Tovomita clusiiflora (Ducke) L. Marinho , comb. nov. ( Fig. 1A–D ).

Basionym: — Tovomitidium clusiiflorum Ducke, Arq. Inst. Biol. Veg. 2(1): 62, 7. 1935. Type:— BRAZIL. Amazonas: São Paulo de Olivença, habitat in silva mediocri terris altis prope São Paulo de Olivença ( Rio Solimões , in civitate Amazonas), 3 October 1931, bud and fl. ♂, A. Ducke s.n. [RB No. 25051] (holotype: RB [barcode RB00539011 !]; isotypes: K [barcode K000815954 !], US [barcode US 00114307 photo!]).

= Tovomita froesii Maguire, Phytologia 39(2): 76. 1978, syn. nov. Type:— BRAZIL. Amazonas: “ São Paulo de Olivença”, upper Jandiatuba , 12 January 1949, fr., R. L. Froés 23887 (lectotype [designated here]: NY [barcode NY00076045 !]; isolectotypes: IAN 2 -sheets No. 15834!, 42820!; NY [barcode NY00579023 !]; P [barcode P01901229 !]).

Notes:— The description of Tovomitidium clusiiflorum was based on a staminate specimen with buds in pre-anthesis and open flowers, which could have been erroneously interpreted as having incompletely covered buds. About forty years later, Maguire (1978) described Tovomita froesii based on a fruiting specimen. The type localities of both species are approximately the same, in the municipality of São Paulo de Olivença, western Brazilian Amazon, and their vegetative descriptions are quite similar: blade size 25–30 × 10–15 cm in T. froesii and 22–36 × 8–15 cm in T. clusiiflorum ; number of secondary veins 17–20 in T. froesii and 16–20 pairs in T. clusiiflorum (not published, but measured from the type); and arrangement of tertiary veins (scalarifom on both species). Thus, we consider Tovomita froesii as a synonym of the new combination Tovomita clusiiflora .
