Plants robust, rhizomatous, lanate, forming colonies, saxicolous. Rhizome short and thick, vertical, bearing long, thick roots, placed close together at the base, c. 5 mm in diam., in turn producing active, thin, branched rootlets. Leaves in basal clusters, sub-rosulate, c. 6, linear-acuminate, c. 120-300 x 13-26 mm, flat, somewhat fleshy, glabrous and shiny above, lanate below, with long, thin, appressed, white hairs. Fertile shoots arising below (sterile) leaf-cluster, procumbent, many-noded, upper bearing dense, lanate cymes enclosed by ovate, falcate spathes; bracteoles small. Flowers typical. Calyx with erect hairy lobes, c. 10 mm long. Corolla 15(-20?) mm long, blue. Capsule narrow with an apical tuft of setae; seeds oblong-globose, c. 2 mm long, typical.
