| Large elongated glands occur on Cercideae leaf surfaces. Leaves of Bauhinia (55 taxa, 53 species), Cercis (1 species), Phanera (1 species), Piliostigma (2 species), Schnella (19 species) and Tylosema (1 species) were observed to determine location and relative number of glands. They were only observed on the abaxial leaf surface of 42 Bauhinia taxa. The glands were analyzed by light stereomicroscope and scanning electron microscopy. They are large (up to 270 µm long and 115 µm wide) and multicellular, containing lipophilic substances, probably volatile oils. Presence or absence and density of the glands in species of Bauhinia may be useful to determine species delimitation or distinction among infraspecific taxa. Higher density of glands is more common in... |

| The Atlantic Forest on the slopes of Serra do Mar around Cubatão (São Paulo, Brazil) has been affected by massive emissions of pollutants from the local growing industrial complex. The effects of air pollution on the amounts of leaf nitrogen, total soluble phenols and total tannins of Tibouchina pulchra Cogn., a common species in the area of Cubatão, were investigated, as well as the possible influence of the altered parameters on the leaf area damaged by herbivores. Fully expanded leaves were collected at two sites: the valley of Pilões river (VP), characterized by a vegetation virtually not affected by air pollution and taken as a reference; and valley of Mogi river (VM), close to the core region of the industrial complex, and severely affected by air... |

| Áreas verdes, ruas e praças arborizadas em locais urbanos são características que apenas recentemente adquiriram relevância no mundo ocidental. Parece que os habitantes antigos das cidades não valorizavam uma estreita proximidade com plantas. Neste artigo, sugere-se que isso é uma conseqüência de uma ruptura entre o homem e a natureza, que ocorreu na emergência da tradição judaico-cristã na história da civilização ocidental. A ausência de laços entre natureza e cristianismo é evidente na ausência de árvores, jardins e outros aspectos representativos da natureza em torno de templos cristãos. O cristianismo também representou o fim da mitologia, um processo que conduziu ao desenvolvimento do pensamento racional, favorecendo assim o desenvolvimento da... |

| The seeds of 14 species from the caatinga, a dry forest ecosystem of the semiarid region of northeast Brazil, were analysed for total protein and total lipid contents, as well as fatty acid distribution. The seeds of Argemone mexicana L., an introduced and naturalized species in Brazil, commonly found in caatingas and other vegetation, were also analysed. The protein contents ranged from 123 g.kg-1 to 551 g.kg-1, higher contents being found in species of Leguminosae, but also in Jatropha mollissima (Pohl) Baill. (Euphorbiaceae, 409 g.kg-1). Oil contents ranged from 10 g.kg-1 to 400 g.kg-1. The contents of protein and oil were found to be inversely proportional in the seeds of most species, the figures for proteins being generally higher than those of... |
