Characteristics

Plants glabrous, up to 60 cm high. Roots many, somewhat fleshy or thin, often with a lanate pubescence of root hairs. Rhizome small, irregular, woody. Squamae narrow tubular, membranous, brown, several surrounding each leaf-and scape-base separately but none surrounding a shoot. Leaves many, terete, up to 40 cm long, 3 mm in diam., erect or drooping, often glutinous from secretions of sub-epidermal glands situated in longitudinal lines. Inflorescence a divaricate much branched raceme, branches either alternate or the first three arising trichotomously from a clavate apex, the following branches alternate, laxly flowered; bracts ovate, ca. 3 mm long, membranous, white with a brown keel; pedicels up to 6 mm long, erect in bud, pendulous during anthesis, erect in fruit. Flowers pendulous with perianth 1 cm in diam. Recurved from near the base, forming a “ball” around pedicel, white, dark keeled, with 2yellow spots near the base, scentless, producing much nectar; 3 outer stamens scabrid, 3 inner forming a tube, curving outwards above ovary and there yellow and densely, retrorsely scabrid; the basal area touching the ovary, smooth with lateral, and dorsal fringes; ovary with ca. 10 ovules per cell. Capsule ca. 6 mm long, globose, dry. Seed dark brown, angled.
More
Inflorescence usually 1, erect, branching divaricately above the middle; branches all alternate or the first 3 arising trichotomously from a club-shaped peduncle apex with subsequent branches alternate; peduncle stout, 2–8 mm in diameter, terete, or ± club-shaped at the apex, glabrous; bracts c. 3 mm long, ovate, membranous, white with a brown keel; flowers many, racemosely arranged and spaced on terminal branches; pedicels 2–11 mm long, erect in fruit.
Leaves of 2 kinds; outer leaves reduced to chartaceousbrown sheaths (squamae), 2 or more forming a persistent narrowly tubular base enveloping each leaf base and the peduncle base; inner leaves many, up to 25 cm long and 3 mm in diameter, ± terete, erect or drooping, often glutinous, glabrous.
Perianth segments c. 11 mm long, recurved from near the base, white, dark-keeled, with 2 yellow spots near the base; the 3 outer filaments erect and muricate, the 3 inner curving outwards above the ovary and densely shaggy-scabrid in the upper portion with retrorse yellow hairs.
Perennial glabrous herb, erect to ± decumbent, up to 90 cm tall from a small woody rhizome, acaulescent; roots many, somewhat fleshy, usually ± swollen and tapering to the tip or narrowly fusiform or terete and ± fibrous, often with root hairs producing a felted covering.
Capsule smooth or slightly rugose, without tubercles, sparsely yellow-flecked, up to c. 5.5 mm long, subglobose to somewhat 3-angular.
Seeds c. 2 per locule, sharply angled, c. 1.5 mm long, white-spotted becoming greyish-black when mature.
Like T. revoluta but leaves terete, hairless, often glutinous and bearing sand.
