Type
Type: Sudan, Bongo, R. Lesi, Schweinfurth 4009 (K!, holo.)
Morphology General Habit
Spindly, erect perennial, 15–60 cm.
Morphology Stem
Stems simple or sparingly branched, ± creeping, rooting at the base, quadrangular, glabrous
Morphology Leaves
Leaves linear-lanceolate, 6–12(–30) mm long, 2–8(–10) mm wide, apex acute, margins entire or minutely toothed, scabrid-ciliate; lower leaves purple beneath, broader than the smaller and distant upper leaves, 3-veined
Morphology Reproductive morphology Inflorescences
Inflorescences capitate, ± 1 cm in diameter, up to 2.5 cm in fruit
Morphology Reproductive morphology Inflorescences Bracts
Bracts subulate
Morphology Reproductive morphology Flowers
Flowers subsessile
Morphology Reproductive morphology Flowers Calyx
Calyx 5 mm long, purple, prominently 5-angled, teeth triangular with setaceous apex
Morphology Reproductive morphology Flowers Corolla
Corolla 9–15 mm long, rich blue-purple, brown-tomentellous outside, upper lip slightly emarginate, lower lip deeply 3-lobed
Morphology Reproductive morphology Fruits
Capsule as long as the calyx, opening 1/3 of its length
Morphology Reproductive morphology Seeds
Seeds yellowish, angular, minute, nearly as broad as long.
Ecology
Swamps; 850–1300 m
Conservation
Least Concern (LC)
Note
Milne-Redhead & Taylor 10030 from Tanzania comes closest to T. schweinfurthii but has a more leafy stem and the leaves are on average broader (up to 1 cm). Fischer in B.J.B.B. 67: 378 (1999) has described this specimen as a new species (placed in synonymy here), but I (S.A.G.) feel that the material is insufficient to give it an independent status.
