 A amphctens, Torr, Fac. B. E. Suro. 4. 148, is a very young undeveloped state, and the name is inapplica- 

 ble to the more matured plant. It is also the A. falcifoUum and A. acuminatum of Whipple's Report, 

 mostly. Plate XXXVII. Fig. 4. Eeticulation ; enlarged thirty diameters. Fig. 5. Flower ; enlarged 

 two diameters. 



12. A. BISCEPTEUM, S. Watson. Bulb frequently bulbiferous, coats membranous and minutely sinu- 

 ous-reticulate ; scapes usually 2 or more, rather slender, 6-12' high ; leaves linear, 2-6" wide, flat, usually 

 equaling or exceeding the scape ; umbels many-flowered, occasionally bulbiferous ; pedicels 6-10" long, 

 spreading; sepals white or pinkish, 3-4" long, acute or acuminate, usually spreading; crests conspicu- 

 ous.— See page 351, and Plate XXXVII. 



13. A. Palmbri, S. Watson. Eeticulation irregular, subquadrate, the cell-outline minutely very 

 sinuous; scape 8' high, rather stout; leaves narrow-linear; umbel rather many-flowered, the spread- 

 ing pedicels 6" long ; sepals more or less deep rose-color, 3-4" long, acnte, erect-spreading, exceeding the 

 stamens.-New Mexico, (Palmer, 1869.) Probably also from Ft. Deflancc, (Newberry,) and Hell Canon, 

 (Hervey,) but the specimens are imperfect. Plate XXXVII. Fig. 10. Flower; enlarged two diameters.

 reticulation, the coU-ontline somewhat curved ; scape 6' high, stout ; leaves linear, thick ; umbel 25-flow-

(6.) Capsule not crested. Leaves very narrowly linear, except in A. BouglasU. 



17. A. Cajstadense, Kalm. Bulbs subfibrous-reticulate ; scape 1-2° high, usually tall and slender ; 

 umbel often densely bulb-bearing, with small pinkish flowers, the stamens and style included.— N. Eng- 

 land to Florida, and westward to Wisconsin, Missouri, the Indian Territory and Texas. 



18. A. MUTABILE, Mx. Bulb-coats fibrous ; scape 6-18' high, terete and usually slender ; leaves elon- 

 gated ; umbel usually many-flowered with slender spreading pedicels ; sepals 3" long, acute or acuminate 

 subspreading, longer than the stamens and style. — Florida to NT Carolina and west to Louisiana, and be-

Var. u.. Tall ; the usual form eastward, where it is less fibrous, but also frequent from Louisiana to

20. A. acuminatum. Hook. Eeticulation irregularly hexagonal, often conspicuous ; scape slender, 

 6-15' high ; leaves elongated ; pedicels 12-30, rather short, (4-9",) spreading; sepals 4-7" long, bright
