A pretty genus of white-flowered herbs with fleshy fasciculated roots, natives of Europe. The name is said to be derived from a flower, and a hedge, but the application is obscure. The limits of this genus have been variously defined by different authors. It belongs to the capsular group, and the perianth-segments either spread from near the base, or they are campanulately united, and the short stamens have naked or bearded filaments. Seeds numerous.
1. A. Liliago, syn. Phalangiurn Liliago. St. Bernard's Lily. - Leaves tufted, narrow, channelled, 12 to 18 inches high. Scape usually simple; flowers pure white, small; perianth-segments spreading; style curved. May and June.
2. A. Liliastrum (Czackia). St. Bruno's Lily. - The sweet-scented flowers are larger in this species, and campanulate, and the leaves not channelled. A very beautiful plant with a simple flower-scape about the same height as the last. July and August.
3. A. ramosum. - This species has long narrow channelled leaves shorter than the scape, like No. 1, but the inflorescence is branched and attains a height of 2 feet or more. Perianth-segments narrow and spreading, style straight. June and July.
