“…Contudo, as folhas geralmente paripinadas, com um prolongamento da raque entre os folíolos terminais, a face abaxial dos folíolos geralmente com papilas vermelhas dispersas e a face adaxial geralmente recoberta por pequenas cavidades a semelhança de poros auxiliam no reconhecimento da espécie. Com relação as subespécies apresentadas por Pennington (1981) Fig. 2a-f Árvores 8-30 m de altura, gemas densamente pubescentes, ramos jovens pubescentes, amadurecendo glabros.…”

“…A distinção dessa espécie é realizada com base no ovário densamente pubescente com dois óvulos sobrepostos em cada lóculo. Na obra de Pennington (1981) Folli 6424, V. Demuner 2392). Além disso, a separação dos materiais com flores, muitas vezes é baseada em uma diferença menor que 1 mm de comprimento das estruturas (pétalas e anteras) e que mesmo assim é contínua com uma ou outra subespécie.…”

“…As informações sobre inflorescências são incompletas e desiguais. Considerou-se assim, que a divisão em subespécies para G. macrophylla, conforme apresentado por Pennington (1981), necessitam de maiores estudos. Penn., Revista Árvore 11:185.…”

“…Os principais trabalhos que trataram a família de modo amplo, são os de De Candolle (1824); Hooker (1862); C. De Candolle (1878a); Harms (1896Harms ( , 1940 e Pennington & Styles (1975). Também é importante ressaltar, os trabalhos de Pennington (1981) e Mabberley et al (1995) que trataram um grande número de espécies em regiões de importante diversidade para a família. Além disso, algumas revisões taxonômicas para os gêneros foram realizadas recentemente, como por exemplo, para a região neotropical, os gêneros Cedrela (Pennington & Muellner 2010), Carapa (Kenfack 2011), Guarea (Pennington & Clarkson 2013) e Trichilia (Pennington 2016) foram revistos nessa década.…”

ResumoMeliaceae possui 50 gêneros e cerca de 550 espécies distribuídas em todo mundo, embora com maior diversidade na região pantropical. No Brasil, são encontradas 84 espécies distribuídas em sete gêneros. Esse estudo apresenta o tratamento florístico das espécies de Meliaceae no estado do Espírito Santo. Para alcançar esses resultados, foram consultados os principais herbários do país, além de realizadas atividades de campo. Os principais resultados deste trabalho incluem, descrições morfológicas para os gêneros e as espécies, chaves de identificação, ilustrações e comentários taxonômicos. Com relação as novidades taxonômicas, foram encontradas 25 espécies que pertencem a quatro gêneros, uma pertencente a Cabralea, duas a Cedrela, seis a Guarea e 16 a Trichilia. Nesse estudo também são apresentados uma nova ocorrência para o estado e ainda, duas espécies de Trichilia são provisoriamente tratadas como Trichilia sp. 1 e Trichilia sp. 2. Palavras-chave: angiospermas, flora, Mata Atlântica, taxonomia. AbstractMeliaceae has 50 genera and about 550 species distributed in the whole world, although with greater diversity in the pantropical region. In Brazil, there are 84 species distributed in seven genera. This study presents the floristic treatment of the Meliaceae species in the state of Espírito Santo. In order to achieve these results, we consulted the main herbaria in the country and performed field activities. The main results of this work include the morphological descriptions of the genera and species, identification keys, illustrations and taxonomic comments. In terms of the taxonomic novelties, 25 species belonging to four genera were found: One belonging to Cabralea, two to Cedrela, six to Guarea, and 16 to Trichilia. In this study, we also present a new species occurrence for the state and therefore, the two Trichilia species are provisionally treated as Trichilia sp. 1 and Trichilia sp. 2.

According to the literature data on the chemical composition of the Trichilia genus performed in this work, it can be concluded that 334 different compounds were isolated and identified, distributed in monoterpenes, sesquiterpenes, diterpenes, triterpenes, steroids, limonoids, coumarins, flavonoids, lignans, phenolic acids, amino acids and lactones. Together with the structures of this compound, data from botanical classification and pharmacological results from extracts and pure compounds on the Trichilia genus were also described. The compounds derived from terpenes pathway were more significant, corresponding to about 87.7% of isolated and identified compounds from various Trichilia species. Among the different terpenoid skeletons of this kind, limonoids were meanly reported, appearing a total of 33.9% of compounds isolated from several Trichilia species.

Tree species distributions and local habitat variation in the Amazon: large forest plot in eastern Ecuador

et al. 2004

Summary 1We mapped and identified all trees ≥ 10 mm in diameter in 25 ha of lowland wet forest in Amazonian Ecuador, and found 1104 morphospecies among 152 353 individuals. The largest number of species was mid-sized canopy trees with maximum height 10-20 m and understorey treelets with maximum height of 5-10 m. 2 Several species of understorey treelets in the genera Matisia and Rinorea dominated the forest numerically, while important canopy species were Iriartea deltoidea and Eschweilera coriacea . 3 We examined how species partition local topographic variation into niches, and how much this partitioning contributes to forest diversity. Evidence in favour of topographic niche-partitioning was found: similarity in species composition between ridge and valley quadrats was lower than similarity between two valley (or two ridge) quadrats, and 25% of the species had large abundance differences between valley and ridge-top. On the other hand, 25% of the species were generalists, with similar abundance on both valley and ridges, and half the species had only moderate abundance differences between valley and ridge. 4 Topographic niche-partitioning was not finely grained. There were no more than three distinct vegetation zones: valley, mid-slope, and upper-ridge, and the latter two differed only slightly in species composition. 5 Similarity in species composition declined with distance even within a topographic habitat, to about the same degree as it declined between habitats. This suggests patchiness not related to topographic variation, and possibly due to dispersal limitation. 6 We conclude that partitioning of topographic niches does make a contribution to the α -diversity of Amazonian trees, but only a minor one. It provides no explanation for the co-occurrence of hundreds of topographic generalists, nor for the hundreds of species with similar life-form appearing on a single ridge-top.
