Ecology & Habitat

Description

Tapertip Onion is a perennial herb, 1-3 dm high, arising from solitary or clustered, nearly globose bulbs with brown, honeycombed coats. 2-several long leaves, u-shaped in cross-section and 1-3 mm wide, arise from near the base of the stem. Several pink to rose-colored flowers are borne on stalks, 10-30 mm long, in a hemispherical inflorescence subtended by 2 papery, lance-shaped bracts. Each flower has 3 spreading, petal-like, outer tepals, which are 8-17 mm long, 3 shorter, sharp-pointed inner tepals, and 6 stamens, which are shorter than the tepals.

Diagnostic Characteristics

ALLIUM ACUMINATUM can be distinguished from other species by the combination of having rose-colored outer tepals which are longer than the inner tepals, and by often having more than 2 concave leaves. The more common A. BREVISTYLUM also has rose-colored tepals, but its leaves are usually more than 4 mm wide.
