5947EC78FFB2FFF71783FF37F26DFA88.taxon	distribution	Distribution and habitat: — Brazil (Bahia and Minas Gerais states) (Fig. 3). Both species of Maschalostachys are restricted to the northern portion of the Espinhaço Range of mountains in Bahia and Minas Gerais states. They are remarkably common treelets in a particular phytophysiognomy called caatinga rupestre. This vegetation occurs in transitional areas between the Cerrado and Caatinga domains and shows xeromorphic aspects, with numerous rocky outcrops, shallow soils and predominance of herbs and shrubs (rarely trees) up to 3 m tall, occurring at elevations of 750 to 1000 m high. Its floristic composition and lower elevations are major features distinguishing it from campos rupestres, the most widespread vegetation along the highlands of the Espinhaço Range (Campos et al. 2016).	en	Loeuille, Benoît, Roque, Nádia (2017): Maschalostachys, a new genus of Vernonieae (Asteraceae) from Brazil.

5947EC78FFB6FFF81783F937F312FEA2.taxon	discussion	Discussion: — Semir (1991) referred to a new undescribed species of Lychnophora, closely related to L. markgrafii, from Rio Pardo de Minas and named it “ L. mellosilvae ” but the author did not intend to publish this name at that time. The features that distinguish it from M. markgrafii are discussed under the latter species. Age-related variations in the habit have been noted: older individuals tend to form a larger woody trunk with pseudo-rosette of leaves and flowering branches towards the apex, whereas younger individuals display a poorly woody stem with the pseudo-rosette of leaves and flowering branches close to the base of the plant (Fig. 5 A, C and 6 B, D). Maschalostachys mellosilvae occurs in Espinhaço Range of mountains in northern Minas Gerais (Serra de Grão-Mogol and Serra Nova) and in southern Bahia (Serra Geral de Licínio de Almeida). It is sympatric with M. markgrafii in Serra de Grão Mogol and Serra Nova (Fig. 3). Populations from Serra Geral de Licínio de Almeida (Bahia) and from Minas Gerais show some morphological differences. Individuals from the Bahian population tend to have longer peduncles (up to 13.9 cm vs. 2.9 cm), a higher degree of fusion among heads (1 / 2 vs. 1 / 4 – 1 / 3 of its length), phyllaries densely villous (vs. poorly villous), a smaller number of florets per head (11 – 14 vs. 11 – 23) and rarely more ramified inflorescences. However, more field work is necessary to clearly understand how this morphological variation is spatially distributed, and at the moment it would be hasty to recognize this quantitative morphological variation at a taxonomic rank.	en	Loeuille, Benoît, Roque, Nádia (2017): Maschalostachys, a new genus of Vernonieae (Asteraceae) from Brazil.
