Information
Small spreading, diffusely branched, glab-rescent bushes (chamaephytes) up to c. 0,3 m tall. Rootstock woody, gnarled, knobbly (the knobs presenting remains of swollen bases of annual stems); roots woody, long, in­itially covered by roothairs. Stems several, erect, with long internodes up to 60-100 mm long, 1-2 mm in diam. Leaves with lamina linear, flat, 80-100 x 4-10 mm, attenuated at base into a pseudo-petiole, white-punctu-late; sheath membranous, sub-auriculate. Flowering spathe solitary (rarely 2), terminal, sessile or nearly so, fused, shortly triangular, 15 mm long, 10 mm broad, apex short, acute, minutely puberulous and with scattered white setae. Cyme solitary. Flowers small, petals blue or white ("pink" fide Galpin 808). Sepals ovate, c. 5 mm, membranous, upper minute. Petals: upper ones rounded, c. 15 mm, lower one minute. Stamens typical, the anthers oc­casionally with dark margins, the central semicircular; staminodes with yellow, bulbous antherodes. Capsule with globose, shiny, cream-coloured locules; seeds globose, 5 mm in diam., smooth, farinaceous, dorsal seed occasionally aborted.
Habitat
This species was usually placed under C. livingstonii (no. 13), but is a more slender bush found in rocky habi­tats. The leaves narrow gradually below into a pseudo-petiole, whereas in C. livingstonii they widen below and then narrow abruptly into the sheath.
Use
