Information

Herbs, subshrubs or shrubs. Leaves in pseudowhorls of 4, the upper leaf-pair in each whorl smaller than the other, sessile or almost so. Flowers in spike-like cymes, each flower subtended by a bract or the cyme reduced to a solitary seemingly terminal flower mostly supported by (3–)4(–5) pairs of bracts; bracts leathery, usually toothed; bracteoles 2 or absent, usually narrow. Calyx divided to the base into 4 lobes, the upper lobe usually longer than the others. Corolla 1-lipped; tube short; limb split on the back to give a 3–5-lobed lower lip. Stamens 4, the upper pair with linear filaments, the lower pair with broad and flattened filaments that are usually divided at the top into a short branch bearing the anther and a tooth-like appendage; anthers 1-celled. Ovary 2-celled with 2 ovules per cell. Capsule ovoid-ellipsoid, woody, 2(–4)-seeded. Seeds flattened with long branched hygroscopic hairs.
