Descriptions

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

Morphology General Habit
Plant 2–6 m. tall in flower, ± erect, suckering from the base.
Morphology Stem
Stem 4–8 cm. thick at base, terete, hollow, pubescent above.
Morphology Leaves
Rosette–leaves of unflowered plant sessile, ± narrowly oblanceolate, up to 50 x 10cm., acute or acuminate at the apex, attenuate at the base, weakly pubescent on both sides, more densely pubescent on veins beneath; margin serrate to doubly serrate or denticulate; venation protruding beneath.
Morphology Reproductive morphology Inflorescences
Inflorescence up to 3–4 m. long, lax, branched with a terminal many–flowered raceme and usually many axillary racemes on leafy peduncles below; pedicels 8–25 mm. long, spreading, pubescent; upper bracts linear to lanceolate and 10–20 mm. long, lower bracts ovate and up to 30–40 mm. long; bracteoles usually in upper part of the pedicel, linear, 1·5–4 mm. long.
Morphology Reproductive morphology Flowers Hypanthium
Hypanthium obovoid, 10–nerved, ± pubescent.
Morphology Reproductive morphology Flowers Calyx
Calyx–lobes narrowly triangular, flat, 10–16 mm. long, weakly pubescent on both sides, entire.
Morphology Reproductive morphology Flowers Corolla
Corolla 25–35 mm. long, mauve or pinkish purple, split to the base on the back, ± papillose–pubescent outside and pubescent inside on the bottom of the tube; two lateral petals linear, united with middle petals below, but often becoming free to the base; three middle petals soon splitting up at the apex into three ± 6 mm. long lobes.
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments linear, somewhat dilated at the base, connate almost to the base and forming a firm tube, papillose mainly towards the base, free from corolla.
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anther–tube 6–7 mm. long, all anthers glabrous at the apex, but sparsely pilose on the back.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary subinferior.
Morphology Reproductive morphology Fruits
Capsule obovoid to subspherical, 10–15 mm. long, 10–nerved, weakly pubescent or glabrescent with two short valves.
Morphology Reproductive morphology Seeds
Seeds ± broadly elliptic–oblong in outline, compressed, narrowly winged along one margin, 0·6–0·7 mm. long, finely striate, pale brown.
