorter than wings, about 

 .'5 mm. high. Calyx 4-angled, the tube about 4 nun. long, barely wider 

 above, oblique at base by the lower corner being cut «)IT and so seem- 

 ing saccate, above, equally inserted, appressed-short-hairy and nigres- 

 cent ; teeth subulate and about half as long, a little oblique at tip. 

 Pedicels 2-4 mm. long, at least twice as long as the hyaline ovate brads. 

 Peduncles subscapose, 1-2 dm. long, rather stout, ascending 1 > erect in 

 flower and prostrate in fruit. Leaves 5-10 cm. long, very many and 

 very narrow, witJi the stout petiole about one-third the whi le. Leaf- 

 lets about 6 pairs, rather thick, 3-5 mm. long, elliptical and obtuse, mostly 

 folded and appearing linear, seemingly sharp but mostly obtuse. Stems 

 rarely 2-5 cm. long, many from a nmch branched and woody crown 

 from a thick and erect root. Whole plant puberuleiit. (Growing on dry 

 rocky ridges. Blue Sits. Oregon and vicinity. Middle Temperate life 

 zone and in flower in early spring. 



137. Astragalus obscurus Watson Bot. King G9 (1871). Pods .short- 

 racemose, shortly-acuminate at both ends, broadly linear, about 2.5 ,-m. 

 long and 3 nun. wide and high, rather trique trous-reniform in cro.ss 

 section, inclined to be a irille laterally flattened, coriaceous and a liiile 

 fleshy when fresh, not reticulated nor ribbed, both suturc^s raised ex- 

 ternally and the ventral thickened when dry, often reddish but not 

 mottled, narrowly and shallow sulcate dorsally, the dorsal suture vari- 

 ably Intruded from a mere trace to nearly the width of the cavity, 

 ashy with, clo.se pressed hairs as is the whole plant, sessile on a very 

 stout pedicel about 2 mm. long which is about as long as bract, the 

 .straight tip In line with the dorsal suture not declined. Flowers at 

 first in heads then elongating a little, less than ten, al)out 8 mm. long. 

 Banner oval, about 7 mm. long, abruptly and nearly erect from calyx 

 tips, with sides reflexed about 1 mm. wide below only, filled by the very 

 broad and large sulcus which is triangular and sharp and 2 nun. d<HM>. 

 broader at tip, with conspicuous purple stripes radiating palmately from 

 the end of the thick claw. Wings very obliquely obovate, a.scending 

 450, close pressed to keel below with the upper side concave to it and 

 flaring and so the blade seems grooved along the middle, very obtu.se, 

 rounded, shorter than the keel and narrower, about 1.5 mm. wide. 

 Keel straight, with, tip very sharply rounded to erect and then ]w<>- 

 duced into a straight and sharp or rounded tip, 3 mm. high, dark- 

 yellow. Calyx a little obcorapressed at tip with broad simuses whitish 

 tube, about 2 mm. long, with the triangular teeth about half as long.
