Morphological description

Plant 9-10 in. high, branching at the base only; stems erect from a slightly decumbent base, slender, glabrous with 2 pubescent lines, leafy; leaves numerous, erect, 2-3.5 in. long, 0.5-1 lin. broad, linear, acute, revolute along the margins, glabrous; umbels several to a stem, subaxillary, shortly pedunculate or subsessile, subglobose, 7-10-flowered; peduncles 1-2.5 lin. long; bracts about 1.25 lin. long, subulate or filiform; pedicels 2-2.5 lin. long, minutely puberulous with curved hairs; sepals 1-1.25 lin. long, 0.5 lin. broad, lanceolate, acute, minutely puberulous, spreading or perhaps slightly recurved; corolla about 2.5 lin. in diam., bell-shaped, 5-lobed almost to the base; lobes erect or but slightly spreading, 2 lin. long, 1 lin. broad, oblong-lanceolate, obtusely pointed, slightly concave at the base, recurved and slightly thickened at the apex, and somewhat reflexed along the margins, glabrous outside, very minutely velvety at the thickened apex within; corona-lobes arising at the very base of the staminal column and incurved over it, 1.5 lin. long, linear-falcate when viewed sideways, fleshy, flat on the face, very convex on the back; staminal column about 1 lin. long; filament part above the insertion of the corona-lobes about 0.2 lin. long; anthers quadrate, erect, their appendages broadly ovate, acute, erect, slightly indexed at the tips over the rim of the style-apex; their wings broadened into a triangular projection a little below the middle; pollen-masses obliquely deltoid, shaped something like a ham of bacon; style-apex pentagonal, excavated, not exceeding the anther-appendages; follicles not seen.

Perennial, geophytic herb, erect, 228-380 mm high; stems solitary. Leaves erect, linear 50-90 x 1-2 mm, base cuneate, apex acicular, margins revolute; midrib prominent below; sessile, ± apetiolate. Inflorescences subaxillary, subglobose, up to 7 per stem, 1-7-flowered. Flowers with pedicels 4-5 mm long. Corolla erect but spreading slightly, appearing campanulate, straw-yellow-green; lobes free to base, oblong-lanceolate, 4 x 2 mm, thickened and slightly recurved at apex, margins slightly revolute. Staminal column ± 2 mm high, not stipitate. Corona white; lobes fleshy, ovate or teardrop-shaped, 3 x 1 mm, tip attenuate and inflexed over style-stigma-head, outer surface convex.

Diagnostic description

This plant is so exactly like Krebsia stenoglossa and Sehizoglossum periglossoioles in the dried state, that it is scarcely possible to distinguish them unless their flowers are dissected, when the great differences of their corona-lobes, staminal column and pollen-masses are convincing enough of their distinctness. Probably when alive they are more easily distinguished. From: Brown, NE. 1907. Asclepiadeae. In: WT Thiselton-Dyer (ed.), Vacciniaceae to Gentianeae. Fl. Cap. (Harvey) 4(4): 518-672.
