Leaves subsessile; blade broadly elliptic to obovate or rotund, larger blades in mid-stem region, 5-22 × 2-8 mm, apex round and obtuse, rarely broadly acute, pubescence ciliate and strigose, hairs long and eglandular, mixed with shorter eglandular hairs, colorless to somewhat fuscous; proximal leaves not strongly marcescent, blade oblanceolate, often broadly so, spatulate. Inflorescences 1-3-flowered, lax cymes, with patent, multicellular, long, glandular hairs; proximal bracts broadly lanceolate, pubescence as leaves; distal bracts narrowly lanceolate, margins narrow, scarious, glandular-pubescent. Pedicels ± straight or somewhat curved at apex, 5-45 mm, 1-4 times as long as sepals (rarely longer), pubescence long and glandular. Flowers: sepals narrowly lanceolate, 8-11 mm, margins narrow, apex acuminate, hairs ascending, long, glandular and eglandular; petals 12-18 mm, 1-2 times as long as sepals, apex 2-fid; stamens 10; styles 5. Capsules broadly conic, straight or almost so, 14-18 mm, 1.5-2 times as long as sepals, teeth 10, ± erect, margins convolute. Seeds red-brown, 1.1-1.3 mm diam., tuberculate; tubercles acute; testa not inflated, closely enclosing seed. 2n = (54) 108.
