Verticillasters in dense capitula or spikes, or widely spaced; bract margin acute serrate or spinescent, rarely entire. Calyx tubular or campanulate-tubular, straight or slightly curved, 15-veined, 2-lipped, 5-toothed; teeth subequal or sometimes middle tooth of upper lip wider than lateral teeth, sinuses with a thickened fold. Corolla blue-purple, pink, or violet, rarely white, slender basally, dilated at throat, 2-lipped; upper lip straight or slightly curved; lower lip 3-lobed, middle lobe largest. Stamens 4, posterior 2 longer than anterior 2; anthers glabrous, rarely hairy, cells 2, divaricate at nearly 180°. Style apex equally 2-cleft. Nutlets oblong, smooth, sometimes mucilaginous.
