Astragalus Seatoni var. Crucis n. var. Pods narrowly oblonc:, 

 and shortly acuminate, 8-12 mm. long. Flowers about 4-5 mm. 

 long. Upper stipules large, ovate and green. Leaflets narrowly 

 oblong, 1 cm. long and 3 mm. Avide. Pringle's No. 6445 Sierra de 

 Las Cruces at 10,000 ft. alt., state of Mexico, August 13, 1896. 



263. Astragalus Goldmani n. pp. Pods half-oval, about 5 mm. 

 long, 3-4 mm. wide and 2 mm. high, ashy, cordate at base and about 

 sessile, truncate and minutely deflexed-apiculate at tip, narrowly 

 sulcate to the middle dorsally and wholly 2-celled to tip, rather flat 

 or rounded ventrally and the suture thickened but not raised and 

 straight to a little concave, cross section reniform to triquetrous- 

 renifoi-m, not cross-ribbed, closely reflexed in linear spikes 1-2 dm. 

 long. Flowei's white or ochroleucous, soon reflexed, 5-7 mm. long, 

 stubby and wide. Banner nearly round, about 3 mm. long, abruptly 

 arched to erect at end of calyx tube and with sides reflexed 1 mm. 

 wide. Wings broadly oblong and blunt, arched 30°, as long as ban- 

 ner and 2 mm. longer than the half-circular keel which is fully as 

 high as long and rounded and purple-tipped. Calyx hemispherical, 

 cleft deeper above, equally inserted, nigrescent or silvery hairy on a 

 minute and reflexed stout pedicel, teeth triangular, rather shorter 

 than the tube. Bi'acts filiform, white, about 3 mm. long. Peduncles 

 1-2 dm. long, strict, in the upper axils, fruiting rachis often 3 dm. 

 long, rather loosely fruited. Leaves about sessile above, rarely 1 

 dm. long, with elliptical-oblanceolate leaflets 1-2 cm. long, which 

 are long-petiolulate, rather distant, thin, sparsely to densely white- 

 hairy with rather tangled hairs fixed by the base and sometimes 

 rather woolly, leaflets on the lower leaves small and obovate, mostly 

 rounded and obtuse but sometimes shortly acute. Stipules triangu- 

 lar-subulate, 4-6 mm. long, green. Stems slender, erect or decum- 

 bent only at base, 2-3 ft. high, simple, tufted from a slender and 

 rather woody root. Probably Lower Temperate life zone. The type 

 is No. 335619 National Herbarium, Goldman's No. 119 from Pa'rral 

 Chihuahua Mexico, Sept. 19, 1898. Lower Temperate life zone. 

 E. A. Goldman. Other specimens which I refer here are Palmer's 

 No. 440 (Nat. Heb. 304738) from Pasquiaro Durango, 1896. Near 

 Santa Gertrudis Tepic, Aug. 8, 1897, J. N. Rose, No. 302355, a 

 woolly form with nigrescent calyx as in the type. E. Palmer No. 

 278 (Nat. Herb. 571298) from Tepehuanes Durango, June, 1906. 

 This is a very robust form with stout stem and densely white-vil- 

 lous and white calyx. 



264. Astragalus Cleveland! Greene Torr. Bull. 9 121 (1882). 

 Pods about half-oval-ovate, with ventral suture inclined to be a 

 little concave and with declined, pungent and minute triangular tip, 

 broadly sulcate dorsally, smooth, very rigid, 5-6 mm. long, 2 mm. 

 wide, 1-2 mm. high, with cross section deltoid-cordate. Flowers 

 about 5 mm. long, in spikes which in fruit are often a foot long. 

 Banner round, about 2 mm. long, with sides reflexed Vs mm. wide, 

 arched abruptly at end of tube to 45°, a little shorter than wings. 

 Wings oblong and with a lanceolate tip, arched to 45% fully 1 

 mm. wide, fully twice as long as keel. Keel arched to a half circle 

 from base, obtuse, about 2 mm. high and long. Calyx broadly 

 campanulate, equally inserted below, rather oblique at tip and 

 with very broad upper sinus, with teeth unequal, subulate and as 

 long as tube or more, ashy. Pedicels and bracts minute, about 

 equal, the latter triangular, 2 mm. long. Peduncles filiform, 5-10 

 cm. long, strict, many. Upper leaves sessile, the lower smaller 

 and short-petioled, 5-7 cm. long. Leaflets 5-12 mm. long, narrowly 

 elliptical, obtuse, green, but minutely pubescent, long-petiolulate. 

 Stipules subulate, about 4 mm. long. Stems a foot or two high, 

 very slender, ascending to erect, with peduncles in all the upper 

 axils. Internodes slender but shorter than the leaves. Lake County, 

 California. Tropical.
