Introduction to Vascular Plants
SUBTAXA PRESENT IN BC
Species Information
General:
Plants perennial, loosely mat-forming, from a branched caudex.
Leaves:
Leaves in multiple dense basal rosettes, strap-shaped to oblong, margins ciliate, surfaces usually grey soft-hairy with simple hairs (rarely glabrescent), 3-15 mm.
Flowers:
Inflorescences of 2-8 flowers; involucral bracts lanceolate to ovate. Flowers short-stalked; corollas salverform, white to pink-tinged with a yellow throat (throat turning pinkish with age), 4-8 mm wide; calyces broadly campanulate to subglobose, sometimes slightly keeled, long-hairy, lobes ovate-lanceolate 2-5 (8) mm; pedicels erect, 0.5-1.5 mm long, shorter than the calyces. Flowering Jun-Aug.
Fruits:
Capsules globose or subglobose, about equalling the calyx, 5-valvate.
Stems:
Stems prostrate. Scapes solitary, sparsely to densely hairy with long, soft, shaggy hairs, 2-10 cm tall.

Taxonomic Notes
This distinctive, showy species is closely associated with calcareous environments and coarse, well-drained soils. Our plants represent the North American component of a circumpolar complex; the remaining taxa in this complex occur in Eurasia. North American and northern Eurasian populations of A. chamaejasme have traditionally been attributed to ssp. lehmanniana (Spreng.) Hult.; however, as ssp. lehmanniana should properly apply only to European populations (at least populations from the Caucasus), northern and North American plants are better recognized as ssp. andersonii (Elven 2013). The distribution of this species, both in North America and Eurasia, is characterized by numerous widely disjunct populations.
