Trees, 13– 18 m. Leaves with 9–12 pairs of pinnae; 10–14 pairs of leaflets; petiolar nectary 1, verruciform; leaflets 6– 14 × 5–8 mm, obovate, proximal leaflets oblong to elliptic, chartaceous, subconcolor, upper surface yellow-pubescent, lower surface yellow-tomentulose, unilateral tuft of trichomes on the lower surface present and prolonged up to the 3rd pair of basal veins. Inflorescences of simple thyrsi, brownish; cymulae of solitary to ternate spikes; spikes 8–10.5 cm long. Flowers monoclinous, corolla yellow-sericeous, yellow. Fruit a nucoid legume, straight, flat-compressed, seeds slightly prominent, valves woody, inconspicuously nerved. Distribution and Habitat — Stryphnodendron flavotomentosum is known only in the Atlantic Forest domain from Western Espírito Santo state, municipalities of Baixo Guandu and Marilândia, where it has been collected in forested slopes and river ravines. Conservation —Data Deficient (DD) [AOO = 8 km ², EOO not measurable]. The species is known only from a few collections and the area where it occurs is considered very poorly collected. However, recent collecting efforts have revealed populations of several taxa previously known from limited herbarium samples, and it is possible that intensive field work might increment the available sampling of S. flavotomentosum and broaden its current distribution. Phenology — C ollected with flowers and fruits in December. Selected specimens examined: — BRAZIL. Espírito Santo: Aracruz, atrás do tanque de efluentes, Fábrica, 02 February 1995, fr., J.N.
