Shrubs or herbs, often geoxylic, usually aromatic; stems branched; leaves simple; inflorescence thyrsoid with cymes sessile, 1-3-flowered; bracts caducous, coloured, but small and inconspicuous; calyx tubular, straight or curving slightly upwards, 5-lobed, either radially symmetrical with lobes equal, lanceolate or strongly 2-lipped (1/4), lobes unequal, posterior rounded, not decurrent, nor strongly curving upwards, lateral lobes deltoid, anterior subulate, throat open; corolla strongly 2-lipped, 5-lobed (4/1), white, pink or purple, posterior lip ascending with median lobes smaller and exceeding lateral lobes, usually truncate, anterior lip horizontal or slightly deflexed, slightly concave, corolla-tube straight or slightly curved, dilating slightly towards throat; stamens 4, exserted, posterior pair attached just below midpoint, ciliate or glabrous, inappendiculate, anterior attached at corolla throat, connate; style bifid to clavate; stigma-lobes equal, linear or more rounded; disc 4-lobed with anterior lobe larger, nutlets ovoid, smooth with a prominent dorsal vein, mucilaginous or not.  Ten species in South Africa and Zimbabwe, grassland or forest margins, often in rocky areas.  Syncolostemon is very closely related to Hemizygia, but differs consistently in the lack of a decurrent posterior calyx-lip.  The genera may need to be merged
