Piperi, Robl, and L. Hellerae, Heller. With the last it agrees in being nearly erect; petioles often 13-15 cm long; leaflets often 9-10, 2-5 cm long; racemes 7-20 cm; flowers somewhat in whorls. With L. Piperi it agrees in pubescence loosely appressed; leaflets oblanceolate; pedicels with loose pubescence; standard glabrous. /5378. Lupinus Piperi, Robinson. 5106. " sericeus, Pursh. 5379.

" Robinsoni, Henderson, sp. nov. Bulb ovoid, large for size of plant, devoid of special reticulation; stem slender, 2/3 underground, slightly 2-edged; 5-7 cm long; leaves much exceeding the stem, arcuate, 1/8-2 mm wide; bracts 2, ovate, abruptly acute, rose-purple; flowers few to many, 7-9 mm long, on pedicels slightly shorter; perianth segments white to pinkish, with red midvein, obtuse, oblong; stamens 1/2 to 2/3 length of segments; ovary distinctly crested;style shorter than stamens, about equalling filaments, these rather coarse. Gravel and sand, confluence of Johns Day and Columbia Rivers, Sherman Co., Oregon. Differs from A. Brandegei, in- crested ovary, large bulbs, and very obtuse perianth segments. From A. parvum, Kell. it differs in its 2-edged stem, narrower leaves, and conspicuously crested capsule. I take pleasure in dedicating this species to Dr. B.L. Robinson of the Gray Herbarium at Cambridge. 5111. Allium Robinsoni, Henderson, ?
