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.

The closeness of these three genera was expressed by Fries when lie placed them in his (informal) Unonopsis group (Fries, 1959), and the close relationship is supported by more recent phylogenetic research as well. Four species are recognized in Bocageopsis and two species in Onychopetalum. Unonopsis is by far the largest of the three genera with close to 50 species, of which no less than 23 species are here described as new. One species (Unonopsis umbilicata) had to be shelved as insufficiently known for lack of data, and another, obviously new, species from Colombia is too incomplete and is described provisionally as Unonopsis spec. A. Several keys are provided, one for the genera and one each for the species of Bocageopsis and Onychopetalum. For the species of Unonopsis a key to all species and, in addition, a key to the species of Mexico and Central America are provided. The species treatments include full descriptions, geographical and ecological notes, distribution maps, synonymy, taxonomic notes, and vernacular names. A complete list of exsiccatae is appended. Parallel to the taxonomic revision, a leaf anatomical survey was made by E.-J. van Marle, and is included here.}, isbn = {0006-5196}, author = {Maas, P. J. M. and Westra, L. Y.
