5. Astragalus Antiselli Gray Bot. Cal. 1 152 (1876). A. Hasseanus 

 Sheldon. Pods in the type about 2 cm. long and 5-7 mm. high, not 

 much flattened laterally and with about oval crass-section finely ret,i- 

 culated all over, oblanceolate to narrowly elliptical, tapering from near 

 tip into the dark filiorm stipe which is about 3 times as long as calyx, 

 tip barely acute and apiculate, sutures about equally arched. Flowers 

 about 1 cm. long. Calyx tube as in A. stenophyllus bu't teeth 

 triangular and about half as long as the tube. Pedicels twice as long 

 as the short bracts. Peduncles 1-2 dm. long, about as long as leaves, 

 the rachis a half to a third more and rather densely flowered. Leaves 

 7-15 cm. long. Leaflets 10-16 pairs, linear-oblong, to elliptical-oblong, 

 rounded, 1-2 cm. long, 4-7 mm. wide, white-ribbed, ashy with minute 

 white hairs closely appressed and fixed by base. Stems slender but 

 rather rigid and from a woody shrubby base, ashy, somewhat sulcate, , 

 erect. A. Hasseanus Sheldon is a form with longer and more acuminate 

 pods. This may hybridize with A. trichopodus. On dry slopes, in 

 the hills of the Coast range from San Luis Obispo California and south- 

 ward, Antelope Valley, Davidson. Tropical. 



Astragalus Antiselli var. phoxus Jones Cont. 10 65 (1902). A. 

 gaviotus Elmer. Pods with body about 2 cm. long, 7 mm. high and 1 

 mm. thick, almost completely flattened laterally, on a stipe fully half 

 as long, oblanceolate to linear-elliptical, sutures either equally arched 

 or the ventral the more so, shortly acuminate at both ends, opening 

 first at tip, apiculate. Flowers 15-20, about 1.5 cm. long. Banner 

 arched to erect, 4 mm. longer than wings, with sides reflexed 2 mm. 

 wide in the middle only. Wings linear-oblanceolate, nearly 2 mm. 

 longer than keel and much narrower, little arched. Keel exceeding 

 the calyx tube by 4 mm. nearly straight, tip sharply incurved to a 

 at least 110 degrees, about 3 mm. high, blunt, not dark. Pedancies 

 (and stems) sulcate, 1-3 dm. long, stout. Leaflets 12-15 pairs, nearly 

 contiguous, oblong-elliptical, about 1.5 cm. long, somewhat reduced 

 above. Stipules small and not connate. The plants have the habit 

 of A. leucopsis. Santa Inez river southern California and vicinity. 

 Lower Temperate life zone. 



This group connects directly with the Inflati through A. oxyphysus 

 and trichopodus. 



6. Astragalus porrectus Watson Bot. King 75 (1871). Pods 

 about 1.5 cm. long, exclusive of the stipe, about 4 mm. high and 2 mm. 

 wide, much laternally flfttened, shortly acuminate at both ends, at 

 tip into a subulate and straight beak 1-2 mm. long, at base into a very 

 stout tapering straight stipe often twice as long as calyx, arcuate near 

 the base, erect at tip or a little incurved and calyx nearly hori- 

 zontal. Flowers about 1 cm. long, white, ascending, yellowish when 

 dry. Banner oblong-oval, abruptly erect at calyx tips, with sides reflex- 

 ed about 2 mm. wide at base, less so above, rather fleshy, the ereot 

 part about 1 mm. long. Wings broadly oblanceolate or obliquely el- 

 liptical, acutish, about 1 mm. longer than keel and 2 mm. shorter 

 than banner, nearly 2 mm. wide, ascending. Keel about 3 mm. long, 

 the base straight and tip nearly erect and triangular. Calyx hyaline 

 the tube about 3 mm. long and 2 mm. high, abruptly rounded at base 

 and inserted a little below the middle, the tria.ngular teeth about half 

 as long. Pedicels rather stout, about 2 mm. long and equaled by the 

 triangular bracts. Peduncles stout, in the upper axils, about 1 dm. 

 long, the rachis often twice as long or more. Leaves 5-7 cm. long, 

 short-petioled. Leaflets 4-6 pairs, thick, about 1-1.5 cm. long, nearly 

 contiguous, mostly with a broad notch at tip. Stems flexuous, slen- 

 der, nearly erect, about 2 ft. high, from a strong erect root. Trinity 

 Mts. Nevada and westward nearly to Reno on rocky slopes. Lov/er 

 Temperate life zone, rarely collected. Watson, Miss Stokes. The 



plant called porrectus by Coville from Pahrump Valley is A. Preussil. 



This plant has the habit of A. Orcuttianus but the pod is vetch-like.
