Within the genus 27 species are recognized, 4 of which are new to science. Most of the species are occurring in tropical South America, whereas a few (6) are found in Mexico and Central America and two in the West Indies (Greater and Lesser Antilles). A key to all species is provided. The treatment includes chapters about the history of the genus and morphology. All species are fully described, including full synonymy, notes on distribution and ecology, field observations (when available), vernacular names (when given), and mostly short notes about relationships of the species concerned. For each species a distribution map is made. At the end of the revision a complete list of vernacular names is included.}, keywords = {Annonaceae, Neotropics, Oxandra, taxonomy, Vernacular Names}, doi = {10.3767/000651916X694283}, author = {Junikka, L. and Maas, P.J.M. and Maas-van de Kamer, H. and Westra, L.Y.TH.} } @article {5289, title = {A taxonomic survey of Guatteria section Mecocarpus including the genera Guatteriopsis and Guatteriella p.p.

These species were placed by Fries in Guatteria sect. Mecocarpus (Fries 1939) (the name derives from Ancient Greek \&$\#$956;\&$\#$951;\&$\#$954;\&$\#$969;\&$\#$957; = Poppy and \&$\#$954;\&$\#$945;\&$\#$961;\&$\#$960;\&$\#$959;\&$\#$962; = fruit: fruit resembling that of Papaver species). All occur in South America, none having been found elsewhere so far. Although there is much doubt nowadays about the taxonomic significance of Fries{\textquoteright}s sections, we maintain sect. Mecocarpus at present for convenience{\textquoteright}s sake. Additionally, the former genus Guatteriopsis, united with Guatteria a short time ago (Erkens \&$\#$38; Maas 2008b), is now also included in sect. Mecocarpus. The same applies to one of the two species attributed to Guatteriella (also merged with Guatteria by Erkens \&$\#$38; Maas 2008b), namely Guatteriella tomentosa R.E.Fr. (not Guatteria tomentosa Rusby) which is put into synonymy with Guatteria trichocarpa Erkens \&$\#$38; Maas. One new species is described, namely Guatteria griseifolia Maas \&$\#$38; Westra. The two species complexes of G. guianensis and G. decurrens are now treated each as a single polymorphic species. The present study falls within the framework of a planned monograph of the whole genus Guatteria.}, keywords = {Annonaceae, Guatteria, GUATTERIA SECT.
