First records of Tovomita stergiosii Cuello (Clusiaceae: Clusieae) in Brazil

New records of Tovomita stergiosii Cuello, a species previously recorded for Peruvian and Venezuelan Amazon, are presented for Brazil. We present a distribution map, as well as comments and illustrations on taxonomic related species. DOI: 10.15560/10.6.1570 Figure 1. Floral buds of staminate flower of Tovomita species. A.

range in those characters throughout populations in the Amazon and Atlantic Forests.However, the shape of floral buds on staminate flowers is crucial for identifying it.This species is also morphologically related to T. glazioviana Engl.(Figure 1B) and T. stylosa Hemsl.(Figure 1D), and their morphological differences are presented on Table 1.
Tovomita stergiosii was only previously cited for the western portion of Imeri and Madeira provinces (Cuello 2003;Morrone 2014) in the territories of Venezuela and Peru, respectively.These provinces are remarkably known for showing high rates of endemism for different taxa, representing different biogeographic units in the Neotropics (Morrone 2014).Our data represent a wider Clusiaceae Lindl.comprises 14 genera and about 600 species predominantly distributed in the tropics worldwide (Stevens 2014).The family is currently divided into three tribes: Garcinieae Choisy, Symphoineae Choisy, and Clusieae Choisy, the later including Clusia L., Chrysochlamys Poepp., Dystovomita (Engl.)D ' Arcy, Tovomita Aubl., and Tovomitopsis Planch. & Triana (Ruhfel et al. 2013).
Tovomita is represented by ca.45 species (Cuello 2003) distributed throughout Neotropical rainforests, which 30 of them are found within the Brazilian Amazon and Atlantic Forests (Bittrich et al. 2014).The genus is characterized by dioecious trees and shrubs, in which pistillate specimens show smaller and fewer flowers than staminate specimens.Leaves are gathered on short branches, yellowish latex is common (Gentry 1997), inflorescences are cymose, terminal, and fruits are fleshy capsules (Cuello 2003).

Tovomita stergiosii
Tovomita stergiosii is easily recognized by its white latex, lanceolate to linear leaves, pedicel elongated, floral buds ovate and mucronulate at apex in staminate flowers, not mucronulate in pistillate flowers, stamens of staminate flowers and staminodes of pistillate flowers reduced in number to 20 (Cuello 2003).
