Panarctic Flora


361201b Ranunculus glacialis subsp. alaskensis Jurtz.


Western Alaska: Rare
Southern Arcti Tundra: Presence uncertain
Shrub Tundra: Rare


Geography: American Beringian: ALA.

Notes: Murray and Elven: There is a Seward Peninsula plant morphologically different in several characters from the sympatric Ranunculus camissonis (see below). It is more similar to the amphi-Atlantic R. glacialis s. str. but differs also from that one in some features, especially the amount and length of hairs on the upper scape and calyx, in which it resembles R. camissonis, and the sepals of the Beringian plants are suborbicular and their apex rounded-obtuse vs. ovate and with apex subobtuse in the Atlantic plants. See Murray et al. (in print), also forwarding some hypotheses on the background of the Atlantic - Beringian disjunction. The name [Beckwithia glacialis] subsp. alaskensis has been applied in print (Lipkin and Murray 1997) as a nomen nudum.
