Annual or perennial herbs (in
ours). Stems not twining. Leaves alternate. Bracteoles minute, ± linear, rarely 0. Flowers usually resupinate, zygomorphic. Corolla
usually 2-lipped with upper lip 2-lobed, lower 3-lobed (rarely all petals form a single lip). (The terms 'upper' and 'lower'
assume flowers are resupinate). Anthers (5) united into a tube; the two lower or all of them penicillate at tip, the two lower ones somewhat shorter than others. Ovary inferior to
± superior, 2-locular. Stigma lobes 2, surrounded
by a ring of hairs. Fruit a capsule dehiscing by
2, rarely 4, apical valves; or, rarely indehiscent. Derivation of name: after Mathias de L'Obel (Lobelius) (1538-1616), Flemish botanist, traveller and plant collector. (Clarke, Charters & Moll-Ed., 202, 2016). Worldwide: c. 300 species in tropical and warm areas, a few temperate. Rwanda: 11 taxa. |
