erect, usually simple.


mostly whorled at stem apex, some alternate on proximal stem;

blades of distal leaves elliptic to suborbiculate, (2.4–)4–11 cm × 15–55 mm (narrower in some plants along Vancouver Island and Washington coast), widest ± at midlength (proximal leaves abruptly much smaller, 0.1–0.5 cm × 0.7–1.3 mm, ± scalelike), apex rounded to acute.

n North America; Eurasia

In British Columbia, Trientalis latifolia is known from scattered populations along the coast and the American border. Specimens from a disjunct population in central Yukon (E. Hultén 1968; W. J. Cody 1996) were not examined.

Species 3 (3 in the flora).

The number of species recognized in treatments of Trientalis has varied from two to four; in some, only T. europaea and T. borealis have been recognized, sometimes T. latifolia has also been recognized, while other authors have segregated the northern Pacific populations of T. europaea as T. arctica. We consider only three to be solid species.

1. Flowering pedicels usually longer than leaves; proximal leaves gradually smaller than terminal cluster, at least some wider than 1 mm; distal leaves widest beyond midlength.
T. europaea
1. Flowering pedicels usually shorter than leaves; proximal leaves abruptly much smaller than terminal cluster, all 1.5 mm or narrower; distal leaves widest at or below midlength
