Plants: taproot thick, with dense tufts of basal rosettes of leaves. Flowering stems simple or sparingly branched, sturdy, 10–20(–30) cm, usually with 2–3 pairs of lanceolate leaves, internodes equaling or shorter than leaves.

Flowers 8–16 mm diam.; calyx campanulate to ovoid, 10–20 mm in fruit, 1–11/2 times longer than broad. 2n = 24 (Siberia), 48.

Discussion

Subspecies involucrata, a circumpolar and panarctic taxon, is quite variable. In the western arctic there is a tendency towards larger, almost glabrous, leafier plants that have a markedly ovoid mature calyx to 20 mm. These plants often lack purple pigment and have been named subsp. elatior, but they probably do not warrant taxonomic recognition.
