Abstract: With about 70 species Virola, is the largest genus of Myristicaceae in the Neotropics, the genus ranked in the top ten genera of abundance across Amazonia. Ten new species are proposed in this striking genus, which are described based on morphology, and are illustrated. The new species were discovered thanks to herbarium specimens collected mainly in the 1980s and 1990s when field documentations were more active. The new species come from Colombia (V. calimensis sp. nov., V. cogolloi sp. nov., V. excisa sp. nov., V. tuckerae sp. nov.), Ecuador (V. alvaroperezii sp. nov., V. bombuscaroensis sp. nov., V. calimensis, V. excisa, V. yasuniana sp. nov.), Peru (V. aguarunana sp. nov., V. cumala sp. nov., V. excisa, V. parkeri sp. nov.), and Brazil (V. excisa, V. yasuniana). Additionally, a lectotype is designated for V. macrocarpa, a name used to identify some specimens of the new species here described, and V. kwatae is reported for the first time for Brazil. We provide a comparation table between the new species and the species that is morphologically close to it, a preliminary list of species for the genus, and notes of how the new species were treated in floras, checklists, or collections that need more study and herbarium specimens.

Two new species of Otoba (Myristicaceae) from Colombia https://phytokeys.pensoft.net/article/64564/ PhytoKeys 178: 147-170

DOI: 10.3897/phytokeys.178.64564

Authors: Daniel Santamaría-Aguilar, Laura P. Lagomarsino

Abstract: Otoba is the third largest genus of Myristicaceae in the Neotropics with 12 species, nine of them native to Colombia. Two new species from the department of Antioquia, O. scottmorii sp. nov. and O. squamosa sp. nov., are described and illustrated. Otoba scottmorii occurs in humid, lowland forests, while O. squamosa occurs in premontane forest. Previously, Otoba scottmorii was confused with O. acuminata (which here is considered restricted to Costa Rica and Panama), while O. squamosa was confused with O. gordoniifolia. The similarities and differences between these and other species are discussed.

A taxonomic synopsis of Virola (Myristicaceae) in Mesoamerica, including six new species https://phytokeys.pensoft.net/article/37979/ PhytoKeys 134: 1-82

DOI: 10.3897/phytokeys.134.37979

Authors: Daniel Santamaría-Aguilar, Reinaldo Aguilar, Laura P. Lagomarsino

Abstract: A taxonomic synopsis of Virola (Myristicaceae) is presented for Mesoamerica. Fourteen species are recognised, amongst them six are described and published as new, based on morphology: V. allenii D.Santam. & Aguilar, sp. nov. from Costa Rica, V. otobifolia D.Santam., sp. nov. from Panama and V. amistadensis D.Santam., sp. nov., V. chrysocarpa D.Santam. & Aguilar, sp. nov., V. fosteri D.Santam., sp. nov. and V. montana D.Santam., sp. nov. from both Costa Rica and Panama. Additionally, a lectotype is designated for V. koschnyi, accompanied by an epitype in view of the fragmentary material. Finally, we recognise V. laevigata and V. nobilis as morphologically distinct species, though these are frequently considered synonymys of V. guatemalensis and V. surinamensis, respectively. Of the fourteen accepted species, twelve of them are endemic to Mesoamerica, while the remaining two species (V. elongata and V. sebifera) extend into South America. Illustrations, species diagnoses and distribution maps for each species are provided, as is an identification key to all species.
