278 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



well developed into 2 pairs of horn-like processes: inflorescence 

 at first corymbose, when mature somewhat elongated but remain- 

 ing dense ; pedicels 5-8 mm. long, slender and terete but usually 

 somewhat wing-margined at the very base, horizontal or slightly 

 ascending: pods irregularly torulose, arcuate, ascending, 2-3 cm. 

 long, stipe 1-2 mm. long; styles less than 1 mm. long, stigmas 

 small, entire: seeds frequently apiculate. 



Distribution: Washington and Oregon. Type: Nuttall from 

 "elevated plains of the Rocky Mountains towards the Oregon, 

 as far as Wallawallah." 



Specimens examined : 



Washington: Satus, Yakima County, July, 1898, Elmer 1073 

 (Mo. Bot. Gard. Herb.) ; Squaw Creek, Yakima County, Aug. 26, 



, Cotton 874 (Mo. Bot. Gard. Herb.) ; near Ellensburg, Sept., 

 1883, Brandegee 686 (Univ. Calif. Herb.). 



Oregon: valley of the Ochoco, July 23, 1901, Cusick 2691+ 

 (Univ. Calif. Herb., Rky. Mt. Herb., and Mo. Bot. Gard. Herb.) ; 

 near Prineville, Crook County, Aug. 26, 1894, Leiberg 817 (Univ. 

 Calif. Herb, and Mo. Bot. Gard. Herb.). 



The identity of Nuttall's type of this species seems definitely 



established. The original description coincides more closely with 

 the northwestern plant than with the nearly related species. Mr. 

 J. F. Macbride who kindly examined a specimen at the Gray Her- 

 barium that is evidently a co-type, writes me that the plant of 

 Nuttall has pedicel bases that are definitely broadened and the 



about 6 mm. lone. This broadenin 



t> 



the pedicel bases is characteristic of Washington material. The 

 habitat as originally given would seem to indicate that the type 

 locality was in the far northwest.

Biennial, glabrous throughout, glaucescent: stem stout, panic- 

 ulately branching above: radical leaves 10-25 cm. long, thick, 

 oblanceolate, obtuse, irregularly margined or entire, blade nar- 

 rowed to a broadly winged petiole: petals white (?), narrowly 

 spatulate, 7-10 mm. long, much exceeding the sepals; stamens 

 slightly exserted, anthers about 2 mm. long; nectar glands 2 

 (each pair coherent), well developed: inflorescence dense, scarcely 

 corymbose; pedicels stout, nearly horizontal, 8-10 mm. long,
