Canadian range

In Canada, A. umbellata was known prior to 1927, from Bamfield (Pachena Bay) and Tofino (Ahousat), on the central-west coast of Vancouver Island. Recently it was recollected in 2000 and observed again in 2001 at Clo-oose Bay, south of Tofino, (Figure 3; Douglas 2001; Douglas et al. 2002a, b). The plant did not reappear in 2002. A historic extent of occurrence including all three sites known would be <100 km². No data are available for its area of occupancy at the recent site at Clo-oose Bay but this is likely  <<20 km².
