microcarpus, Simms. 
" Piperi, Robinson? Seems just between L. Piperi, Rob:, 
and L. Hellerae, Heller. With the last it agrees in 
being nearly epect; 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.

Robinsonii, 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, l§-2 mm wide; 
bracts 2, ovate, abruptly acute, rose-phrple; flowers 
few to many, 7-9 mm long, on pedicels slightly shorter; 
perianth segments white to pinkish, with red midvein, 
obtuse, oblong; stamens £ to 2/3 length of segments; 
ovary distinctly crested; style shorter than stamens, 
about equalling filaments, these rather coarse. Gravel 
and sand, confluence of John 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.
