Habit
Dwarf subshrubs; stems nearly erect to ascending, 3-8 dm long, short internodes of leafy portions alternating with elongate internodes of rhizomatous portions, presumably due to growth in surrounding bryophyte and other tussock vegetation, unbranched or branched from near base, also sometimes producing slender, short, stolon-like innovations, glabrous.
Leaves
Leaves clustered on short, exposed stem portions, soft-coriaceous, broadly ovate to ovate-suborbicular or rarely subcordate, 1.5-9 cm long, 1-2(-2.8) cm wide, margins callose-serrate, the teeth slightly incurved, apex obtuse to bluntly acuminate, base broadly cuneate or rarely subtruncate, petioles as long as or longer than blades, 0.8-6.5 cm long, stipules thin, deltate-ovate to ovate, 5-12 mm long, margins fimbriate, the lateral teeth (1-)1.8-4 mm long, apical teeth usually longer.
Flowers
Flowers fragrant, apparently all chasmogamous, (1)2(-5) per peduncle, on peduncle-like scapes consisting of 1 to several leafless internodes, peduncles (25-)30-150(-250) mm long or perhaps even longer, pedicels subequal in a single inflorescence, (10-)15-55 mm long, bracteoles above middle; sepals narrowly deltate-lanceolate, upper one 6-7 mm long, lateral ones ca. 5.3-8 mm long, lower ones ca. 5.5-7 mm long, glabrous; petals dark violet with paler tinges to pale blue or rarely nearly white, upper ones 12-14 mm long, lateral ones ca. 13-15 mm long, lower one ca. 15-16 mm long; stamens 3.5-4 mm long, connective of lower ones prolonged into a rhombic structure 1.3-1.5 mm long.
