25. A. modocense Jepson n. sp. Scape flattened, 11/2 to 2 (or 4) inches 

 high, prominently nerved, the 1 or 2 leaves twice as high ; reticulation of the 

 bulb-coat none or faintly and transversely quadratish ; umbel 20 to 30-flowered, 

 the pedicels 6 to 8 lines long ; bracts 2 ; perianth segments white with broad pink 

 midveins, oblong-lanceolate, 5 to 7 lines long; filaments % as long as the seg- 

 ments, adnate by the lower VA. and united by the dilated bases into a low but 

 distinct cup ; ovary cells with 2 low thin ridges confluent above and thus forming 

 a single curved obtuse crest. (Scapus planus, unc. li/2-2 vel 4 altus, folia 1-2,

A. NEVADENSE Wats. Bot. King, 351, pL 38, figs. 1-3 (1871), type loc. Trinity Mts. to 

 the East Humboldt Mts., Nev., is (ex. char.) very similar to A. modocense but the scapes are 

 terete and the reticulation of the bulb-coats rather minute and very much distorted. We have 

 seen no specimens from California, although it may be expected along the eastern boundary 

 north of Nevada Co.

 flowers ; flowers rose-colored, the lanceolate segments acute and erect or attenuate

 long ; stamens i/> to % the length of the segments ; ovary 3-lobed, the lobes creased 

 down the middle and produced above into narrow slightly toothed crests.
