CommentsSome authorities consider Narrow-Leaved Wild Leek to be a variety of the more common Wild Leek, or Allium tricoccum burdickii (see eFloras, FNA Vol. 26, pp. 224-226), while other authorities consider this species to be distinct, Allium burdickii (Mohlenbrock, 2002). The latter viewpoint has been adopted here. Narrow-Leaved Wild Leek can be distinguished from Wild Leek by its more narrow leaves (less than 1½" across), greenish petioles (rather than reddish), fewer-flowered umbels (less than 21 flowers). The bulbs of Narrow-Leaved Wild Leek are also supposed to be smaller in size, and the stamens of its flowers may be less exerted than those of Wild Leek. Because the range of these two species (or varieties) overlap, it is possible that they hybridize. As a result, some collected or photographed specimens may be difficult to classify. Both of these species (or varieties) are distinct from other Allium spp. in Illinois by their wider leaves and the absence of these leaves when the flowers bloom.
