Venation: secondary veins 11–15 pairs, 6–14 mm apart from each other, forming angle 65°–70° to midvein, prominent in both surfaces, arcuate near margin; intersecondary veins present, one or two per intercostal area, much thinner than secondary veins, distal course basiflexed,> 50 % of subjacent secondary length; tertiary veins percurrent sinuous; intramarginal vein absent. Inflorescences: ♂ lax cyme with 3 basal branches and up to 9 flowers, lacking terminal flower, ♀ dichasium, lenticels absent. Pedicels 12–30 mm long, coloration not seen, distal and proximal portion with same gauge, proximally or in middle articulated in all flowers of dichasia; calyptrae and lenticels absent.

Distribution — Brazil (Minas Gerais). Fig. 70.

Conservation status — Endangered (EN, Marinho & Beech 2019).

Recognition and discussion — Tovomita salimenae has leaves similar to those of T. longifolia , but the flowers are similar to those of T. leucantha . When sterile, T. salimenae can be distinguished from both species by the copper-coloured veins ( Fig. 14F) on the leaf abaxial surface and the number of secondary veins (11–15 vs 8–10 pairs in T. longifolia and 22–40 pairs in T. leucantha ). The short, subclavate stamens of T. salimenae also occur in T. guianensis , but they are in larger number (40–45 vs 15–20 in T. guianensis ). In addition, while T. salimenae is endemic to the southeastern part of the state of Minas Gerais, in southeastern Brazil ( Fig. 70), T. guianensis , in the Atlantic forest, occurs only in northeastern Brazil (Fig. 46).
