 or teretish, 1 to 2y 2 lines thick, 4 to 8 l / 2 inches long above the sheath (much ex- 

 ceeding the scape) ; flowers many in a compact umbel, the pedicels 3 to 4 (or 5) 

 lines long ; bracts 2 ; perianth reddish or light pink, 6 to 7 lines long, the segments 

 straight, stamens about % the length of the perianth-segments; ovary crests

Locs. Reno, Nev., Cowgill. Owens Valley, Cal., ace. Jones (Contrib. 10:16), who says the 

 corms produce runners with brilliant shiny bulblets strung along them.

 Humboldt to the Havallah Mountains, Nev. 



9. A. anserinum Jepson n. sp. Scape terete, 5 to 6 inches high ; leaf one, 

 flat ; umbel about 20-flowered ; pedicels about 4 lines long ; perianth purplish or 

 pinkish, its segments oblong-ovate, 5 to 6 lines long, spreading at tip ; stamens 

 about % as long as the perianth ; ovary-cells with 2 crests ; crests oblongish, much 

 lacerate or laciniate, twice as long as the ovary; stigma slightly 3-cleft. 

 ( Scapus teres, unc. 5-6 altus ; folium singulare planum ; ovarium 2-cristatis lobis ;

10. A. campanulatum Wats. Scape 4 to 7 or 11 inches high, erect, often 

 flexuous ; leaves 2 ; umbel 10 to 50-flowered ; pedicels 4 to 15 lines long ; flowers 

 somewhat campanulate, pink or rose-color ; perianth-segments broadly ovate, acute 

 or short-acuminate, 3 to 4 lines long, nearly equal, y longer than the very slender 

 stamens and style ; filament bases nearly equal ; ovary prominently crested, the 

 crests somewhat horizontal. 



Usually in dry places, Sierra Nevada, south to Tehachapi, north to Shasta 

 Co., thence southerly to eastern Humboldt Co., 3000 to 6000 feet. Passing into 

 var. bidwelliae at the higher altitudes. The accumulation of material has also 

 tended to weaken the distinctions betwen A. campanulatum and A. bisceptrum 

 but we continue to retain the two as species.
