Allium tolmiei produces ovoid to oblique bulbs up to 0.79 inches (2 cm) long, the bulbs generally disappearing at flowering time but then reforming later. Flowers are bell-shaped, up to 0.47 inches (12 mm) across; tepals white to pink with reddish midribs; anthers purple or yellow; pollen yellow.[3][5][6][7][8]
Taxonomy
The botanist John Gilbert Baker scientifically described a new species in the Allium genus in 1876, which he named Allium tolmiei . Though it was described as a variety of Allium douglasii in 1947 by Hamilton Paul Traub, it is generally accepted as a species. Together with its genus it is classified in the Amaryllidaceae family and has two varieties according to Plants of the World Online.[9]
- Allium tolmiei var. tolmiei[10] - scapes 5–30 centimeters (2.0–11.8 in) tall; stamens shorter than tepals
- Allium tolmiei var. persimile Ownbey (syn Allium persimile (Ownbey) Traub & Ownbey)[11] - scapes 10–40 centimeters (3.9–15.7 in) tall; stamens longer than sepals—known only from the Seven Devils Mountains in Idaho[12][13][14]
