the crown of a slender -root, apparently Avinter annuals. Darwin 

 Mesa near Keeler California. Lower Temperate life zone. 



231. Astragalus Nevinii Watson Proc. Am. Acad: 21 412 

 (1886). Pods narrowly oblong and a little arcuate, the body about 

 1.5 cm. long and 4 mm. high and 2 mm. wide, smooth and closely 

 reticulated, chartaceous, barely to triangular-acute at both ends, 

 sharply sulcate to the middle, wholly 2-celled. Stipe about twice as 

 long as calyx. Flowei's rather wide, about 1 cm. long, light-colored, 

 rather capitate. Banner oblong, arched abruptly to 45^ at calyx 

 tips, C-8 mm. long. Wings narrowly oblong, 2 mm. longer than 

 keel, about 3 mm. shorter than banner, arched somewhat. Keel 

 straight, with tip erect, triangular and 2 mm. high. Calyx broadly 

 campanulate, about 3 mm. long, with the triangular teeth about half 

 as long as tube, soon reflexed. Bracts very small and as long as the 

 very stout pedicels. Peduncles about as long as the leaves,- in 

 fruit loosely spicate on the upper half or third. Leaves all petioled, 

 about 1 dm. long, recur\^ed. Leaflets 5-7 pairs. Plants a foot or 

 two long. San Clemente Island, Nevin and Lyon. 



232. Astragal-js Traskias Eastwood Proc. Cal. Acad. 3 102 fig. 

 (1897). A. Nevinii var. Traskiae^ Jones. Pods almost exactly 



those of A. Howellii but more arcuate, arcuately half-elliptical-ob- 

 long, or, obliquely narrowly oblong and rather abruptly narrowed 

 to a triangular flat beak 3 mm. long which is in line with the ventral 

 suture, the body fully 1.5 cm. long, 3 mm. high and 5 mm. wide, 

 very shortly-triangular at base, broadly and rather shallow-sulcate 

 dorsally, coriaceous, finely corrugated, short-woolly, completely 2- 

 celled, apparently ascending, in close clusters, stipe as long as calyx 

 and teeth. Flowers white, becoming yellowish, about 12 mm. long, 

 ascending in a close head. Banner oval,, about 8 mm. long, arched 

 abruptly to 45° at end of teeth, with sides reflexed 1 mm. wide be- 

 low, 2-3 mm. longer than wings. Wings broadly linear, about 1 mm. 

 wide and 1 mm. longer than keel, arched a little. Keel obliquely 

 oblong, about 4 mm. long and 2 mm. wide, the tip nearly erect and 

 rounded and a little darker. Calyx tube narrowly campanulate, 

 about 4-6 mm. long and 2.5 mm. high, rounded at base and equally 

 inserted on a very thick pedicel, cleft a little deeper above, not 

 oblique, the triangular teeth one-fourth to one-third as long as tube, 

 nigrescent. Pedicels and bracts minute. Peduncles nearly 1 dm. 

 long, floral rachis 2-3 cm. long. Leaves rarely 1 dm. long, narrow, 

 tapering, (Nevinii not noticeably so), with 8-10 pairs of leaflets 3-7 

 mm. long. Stems thick, forming broad mats 1-3 ft. long, with innu- 

 merable old leaf petioles forming a dense mass below. On cliffs in 

 high and dry places, San Nicholas Island. Blanche Trask. This can 

 probably be kept apart from A. Nevinii on the pod character and 

 larger flowers, but the plants are suspiciously alike. This group is 

 the representative of A. Howellii in the south. 



233. Astragalus Arthuri Jones Cont. 8 20 (1898). Atelo- 

 phragma Rydberg. Pods gladiatc, about like those of Brassica alba 

 but narrower, at tip the dorsal suture is nearly straight and the 

 ventral narrowed to it, at base the opposite is true, sulcate dorsally 

 with a narrow groove, chartaceous, nearly smooth, mature pods 

 laterally flattened with concave sides, fully 2-celled, cross section 

 triangular-cordate, ventral suture the more arched, thick at base and 

 prominent externally. Flowers reflexed, white, like those of A. 

 stenophyllus, about 1.2 cm. long. Banner about 1 cm. long, ovate, 

 arched at calyx tips to nearly a half circle in gentle curve, the nar- 

 row tip much reflexed, about 4 mm. longer than wings. Wings nar- 

 rowly oblong, about 2 mm. wide, arched to 30°, about 3 mm. 

 longer than keel. Keel arched nearly from base to tip in a half 

 circle, 4-5 mm. long and high, the tip triangular, acute a little 

 more than erect, not dark. Calyx tube nigrescent, thin, thickened 

 at lower corner where it is inserted on pedicel, short-cylindric, hya- 

 line, 4 mm. long, a little oblique below but not at mouth, teeth subu-
