Black Hawthorn (Crataegus douglasii): A single 1939 collection identified as suspecies suksdorfii is the only one in ARCTOS. A collection from Juneau area originally labeled as this species was later identified as Pacific Crabapple (Malus fusca).
FNA treats C. d. suksdorfii as C. gaylussacia and in the range information does not list Southeast Alaska, but does say it occurs in the vicinity of Anchorage.
FNA range information for C. douglasii indicates it occurs in 'panhandle of Alaska'
Given the lack of collections and apparently conflicting information, it's not clear which species should be expected in the region, nor the extent to which they occur.
