Stems spreading and diffuse, much branched, mainly from base, pubescent with glandular hairs, eglandular hairs, or mixture. Leaves recurved and somewhat lax; blade dark green to yellowish green, linear-lanceolate, mostly 20--30 ´ 0.5--1.0 cm (distal leaf blades equal to or narrower than sheaths when sheaths opened, flattened), sparsely to densely pubescent. Inflorescences terminal, solitary, or more commonly also with lateral, pedunculate inflorescences; bracts foliaceous, similar to leaves in form, sparsely to densely pubescent. Flowers distinctly pedicillate; pedicels 2.5--4.5 cm, densely pubescent with medium to long, glandular hairs; sepals 6--11 mm, densely pubescent with glandular hairs like those of pedicels, occasionally with a few eglandular hairs; petals distinct, pink to dark blue, broadly ovate, not clawed; stamens free; filaments bearded.
