Lobeliaceae, M. Thulin. Flora Zambesiaca 7:1. 1983

Morphology General Habit
Erect or rarely somewhat twining herb, 8–80 cm. tall, from a subglobose tuber c. 2 cm. in diameter; stem not or sparsely branched, ribbed below, sulcate in the inflorescence region, glabrous or sparsely pubescent above, rarely all plant pubescent.
Morphology Leaves
Leaves sessile or shortly petiolate, up to 30–110 x 3–25 mm., linear to broadly elliptic, acute or subacute at the apex, attenuate to cuneate at the base, serrate or serrate–crenate, glabrous or rarely short pubescent, mainly above; venation prominent beneath.
Morphology Reproductive morphology Inflorescences
Raceme dense or lax, up to 25 cm. long, sometimes branched; pedicels 1–6 mm. long, very finely pubescent or papillose; bracts leaf–like, diminishing in size upwards; bracteoles 1–3(7) mm. long, filiform to lanceolate, sometimes denticulate.
Morphology Reproductive morphology Flowers Hypanthium
Hypanthium broadly obconical, 10–nerved, shortly pubescent to papillose or glabrous.
Morphology Reproductive morphology Flowers Calyx
Calyx–lobes ± narrowly triangular, usually reflexed, 1·5–1·5 mm. long, with 1–3 pairs of teeth at the margin, glabrous.
Morphology Reproductive morphology Flowers Corolla
Corolla 9–16(20) mm. long, pale blue to mauve or purple, ± saccate at the base, split to the base into 2 lips, the upper 3–lobed but finally ± disintegrating, the lower divided into 2 free petals; all petals linear, glabrous or very rarely pubescent outside, white pubescent inside on the lower half or up to c. 2/3 of the length.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 4–7 mm. long; filaments linear, dilated and connate at the base,:±: pubescent; anthers elliptic–oblong, 1·6–3·2 mm. long, lanate with curled hairs c. 1·5 mm. long on the back of the connective, and at the tip with a tuft of hairs, ± 0–5 mm. long, by which the anthers are apically united at least in young flowers.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary semi–superior; style 2·5–5·5 mm. long.
Morphology Reproductive morphology Fruits
Capsule ovoid to subglobose, inferior part 2·5–4 mm. long, with 10 distinct nerves with ± transversal connections, membranous parts almost or entirely lacking; valves 3·5–6 mm. long.
Morphology Reproductive morphology Seeds
Seeds ± broadly elliptic in outline, ± compressed or irregularly angular, c. 1–1·5 mm. long, coarsely reticulate, brown.
