DescriptionAconitum noveboracense (northern monkshood) is a federally listed, threatened plant species endemic to the states of Iowa, Ohio, New York, and Wisconsin. The presence of bulbils in some populations of this species has been noted, but previously not investigated in detail. The anatomy of vegetative propagules produced in the leaf axils and bracts of A. noveboracense is presented. Microscopy observations confirm that the axillary propagules are bulbils. Minute, fleshy, and imbricate leaves join at the base of a compressed stem and adventitious roots can develop while still attached to the parent. Vegetative propagation via bulbils occurs sporadically in A. noveboracense, and may have positive implications for its persistence by supplementing seed production and the formation of perennating daughter tubers.
Keywords: Aconitum noveboracense, asexual reproduction, endangered species, North America, propagules, vegetative propagation.
