Spruce 3391 (P [ P00093877 ]!; isolectotypes: BM [ BM000047401 ] photo!, BR [ BR0000005915514 ] photo!, G [ G00355504 ] photo!, G photo!, GH [ GH00067918 ]!, K [ K000488540 ]!, K [ K000488541 ]!, MPU [ MPU014286 About MPU ] photo!, NY [ NY00578999 ]!, P [ P00093876 ]!, RB [ RB00539009 ]!, TCD [ TCD0000899 About TCD ] photo!).

Description — Shrubs or trees up to 6 m tall, prop roots inconspicuous; exudate yellow, scarce. Petioles 1–1.5 cm long, green, smooth, lenticels absent. Leaf blades 9.7– 24 × 4–10 cm, dark brown in sicco, black dots absent, chartaceous, obovate, base decurrent, apex rounded to acuminate; papillae and lenticels absent, fungal spots sometimes present; exudate canals inconspicuous. Venation: secondary veins c. 35 pairs, 2.5–3 mm apart from each other, forming angle c. 70° to midvein, prominent in both surfaces, straight near margin; intersecondary veins present, one per intercostal area, similar to secondary veins, parallel to major secondary,> 50 % of subjacent secondary length; tertiary veins percurrent inconspicuous; intramarginal vein absent. Inflorescences: ♂ lax cyme with 5 or 7 basal branches and up to 100 flowers, lacking terminal flower, ♀ dichasium, lenticels absent. Pedicels 5–7 mm long, green, not articulate; calyptrae and lenticels absent. Floral buds 5–7 mm long, narrowly oblong, apex acute, lenticels absent, blackened in sicco. Sepals 2, 5–7 × 1.5–2 mm, narrowly oblong, apex acute, green; petals 4, c. 5 × 1–1.2 mm, narrowly oblong to oblong, position not seen, apex acute, white. Staminate flowers: stamens c. 50, 5.5–7 mm long, heterodynamous; filaments filiform-terete, white; anthers 0.2–0.3 mm long, connective not exceeding thecae; pistillode not seen. Pistillate flowers not seen. Capsules fleshy, 1.6–2 × 1.4–1.5 cm, 4-septate, spheroid to ovoid when closed, rostrum present, 3–3.5 mm long, epicarp smooth, green when immature, mature fruit and mesocarp coloration not seen; sepals, petals, staminodes and stigmas persistent. Aril coloration not seen.

Iconography — Illustration available in Engler (1888: 98).

Distribution — Brazil (Amazonas), Colombia (Amazonas, Meta, Guaínia), Ecuador (Orellana), Peru (Loreto), Venezuela (Amazonas). Fig. 80.

Conservation status — Data Deficient (DD, Marinho & Beech 2019).

Nomenclatural notes — Among the two specimens housed at P — possibly used by Triana to describe the species — P00093877 bears more floral buds, which we chose as lectotype .

Recognition and discussion — Tovomita tenuiflora can be recognized by the long leaves with c. 35 pairs of secondary veins and flower buds with an acute apex and blackened in sicco. Several herbarium specimens of T. tenuiflora have been labelled as T. carinata , possibly due to the similar floral buds also blackened in sicco. The two species can be distinguished by leaf texture (chartaceous vs subcoriaceous in T. carinata ), floral bud apex (acute vs usually rounded in T. carinata ) and, especially, by the c. 50 filiform-terete stamens (fl. ♂) and staminodes (fl. ♀) (vs <35 terete stamens/staminodes in T. carinata ).
