A native of the Cape of Good Hope. 
Stem a few inches high, and half an inch thick below the 
leaves. Leaves fifteen to twenty, laxly aggregated, quadrifariously 
arranged and twisted obliquely, and much decurved, oblong- 
spathulate, the lower ones three to four inches long by more than 
an inch broad three-quarters of the way up, a quarter of an inch 
thick in the middle, very glaucous and covered all over, like the 
rest of the plant, with fine pubescence. Flowering stem exclusive 
of the panicle under a foot high, firm, erect, with a few pairs of 
erect much-reduced leaves adpressed to it. Panicle regularly 
pyramidal, six to nine inches long; the lower branches erecto- 
patent downwards; the bracts small, lanceolate, very fleshy ; the 
minute flowers in densely-rounded heads at or near the summit 
of the branches. Calyx with a campanulate cup, subtended by a 
boat-shaped bracteole, and five oblong obtuse divisions. Petals 
panduriform, exceeding the sepals, yellowish green, permanently 
connivent, crowned each by a conspicuous yellow gland. Stamens 
perigynous, with filiform filaments. Hypogynous scales quadrate, 
emarginate. Carpels a little shorter than the petals, with sessile 
stigmas.
