Passifloraceae na Serra Negra, Minas Gerais, Brasil

In this study are presented the species of Passifloraceae from Serra Negra, a part of Serra da Mantiqueira located in South Zona da Mata of Minas Gerais, in the coordinates 21º58'11"S and 43º53'21"W. The vegetation is represented by a mosaic of "campos rupestres" and semideciduous forests and rainforests. The family is represented by 12 species that belong to the genus Passiflora: P. alata Curtis, P. amethystina J.C.Mikan, P. campanulata Mast., P. capsularis L., P. edulis Sims, P. haematostigma Mart. ex Mast., P. marginata Mast., P. mediterranea Vell., P. porophylla Vell., P. sidifolia M.Roem., P. speciosa Gardner and a species not identified, probably a new taxon. To recognize the species, identification key to species, descriptions, illustrations, geographical distribution and taxonomical comments are provided.Neste trabalho são apresentadas as espécies de Passifloraceae da Serra Negra, parte da Serra da Mantiqueira localizada no sul da Zona da Mata de Minas Gerais, nas coordenadas 21º58'11"S e 43º53'21"W.

Lectotypes for species of Passifl ora L. (Passifl oraceae) described by João Barbosa Rodrigues

ABSTRACT During taxonomic review of the Brazilian species of the Passifl ora subgenus Astrophea and P. subg Decaloba, six names published by the Brazilian botanist João Barbosa Rodrigues were found in need of discussion: Passifl ora alliacea, P. amalocarpa, P. cabedelensis, P. hexagonocarpa, P. hydrophila and Tacsonia coccinea. Th e original illustrations are here designated as lectotypes for P. alliacea, P. amalocarpa, P. cabedelensis (a synonym of P. amalocarpa), P. hexagonocarpa, P. hydrophila (a synonym of P. costata) and Tacsonia coccinea (a synonym of P. spinosa)

New records of Passiflora from Itatiaia National Park, Brazil

We present new records of Passifloraceae sensu stricto from Itatiaia National Park, Brazil, contributing new data on the geographic distribution of four Passiflora L. species to the flora of Brazil: P. deidamioides Harms, P. miersii Mast., P. rhamnifolia Mast., and P. setulosa Killip. The last three species are reported from Itatiaia National Park and the last species from the state of Rio de Janeiro for the first time

Pollen morphology of selected species of Passiflora L. (Passifloraceae) from the Atlantic Forest

Pollen grains from twelve species of the Passifloraceae family from the Brazilian Atlantic Forest were analyzed: Passiflora subg. Astrophea (1sp.), P.subg. Decaloba (1sp.) and P.subg. Passiflora (10spp.). The current study aims to acquire additional information and feature the pollen morphology of the herein studied species to help setting a more precise taxa delimitation. Acetolyzed pollen grains were measured, described and illustrated using light and scanning electron microscopy. The pollen grains were medium or large sized, oblate spheroidal, suboblate, prolate spheroidal and subprolate; 4-colpate (P. kermesina), 6-12-pantocolporate (P. mediterranea), 6-colpate (P. mucronata), 6-colporate (P. pentagona), 12-colporate (P. misera) or 6-syncolpate (in most species). The presence of reticulate sexine, pseudopercula, pontopercula and/or opercula was observed. The endoaperture was just found in P. pentagonaand P. misera. It was concluded that pollen morphology is an important source of taxonomic features useful for distinguishing species and characterizing the three subgenera. The current study provides additional information that, along with other previously published studies, will enable a better understanding of phylogenetic relations among these strains
