Derived from O. Ryding (2006) Plectranthus. Flora of Somalia 3:349-355
Plants herbs or shrubs. Inflorescences thyrse-like (in species from Somaliland and Somalia), open or dense; bracts smaller and usually clearly differentiated from the leaves, often deciduous; cymes of individual thyrses with 1-many flowers, sometimes distinctly pedunculate; bracteoles absent. Flowers pedicellate; pedicels attached opposite the upper lip of the calyces; calyces funnel-shaped, 5-lobed, usually more or less upcurved, sometimes almost rotate, lower lobes usually longer and/or narrower than the lateral lobes, lateral lobes lanceolate or deltoid, upper lobes somewhat enlarged, often decurrent along the lateral part of the tube; corollas strongly 2-lipped, tubes usually bent near their base, lower lips boat-shaped, much longer than the upper lips, upper lips (3-)-4-lobed, almost flat; stamens attached near the corolla tube mouths and close together, free to unted to beyond midlength, usually becoming as long as the lower corolla lips; anthers 1-celled; style branches equally long. Nutlets subglobose to shortly ellipsoid, glabrous, usually glossy.
Coleus, as interpreted by Paton et al. (2018) includes about 300 species and grows in warmer parts of both the Old and New World. There are 15 species of Coleus treated in the Flora of Somalia, all of them being treated as members of Plectranthus. The above description is modified from that of Plectranthus in the Flora based on information in Paton et. (2018).
Note: GBIF records include introduced and cultivated plants. Consequently, the distribution shown often differs from statements about a taxon's native distribution.
