[FTEA]

Lamiaceae (Labiatae), A.J. Paton, G. Bramley, O. Ryding, R.M. Polhill, Y.B. Harvey, M. Iwarsson, F. Willis, P.B. Phillipson, K. Balkwill, C.W. Lukhoba, D.F. Otieno, & R.M. Harley. Flora of Tropical East Africa. 2009

Type
Type: Senegal, Leprieur s.n. (G!, holo.)
Morphology General Habit
Aromatic annual or perennial herb, 30–50 cm tall
Morphology Stem
Stems erect, arising from a taproot, quadrangular above, rounded-quadrangular at base; indumentum of spreading hairs, with or without shorter spreading glandular hairs, hairs becoming antrorse on the inflorescence axis
Morphology Leaves
Leaves subsessile, often ascending, narrowly ovate to linear, 2–11 × 0.3–1.5(–3) cm, entire or shallowly serrate, apex acute, base cuneate; indumentum of short hairs, pubescent above, pubescent to tomentose beneath, with sessile glands
Morphology Reproductive morphology Inflorescences
Inflorescence lax with the mainly 6-flowered verticils 1.5–3 cm apart; bracts brightly coloured, pink or white, pubescent with sessile glands, forming a conspicuous terminal coma composed of bracts from more than two nodes, broadly ovate to elliptic, 3–20 × 3–10 mm; bracts rarely absent in mature fruiting specimens
Morphology Reproductive morphology Flowers Calyx
Calyx purplish, 4–8 mm long at anthesis; fruiting calyx 9–12 mm long; indumentum of pubescent glandular or eglandular hairs
Morphology Reproductive morphology Flowers Corolla
Corolla white or lilac, 12–15 mm long, anterior lip horizontal or deflexed; tube 10–11 mm long, straight, dilating at throat
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens exserted 3–7 mm, anterior glabrous, posterior with minute scattered hairs
Morphology Reproductive morphology Fruits
Nutlets brown, broadly ovoid, 2 mm long, smooth with a small dorsal ridge, producing mucilage when wet
Figures
Fig 26, p 176
Ecology
Brachystegia or Commiphora woodland, dry sandy grassland, streamsides; 250–1250 m
Conservation
Least concern; widely distributed
Note
This species approaches S. welwitischii which differs in the elliptical to ovate leaves which are up to 3.5 times as long as broad. The rootstock of S. welwitischii tends to be more conspicuous than that of S. bracteosa which has a tap root. The two taxa are normally easy to differentiate. Milne-Redhead & Taylor 8047 from Songea is somewhat anomalous, having its lower leaves elliptic but the upper leaves and those of all other specimens of S. bracteosus are linear or narrow ovate.
Distribution
Range: Widespread in tropical Africa from Senegal to Sudan, and south to Namibia and South Africa Flora districts: T5 T6 T7 T8
