Six Eugenia species from the Atlantic Forest of Alagoas state, northeastern Brazil, are described here: Eugenia anthropophaga, E. cambemba, E. curuba, E. jussara, E. mammifera, and E. palmarina. Eugenia anthropophaga and E. jussara are morphologically similar to each other but distinguished by the ovate (vs. linear in E. jussara) bracts, fruiting pedicels not swollen (vs. swollen) at the base, and subglobose (vs. pyriform), pilose (vs. glabrescent) and deeply 8-costate (vs. slightly 8-costate) fruits with patent (vs. erect) calyx lobes. Eugenia cambemba is morphologically similar to E. valsuganana but differs by the leaf blades cuspidate at the apex, and fruits longer, obovoid, and reddish when ripe. Eugenia curuba is similar to E. pruinosa, differing by the leaf blades obtuse to rounded at the apex, with 12–14 secondary veins per side, and sessile fruits with subtly glandular-rugose surface. Eugenia mammifera differs from E. coffeifolia by the elliptic leaf blades with 14–17 secondary veins, eciliate calyx lobes, and fruits 8-costate and constricted at apex. Eugenia palmarina differs from E. barrana by the widely elliptic leaf blades with minute glandular dots on the adaxial surface, with 12–15 secondary veins per side, and longer triangular or linear bracts. Due to the restricted distribution and imminent threats, the new species are provisionally considered as Critically Endangered (CR), in accordance with the IUCN criteria. Data about geographical distribution, habitat, and comments on morphological affinities are provided.

Five new species of Ruellia from the Atlantic Forest of northeastern Brazil are described: Ruellia curupira, R. fulozinha, R. insurrecta, R. jiboia, and R. taboleirana. Ruellia curupira (from the States of Alagoas and Bahia), R. fulozinha (Alagoas and Pernambuco), R. insurrecta (Alagoas), and R. jiboia (Alagoas and Bahia) occur exclusively in forested areas, whereas R. taboleirana is restricted to “Tabuleiros litorâneos” (Tabuleiro savanna) vegetation from Rio Grande do Norte to Alagoas. Due to the restricted distribution, resulting from high fragmented areas and the imminent threats, the five new species here proposed are provisionally considered under some degree of threat in accordance with the IUCN criteria. We provide morphological descriptions, comments on morphological affinities, data on habitat and distribution, as well as illustrations and photographs of living plants.

Abstract—Three new species of Eriocaulaceae, endemic to the Serra da Canastra in Minas Gerais state, are described. Paepalanthus petraeus is assigned to P. ser. Paepalanthus, differing within the series by its thickened stem accumulating leaf sheaths, linear leaves, and numerous scapes shorter or equaling the leaf height and bearing capitula with brown involucral bracts. Paepalanthus sinuosus belongs to P. subsect. Polyactis and is distinguished by few scapes in lax fascicles, more than twice as long as the leaves, which are patent to slightly recurved, and light brown involucral bracts with acute apex. Syngonanthus culcitosus, within S. sect. Syngonanthus, is unique due to its elongate and branched stem forming dense mats, simple inflorescences, cream-colored involucral bracts equaling the length of the floral disc, and gynoecium with nectariferous appendages. Comparisons with the most similar species are provided for each new taxon. Maps, photographs, and illustrations are presented, together with comments on phenology, distribution, habitat, and morphology. Paepalanthus petraeus and P. sinuosus are likely to be assessed as Critically Endangered, and S. culcitosus as Vulnerable, according to IUCN criteria.

Eulaema (Apeulaema) felipei sp. n., a species extremely similar to the Amazonian Eulaema (Apeulaema) mocsaryi (Friese, 1899), is described from Murici (state of Alagoas, northeastern Brazil). This species seems to be restricted to a single patch of Atlantic Forest at the ‘Estação Ecológica de Murici’. Although this preserve is supposedly protected by law, the small area (less than 3,000 ha) where this bee occurs is entirely surrounded by pastures and sugar cane plantations, and anthropic pressure is strikingly high in the region. Several other endemic animal and plant species are known from the same area. Eulaema felipei sp. n. is considered as Critically Endangered according to IUCN criteria. An updated identification key for all the species of Eulaema (Apeulaema) Moure, 1950 is also provided.

Paepalanthus mellosilvae is here described and illustrated as a new species of Eriocaulaceae from the Atlantic Forest domain in Minas Gerais state, Brazil. The new species is known from a single locality in the Mantiqueira Range, growing along trails through cloud forests. According to the IUCN criteria, it is suggested here as critically endangered. Paepalanthus mellosilvae is compared to P. harmsii, a morphologically similar species also growing in the Mantiqueira Range, being mainly distinguished by the presence of a rhizome, narrower leaves, more numerous scapes, narrower capitula, sparsely pilose involucral bracts, and obdeltate floral bracts. Additional comments on the taxonomy, morphology, and distribution of the species, along with illustrations are provided. The specific epithet is a tribute to Prof. Dr. Renato de Mello-Silva.

Three New Species

Three species of Graphidaceae are here described as new to science, based on material found in the Reserva Biológica Guaribas and Área de Proteção Ambiental da Barra do Rio Mamanguape, in Paraíba State, Northeastern Brazil. Astrochapsa submuralis E.L. Lima, Lücking & M. Cáceres, with thickly pruinose ascomata and small submuriform ascospores, Chapsa angustispora E.L. Lima, Lücking & M. Cáceres, with a combination of inspersed hymenium and comparatively narrow muriform ascospores, and Graphis cilindrospora E.L. Lima, Lücking & M. Cáceres, with very large and narrow muriform, brownish ascospores. These findings underline the importance of the northern Atlantic rain forest, including the poorly studied Restinga vegetation, for the continuous discovery of new lichen taxa.
