description
Description. Trees 8 - 50 m high (Fig. 268 B); bark rugose, with lenticels, sometimes exfoliating in irregular layers. Stipules obovate to lanceolate-falcate, sericeous, fulvous, caducous. Leaves bipinnate, pubescent, fulvous (Fig. 265 E); leaf glands near the base of the petiole and sometimes between the pairs of pinnae; paraphyllidia present or absent; pinnae 10 - 30 pairs; leaflets 40 - 80 pairs, linear, asymmetrical. Inflorescence units homomorphic or heteromorphic capitula (Fig. 265 F), 2 - 5 - fascicled in leaf axils or amongst the branches below the coeval leaves, in the heteromorphic ones the terminal flower is larger than the others, and the staminal tube is exerted. Flowers 5 - merous; calyx gamosepalous, campanulate; corolla gamopetalous, campanulate, lobes triangular, fulvous villose; stamens numerous, the filaments basally united into a tube; pollen in 16, 28 - celled polyads; ovary sessile, ovoid, fulvous villose. Fruits indehiscent, reniform auriculiform, sometimes twisted, laterally compressed, puberulent (Fig. 266 F). Seeds ovoid, ellipsoid or obovoid; pleurogram present.

distribution
Included species and geographic distribution. Three species known to date, R. glaziovii (Benth.) A. R. M. Luz & E. R. Souza, R. oldemanii (Barneby & J. W. Grimes) A. R. M. Luz & E. R. Souza and R. schomburgkii (Souza et al. 2022 b), from the south of Mexico to Bolivia, to 1100 m elevation. Robrichia glaziovii is endemic to eastern Brazil (Morim et al. 2020), R. oldemanii occurs in French Guiana and northern Brazil (Fernandes 2023) and R. schomburgkii is present from the south of Mexico to Bolivia (Fig. 271).
etymology
Etymology. The name of this genus is composed of the initial parts of two names " Rob " and " Rich ", which Barneby and Grimes (1996) chose to commemorate the brothers Robert and Richard Schomburgk, German naturalists who sampled the Guyana flora in the 19 th century.
