Galium labradoricum (Wiegand) Wiegand
Coefficient of Conservatism: 8
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt P-Forb

A northern (but not Arctic) species ranging westward in North America to Minnesota, Alberta, and the Northwest Territories. With us, it is especially characteristic of fens, but also openings in cedar and tamarack swamps, sedge meadows, and marshy ground along streams and lakes.

Sometimes difficult to recognize, especially if quite young. The leaves are not always reflexed (nor always revolute). Shade forms (e.g., in coniferous swamps) apparently can have broader, flatter leaves than plants in fens. Stem internodes may be scabrous, while in G. obtusum they are smooth. Besides the habitat and morphological characters in the key, it may be helpful to note that in G. labradoricum the terminal inflorescence is often overtopped by lateral branches later in the season. The stems, though weak, are often quite erect (as they may also be in G. obtusum).
