Macrolobium paulobocae is presented as a new species of the legume subfamily Detarioideae. It is restricted to seasonally flooded igapó forests in the Central Amazon. We provide a description, illustration, photographs, and a distribution map of the new species, as well as a table of comparative morphology with similar, likely phylogenetically rela...
The genus Scaphyglottis Poepp. & Endl. presents 78 species and occurs from Mexico to Brazil. Scaphyglottis punctulata (Rchb.f.) C.Schweinf. is known from various high elevation locations from Panama to Bolivia. Here, we report new records in two regions of the Brazil portion of the Guiana Shield. We provide a detailed description, photographic plat...
The association of the ant Myrcidris epicharis with the plant Myrcia magna is reported for the first time. This association was registered in two localities along the Negro river basin, in the region of Manaus, Amazonas state, Brazil. The ants inhabit swollen shoots in apical and subjacent nodes of the branches. This record represents the second pl...
We present the amended description of the species Acmanthera minima and A. parviflora based on specimens collected in the Lower Negro River basin and the Serra do Aracá National Park, respectively, in the Amazonas State, Brazil. We also provide photographs, a distribution map, notes on conservation status and a key to all species of the genus Acman...
The new species Myrcia psammophila is here described, illustrated and compared with M. grandis and M. umbraticola, two morphologically similar taxa. It may be distinguished from these two latter species based on possession of leaves with corky petiole and raised midvein adaxially, and distinctly pedicellate flowers with squared staminal ring and se...
Schoepfia clarkii is a rare species of Schoepfiaceae that to date has been known only from the single flowering specimen used in the original description from white-sand vegetation in Venezuela. Here we report new records for this species collected from the lower Negro River basin in Brazil, ca. 900 km from the type locality, but also from white-sa...
Macrolobium aracaense (Fabaceae), a new endemic treelet species from Brazil, is here described and illustrated. Morphologically it is similar to M. longipes: both are treelets, the leaflets have the same shape and are covered by papillary epidermis on the abaxial surface, and the sepals apex are minutely ciliate. Macrolobium aracaense occurs in sym...
