Stilbe are small, single-stemmed or bulky, multi-stemmed shrubs . The leaves are in whorls of three to five. They are furrowed, linear-awl-shaped to narrowly lanceolate.

The inflorescences are dense, sessile spikes , old inflorescences remain as bald, scarred axes. The flowers are sessile and are accompanied by two opposite bracts . The calyx is usually hardened, tubular, slightly curved on the abaxial side (facing away from the inflorescence axis). It is set with five calyx lobes. The crown is tubular and divided into two lips. Two upper, upright and hairless tips are opposed to three narrower, also hairless tips. Inside the crown throat there is usually a dense ring of trichomes . The four stamens are slightly above the crown. The ovary is initially two-fold, but the abaxial ovary is stunted. The shape of the ovary is elongated and depressed. A single, basal ovule is formed in the non-stunted ovary compartment . The stylus is round and straight.
