| The yellow passion Passiflora edulis f. flavicarpa Deg. is allogamous, self incompatible, and it depends of insects pollinators to disseminate the pollen grains. The field work was conducted at Campos dos Goytacazes, Rio de Janeiro, Brazil, from October 17 to November 9 and December 12 to 21, 1995. It was analyzed 1565 flower buds, from which 423 showed well developed ovaries, five days after opening, this represents 27% of fruit set by natural pollination. It was observed 76,86 % of completely curved flowers, 21,22 % of partially curved flowers, and 1,92 % flowers without curvature. Five species of bees where observed on the flowers, from which two were the effective pollinator of yellow passion flower: Xylocopa (Megaxylocopa) frontalis (Olivier, 1789)... |

| Two species of Leandra that occur in the Atlantic Forest, in the state of Espírito Santo, eastern Brazil, are described and illustrated here. Leandra cristata has been found in the understory of montane rain forest, and can be recognized by the distinct nodal ridges on the young branches, by the leaves with decurrent bases and transversal nerves consistently perpendicular to the main nerve, by the triangular external teeth, and by the dorsal bump on the stamen connective. Leandra fontanae has been found in shrubby vegetation on inselbergs, and can be recognized by the small and cordate leaves with five main nerves plus a faint submarginal pair, by the apical and lateral inflorescences made up by single dichasia or a triad, by the flowers mostly 4-merous... |

| Pseudolaelia is a genus endemic to eastern Brazil. The species are often epiphytes on Velloziaceae or are saxicolous, predominantly on granitic and gneissic outcrops (inselbergs) in the Atlantic Forest and, less often, in the campos rupestres (dry, rocky grasslands) of the cerrado (savanna) and caatinga (shrublands). The genus is characterized by homoblastic pseudobulbs, long rhizomes, long and usually slender inflorescences, racemes or panicles, bearing pink, yellow or whitish flowers, labellum often 3-lobed, with simple, fimbriate or erose margin, semi-cylindrical or claviform column, cuniculus present. Twelve species are recognized; seven binomials are placed in synonymy. Of those seven, three are considered illegitimate because, contrary to the... |
