CD3A879CFF90FFB6FF77F896FA830EF8.taxon	distribution	Distribution: — Eugenia ruschiana is a tree from montane Atlantic rainforest of Espírito Santo state, occurring at altitudes from 250 to 790 m elev.	en	Bünger, Mariana De Oliveira, Mazine, Fiorella Fernanda, Stehmann, João Renato (2016): Eugenia ruschiana (Myrtaceae), a new species from southeastern Brazilian Atlantic forest.

CD3A879CFF90FFB6FF77F896FA830EF8.taxon	biology_ecology	Phenology: — Flowers were collected in August and October.	en	Bünger, Mariana De Oliveira, Mazine, Fiorella Fernanda, Stehmann, João Renato (2016): Eugenia ruschiana (Myrtaceae), a new species from southeastern Brazilian Atlantic forest.

CD3A879CFF90FFB6FF77F896FA830EF8.taxon	etymology	Etymology: — The specific epithet pays homage to Augusto Ruschi, who was an important ambientalist in Brazil, and it also refers to the locality were the species was collected, Augusto Ruschi Biological Reserve.	en	Bünger, Mariana De Oliveira, Mazine, Fiorella Fernanda, Stehmann, João Renato (2016): Eugenia ruschiana (Myrtaceae), a new species from southeastern Brazilian Atlantic forest. Phytotaxa 266 (1): 40-44, DOI: 10.11646/phytotaxa.266.1.6, URL: http://dx.doi.org/10.11646/phytotaxa.266.1.6
CD3A879CFF90FFB6FF77F896FA830EF8.taxon	conservation	Conservation status: — This new species is known from two collections from the neighboring municipalities of Santa Teresa and Santa Leopoldina (Figure 2), with populations of few individuals in an area with less than 5,000 km 2, since the two municipalities sum an area of 1,400 km 2 (IBGE 2016). Although the species also occurs in a protected area, forests around the type locality are very fragmented and show a continuing decline in extension, considering that only 18 % of the municipality of Santa Teresa retains its original vegetation (Mendes & Padovan 2000). According to the information mentioned before, Eugenia ruschiana is assessed here as Endangered (EN), fitting criteria B 1 ab (iii) of the IUCN Red List criteria (IUCN 2013), being criterion B 1 the extent of occurrence of less than 5,000 km ², criterion “ a ” the occurrence in less than five localities and “ b (iii) ” a continuing decline in the area and quality of the habitat.	en	Bünger, Mariana De Oliveira, Mazine, Fiorella Fernanda, Stehmann, João Renato (2016): Eugenia ruschiana (Myrtaceae), a new species from southeastern Brazilian Atlantic forest.

CD3A879CFF90FFB6FF77F896FA830EF8.taxon	discussion	Discussion: — The well developed bracteoles of Eugenia ruschiana place this species in Eugenia section Phyllocalyx (O. Berg) Niedenzu (Berg 1855 – 1856: 306, Niedenzu 1893: 82), a group proposed by Niedenzu to accommodate species previously segregated by Berg in his genus Phyllocalyx. Since the work of Niedenzu the merging of Phyllocalyx in Eugenia has been widely accepted, and the phylogenetic study of Mazine et al. (2014) showed section Phyllocalyx as a monophyletic clade embedded in Eugenia. Eugenia ruschiana is apparently related to E. itacarensis, an Atlantic rainforest species restricted to the southeastern state of Bahia, from which it can be distinguished through the characters cited in the following key:	en	Bünger, Mariana De Oliveira, Mazine, Fiorella Fernanda, Stehmann, João Renato (2016): Eugenia ruschiana (Myrtaceae), a new species from southeastern Brazilian Atlantic forest.
