89276377400B2A10589A2D0FC83B8360.taxon	distribution	Distribution and habitat: — Myrcia longisepala is endemic of Atlantic Forest and restricted to lowland coastal forests from Espírito Santo state in southeastern Brazil. The lowland forests of the Espírito Santo state are currently well studied by floristic surveys (Pereira & Araújo 2000, Assis et al. 2004, Rolim et al. 2016, Souza et al. 2016), including specific efforts for Myrtaceae (Giaretta & Peixoto 2015, Giaretta et al. 2016). These areas are one of the most Myrtaceae species-rich in Espírito Santo state and also important due to the endemism of Myrcia s. l. species (Murray-Smith et al. 2009, BFG 2015, Giaretta et al. 2015). Based on that, Myrcia longisepala is another example which highlights the species richness and high endemism of that area.	en	Amorim, Bruno S., Alves, Marccus (2018): New narrowly distributed species of Myrcia s. l.

8927637740082A16589A2863CCB58181.taxon	distribution	Distribution and habitat: — Myrcia rogersiana is endemic to Brazilian Atlantic Forest and restricted to the northern submontane forests of Espírito Santo state in southeastern Brazil. The southern portion of submontane forests of Espírito Santo state is known due to its high endemism of Myrcia s. l. and Gomidesia clade species (Sobral 2010 b, Amorim & Alves 2016), while the northern portion is historically poorly sampled (see Figure 1). The restrict distribution of Myrcia rogersiana highlights the importance of botanical efforts in poorly known areas and also the submontane and montane forests in Gomidesia clade species diversification (Amorim & Alves 2015, 2016, Amorim 2017).	en	Amorim, Bruno S., Alves, Marccus (2018): New narrowly distributed species of Myrcia s. l.
