riff Id calyx lobes hyaline- margined and widely spreading, 1 ram. 

 longr. Ovarv densely hairy like the leaves. Petals white. Anthers 

 purple. Fruit oval, about 5B.S mm. 1 nig, scarcely ribbed on the 

 back and without evident lateral rib,s or wings, rounded, much 

 compressed dorsally and cross section oblong, much like Fig. 83 

 in Coulter and Hose V. first monograph, but much flatter and the 

 edges of the seed nearly touching, and wingless, rounded at both 

 ends, onlv one seed matured (this probably distorts the normal 

 shape). Oil tubes obscure apparently single in the intervals. Col- 

 lected by Mrs Joseph Clemens on Mt. Whitney Cab, alpine, also 

 on Kear.-arge Pass July 28 1910, The habit is that of the acaules- 

 cent species of Cvmopterus. 



Astragalus Purpusi n. sp. 

 Didymocarpus-Biazoensis group. A caespitose perennial, pros- 

 tiate, much branched throughout, with habit of A. lentiformis 

 and H< ntrophyta. Lower internodes very short and rather woody, 

 upper slender and 1.5-4 cm. long, about as long as the leaves, ap- 

 preneed-hairy, round Stipules adnate, connate, hyaline, conspic- 

 uous, about :* mm. long and wide, quadrangular, truncate, hairy 

 above, the uppermost connate only above and deltoid, appressed. 



Leases delicate, with filiform rachis, 1.5-4 cm. long, spreading, 

 the small low. r ones short petioled, the rest sessile, with about 10 

 pairs of emarginate and oval-obovate to oblanceolate thick leaflets 

 w< ich are petiolulate and jointed to the rachis, nearly contiguous, 

 smooth above ami folded, sparsely appressed-pubescent below, the 

 broader ones about 2 mm. long, and the longer ones 4 mm. long 

 and 1.5 2 mm. wide. Peduncles filiform, in the upper axils only, 

 and ascending, as long as the leaves, with capitate and broadly 

 ovate inflorescence only slightly elongating in fruit and compactly 

 flowered with 10 1 % light-purplish flowers 3 mm. long. Bracts mi- 

 nute, not 1 mm. long, ovate, hyaline, a little longer than the 

 flowering and about as long as the ^fruiting pedicels, persistent. 

 Calyx obconic, equally inserted, appressed-black-hairy, tube about 

 1 mm. long; teeth triangular, nearly equal, f erect f half as long as 

 tube. Banner obovate, about > mm. long, abruptly arched to 90 



at calyx tips, purple and dark-striped, slightly longer than the 

 broadly-linear nearly straight and blunt and white or purple wings. 

 Ketd very broad, straight, the tip rounded to a little more than \ 

 eircle and with the minute tip erect. Pods on a stipe nearly as 

 long as the calyx, pendent on a reflexed pedicel, obliquely ovate, 

 shortl v acute at both ends^cnnspieuously 'flattened laterally, with 

 triquetrous cross section, ventral suture slightly arched and railed, 

 the dorsal impresssd \ the width of the pod and then continued
