in flower and with all the leaflets short, oval and very obtuse, and 

 peduncles only half as long as the leaves probably belongs here. A. 

 Bodini is the ordinarily well developed form. 



28. Astragalus Yukon is n. sp. Pods immature, oblong-lanceolate, 

 acuminate and somewhat arcuate upward, hardly 5 mm. long, ascend- 

 ing. Eastwood pods are about 7 mm. long by 3 mm. wide, broadly 

 oblong, round to a little oblate in cross-section, 2-3 seeded, thin, 

 short-hairy, erect, a trifle cordate at base, with strong raised ven- 

 tral suture externally, shortly and very obliquely acute. Flowers 

 purple, about 8 mm. long, about 5 at the ends of almost capillary ped- 

 uncles longer than the leaves. Banner obovate, about 5 mm. long, 

 arched abruptly at end of calyx to nearly erect, with sides reflexed 

 about 1 mm. wide to tip; white spot triangular and purple veined, 

 with the center produced as a white strip to tip of blade, 2-3 mm. 

 longer than wings. Wings oblanceolate, oblique, a little arched, 

 rounded, about 1 mm. longer than keel. Keel about straight along 

 the base, about 4 mm. long, the tip abruptly erect, obtuse and 3 

 mm. high. Calyx tube about 2 mm. long, slightly oblique at both ends, 

 nearly equally inserted, the triangular teeth about as long. Pedun- 

 cles about 1 mm. long and equaled by the bracts. Pedicels 5-7 

 cm. long, in the upper axils. Leaves 2-5 cm. long, all rather long- 

 petioled, innumerable, narrow. Leaflets 3-5 pairs, oval to elliptical, 

 rarely 5 mm. long, rounded, ashy with rather coarse stiff white hairs, 

 sparse, appressed. Internodes very many, rarely 1 cm, long. Stems 

 petioles and peduncles almost capillary, stems very many from a 

 stout and erect rrot, ni'ich branched and forming delicate mats often 

 a foot or two wide. Stipules small, rarely 3 mm. long. Though the 

 pcds are immature the plant is clearly new. No. 1082 Gorman from 

 Ranch valley near Fort Selkirk on the Yukon in mnist meadows. July 

 5 1899. The Ayan name is Kto-goonh. Distributed as A. debilis.

29. Astragalus Bourgovii Gray Proc. Am. Acad. 6 227 (1864) Pods 

 fully 15 cm long exclusive of the 2 mm. long stipe, from flatfish to 

 rrnrly round in cr-^ss-sect'on, 4-5 m^^. high, half-ovate-lanceolate to 

 obliquely oblong-oblanceolate, acute at both ends. Flowers ascend- 

 ing, few, racemose, stout and thick, about 1-1.5 mm. long, purple. 

 Pinner 7 mm. long, ovate-oval, short and abruptly arched at the ends 

 of the calyx teeth to 90 degrees, but little longpv than the keel, with 

 sides much reflexed. Wings little shorter than the banner, lanceolate, 

 a little arched 1 mm. wide, narrower than keel. Keel 7 mm. Ions;, 

 straight, sharply rounded, 2 mm. shorter than the banner, purple aabove, 

 with ti)ie erect, acute and 3 mm. high, a trifle shorter thin the win?'^. 

 Calyx tube oblong-campanulate, 3-4 mm. long, narrowed below, with 

 mouth scarcely oblique, with teeth triangular to filiform-subulate and 

 about half as long as tube. Pedicels slender, mostly twisted and with 

 pod inverted, about as long as the calyx teeth and about 2 mm. long in 

 flower, but the lower fruiting pedicels often 1 cm. long. Bracts- ovate 

 to subulate, delicate, 1 mm. long. Peduncles almost filiform, nearly 

 all terminal, much longer than the leaves, about as long as the 

 stems, 10-15 cm. long including the short rachis. Racemes short, spi- 

 cate in flower, with about 5-10 flowers. Leaves not over 7 cm. long, 

 slender, with lower petioles about as long as the leaf rachis. Leaflets 

 acute at both ends, narrowly ellinticnl to oblone or lanceolate, not over 

 1-1.2 cm. long, 4 mm. wide, of 7-8 pairs, puberulent, nearly contiguous, 

 reduced only at the ends of the leaves. Stipu'es scarious, 4 mm. long 

 nearly wholly connate. Stems 1-2.5 dm. high, ascending, with inter- 

 nodes not over 2-3 cm. long. Root woody, crowned by many filiform 

 and subterranean stems which form loose mats. Pubescence strigulose, 

 sparse and short. This has the habit of A. aboriginum and resembles 

 A. debilis but the leaves are more rakish and the leaflets sharp. Saw-
