A. VINEaLE, L. (FIELD GARLIC.) Scape slender, clothed with the sheathing bases of the leaves below the middle (1--3 high); _leaves terete and hollow_, slender, channelled above; _umbel often densely bulbiferous; filaments much dilated, the alternate ones cuspidate_ on each side of the anther.--Moist meadows and fields; a vile weed eastward. June. (Nat.

from Eu.)

3. NOTHoSCORDUM, Kunth.

Flowers greenish or yellowish white. Capsule oblong-obovate, somewhat lobed, obtuse, with the style obscurely jointed on the summit; cells several-ovuled and -seeded. Filaments filiform, distinct, adnate at base. Bulb tunicated, not alliaceous. Otherwise as in Allium. (Name from ?????, _false_, and s???d???, _garlic_.)

1. N. striatum, Kunth. Scape 1 high or less; bulb small, often bulbiferous at base; leaves narrowly linear; flowers few, on slender pedicels, the segments narrowly oblong, 4--6” long; ovules 4--7 in each cell. (Allium striatum, _Jacq._)--Prairies and open woods, Va. to Ind., Neb., and southward.

4. ANDROSTePHIUM, Torr.

Perianth funnel-form, the cylindrical tube equalling the somewhat spreading limb or shorter; segments 1-nerved. Stamens 6, in one row upon the throat; the filaments united to form an erect tubular crown, with bifid lobes alternate with the oblong versatile anthers. Capsule sessile, subglobose-triquetrous, beaked by the stout persistent style; seeds large, few to several in each cell.--Scape and linear leaves from a membranous- or fibrous-coated corm; pale lilac flowers umbellate; pedicels not jointed; involucral bracts several. (Name from ????, for _stamen_, and st?f??, _crown_, referring to the stamineal crown.)

1. A. violaceum, Torr. Scape 2--6' high; flowers 8--12” long or more, usually exceeding the stout pedicels, the tube nearly as long as the limb; crown scarcely shorter than the limb.--Kan. to Tex.

5. CAMa.s.sIA, Lindl.

Capsule oblong or obovate, 3-angled, loculicidal, 3-valved, with several black roundish seeds in each cell.--Scape and linear leaves from a coated bulb; the flowers in a simple raceme, mostly bracted, on jointed pedicels.
