Meadow Woollyheads

Description: English: Psilocarphus elatior, meadow woollyheads, example plant of a population found along gravel road in southeast Alaska. This plant is very abundant in drying areas along this gravel road system. The species is probably not indigenous here, but brought in by logging in the 1970s. Although non-native, it does not seem to be spreading into local forest or muskeg, but confined to the disturbed habitat of the roadbed and road margin.

Description: English: Psilocarphus achenes and calyxes, microscope view, approximately 40×. Species of Psilocarphus are distinguished by details of the achenes and their enclosing inflated calyxes. This microscope view, approximately 40×, shows the shape of the achenes and their slightly offset tips, and the lobe on the side of a calyx. P. elatior is the best-fit ID (Illustrated Flora of British Columbia, Douglas et.al. 1998), though the plants in this population do not exactly match the description.
