edit

Allium denticulatum grows from a reddish-brown spherical to oval-shaped bulb just over a centimeter long. It produces a stem up to 18 centimeters tall and a single cylindrical leaf up to twice as long as the stem. The inflorescence contains up to 30 flowers with deep pink to purplish tepals which are toothed at their tips (this being unusual in the genus).[2][3][4][5][6]

Taxonomy

Some sources prefer to treat this taxon as a variety of Allium fimbriatum, A. fimbriatum var. denticulatum, rather than a distinct species.[1] Allium denticulatum Kit is a synonym of a different species, Allium carinatum.[7]
