Verticillasters many flowered, in continuous or rarely interrupted terminal spikes; bracts slightly shorter to as long as flowers. Flowers sessile. Calyx campanulate, hairy outside, glabrous inside, short 5-toothed, usually without crystals. Corolla exserted, tube gradually widened at apex, limb 4-lobed; lobes subequal, posterior lobe entire or emarginate. Stamens 4, exserted; filaments long, subequal, straight, bearded; anthers subglobose, 1-locular. Style subequal to stamens, apex 2-cleft; lobes equal, subulate. Disc ringlike, subentire.
