playanus but has a filiform stipe nearly as long as calyx. May 1902,

54. Astragalus pictus Gray PI. Fend. 37. (1849) as Phaca and Proc. 

 Am. Acad. 6 214 (1864) as var. foliolosus. A. pictus var, angustus Jones 

 and angustus var. pictus and A. angustus Jones, A. foliolosus Shel- 

 don, A. ceramicus var. Jonesii Sheldon, A. pictus Steud. was a no- 

 men nudum and A. pictus Boissier & Gall. (1859) was a synonym of A. 

 conduplicatus Bertol. (1864). The omission of Sheldon to see that 

 A. pictus was never published though this fact was specifically stated 

 by Gray (Proc. Am. Acad. 6 215) has led to several unnecessary syn- 

 onyms. The type of this species is rare and so the general character 

 of the species is given under the var. magnus which see. Pods oblong- 

 oval, about 1.5 cm. long. Leaflets 3-7 pairs, linear and about 1.5 cm. 

 long. Santa Fe New Mexico and extending over into the Navajo Basin 

 to Moctezuma canon on the borders of Utah and to Moab. 



Astragalus pictus var, magnus n. n. A. pictus Gray Proc. Am. 

 Acad. 6 215 as to the description, not citation. My specimens no. 5160 

 from Silver Reef Utah constitute the type. Pods oval, inclined to be 

 shortly-conical-acute at both ends, 2-3 cm long and 1-2 cm. wide and 

 high, mostly sbalicnv suicatf' along the ventral suture, papery and 

 iucliucd to be tvr<nsiiTC('nt. abruptly contracted at base into the stipe 

 which is nearly as long as calyx tube, the tip inclined to be a little 

 oblique and upturned but not always, pendent, few to single, seed- 

 bearing along the middle. Flowers very light-dirty-purple and water 

 lined coarsely, about 1 cm. long, stubby. Banner round, about 5 mm. 

 long, bent square off just beyond calyx tips to erect or a little more; 

 groove very wide, a half circle, 2 mm. wide below, 3 mm. above; 

 blade with branched purple veins and no white spot; sides reflexed 

 but very little, not extending beyond the keel because of being so 

 much arched. Wings barely longer than keel, very obliquely ovate 

 with tip bent at right angles and acutish on the lower side or a little 

 notched, about 3 mm. wid'e. wholly cnncealing keel. Keel with straight 

 base then arched to a half circle and tip acuminate and erect, about 

 ?■ mm. high, ?nd dull p'^riile. Petals with white cl-^ws. Pedicels slen- 

 der, 2-3 mm. long, and variable. Calyx tube turbinate-camnanulate, 

 about 2 mm. long, obcompressed above, rounded at base and equally 

 inserted, sinuses broad and teeth subulate and a little shorter than 

 tube, equal, not deeper cleft above. Peduncles fliform, spreading as are 

 the leaves, 2-5 cm. long, flexuous, axillary, the rachis as long or 

 longer and loc^p'y few-flowered. Stems flexuous, very slender, rarely 

 a foot high with few internodes 1-3 cm. long, single at the ends of 

 long and filiform rootstocks. Stipules green, triangular, erect, con- 

 nate, rarely .'i mm. loner, those of the rootstocks sheathing and with- 

 out tips and often 1 cm. long. Lowest leaves very small and with 

 about 3 pairs of oval to elliptical, contiguous leaflets 5 mm. long, 

 or absent, the nnper leaves with linear leaflets ?-5 cr-^ . long and rarelv 

 2 mm. wide, the unnermost leaflet a mere nrnlongaticn of the rachis 

 and a trifle widened and longer than rest. Leaves, peduncles and stems 

 about alike, all green, phyllodia-like. Frequent on sandy plains from 

 western Nebraska through Wynnv"""' to central Utah, Johnson's Pass 

 Aoui Mts. (West of Ff"'^'^^ and MiKord and southward to the Colo- 

 rado river and eastward through central New Mexico to the plains 

 of Kansas. Lower and part cf the Middle Temperate life zone. Bloom-
