3. Leaf morphology and venation of Psidium species from the Brazilian Savanna
ABSTRACT The Brazilian Savanna biome has the largest plant diversity among savannas worldwide and is the predominant biome in Goiás state, Brazil. Among plant species previously catalogued in the Brazilian Savanna, the Myrtaceae family has received attention, as these plants show great economic potential for its medicinal properties, food and ecological imp

4. Leaf venation pattern to recognize austral South American medicinal species of "cow's hoof" (Bauhinia L., Fabaceae)
ABSTRACT The leaves extracts of some species of Bauhinia L. s.l. are consumed to treat diabetes, inflammation, pains and several disorders in traditional medicine in austral South America. Despite its wide use and commercialization, sale is not controlled, and botanical quality of samples is not always adequate because of plant misidentification and adultera

6. Comparative study of three Marantodes pumilum varieties by microscopy, spectroscopy and chromatography
Abstract Marantodes pumilum (Blume) Kuntze (synonym: Labisia pumila (Blume) Fern.-Vill), Primulaceae, is well known for its traditional use as a post-partum medication among women in Malaysia. Three varieties of M. pumilum, var. alata Scheff., var. pumila and var. lanceolata (Scheff.) Mez. are commonly used. Nowadays, M. pumilum powder or extracts are commer

7. Comparative leaf anatomy and morphology of some Brazilian species of Crotalaria L. (Leguminosae: Papilionoideae: Crotalarieae)
Anatomical characters often provide strong taxonomic evidence and many times help define species whose morphological limits are in question. This study aimed to survey characters of the leaf anatomy of 16 species of Crotalaria L. occurring mostly in the cerrado (savanna) of central Brazil and in areas of restinga (coastal woodland, or sandy forest) along the

8. Anatomia foliar de espécies de Aspleniaceae e Polypodiaceae (Monilófitas) ocorrentes no Parque Estadual da Serra do Brigadeiro, MG, Brasil / Leaf anatomy of Aspleniaceae and Polypodiaceae (Monilophytes) species occurring in the Parque Estadual da Serra do Brigadeiro, MG, Brazil
Pteridophyta is a term used to denominate vascular plants lacking seeds that are dispersed by spores, with a life cycle characterized by two distinct phases: a gametophytic and a sporophytic phase. There are approximately12, 240 fern species displaying great diversity in wet tropical regions. In Brazil, 1,200 to 1,300 species are estimated to exist, with at

9. Padrão de venação e epiderme foliar de espécies de lauraceae juss do Distrito Federal, Brasil
Eighteen Lauraceae species, occurrent in Distrito Federal Brazil, had their leaf blades examined with the aim to assess the general characters usually considered in studies about epidermis and leaf architecture beyond proposing the use of additional characters. For the venation patterns analysis, some characters were proposed as well as the distancing betwee

10. Description and mapping of morpho-anatomical characters from leaves of Pilocarpus Vahl (Rutaceae) and related genera / Descrição e mapeamento de caracteres norfo-anatômicos foliares em Pilocarpus Vahl (Rutaceae) e gêneros relacionados
A maioria dos estudos filogenéticos envolvendo Rutaceae foi baseada em dados macromoleculares e poucos utilizaram gêneros neotropicais. Uma exceção a esses trabalhos, foi a análise filogenética de Pilocarpus, um gênero de Rutaceae neotropical, baseada em caracteres morfológicos proposta por Dias e colaboradores. Considerando a importância dos estudo

11. Plant species identification based on venation system shape analysis / "Identificação de espécies vegetais através da análise da forma interna de órgãos foliares"
The plant species diversity makes their correct identification a very complex task. The traditional taxonomy models, associated with species biodiversity, has been transformed this task in a challenger for the researches. This work presents a new approach to plant species identification, based on internal characteristics of leaf form. The data are collected

12. Estudos taxonomico, micro-morfologico e filogenetico do genero Himatanthus Willd. ex Schult. (Apocynaceae: Rauvolfioideae - Plumerieae)
t: A new circunscription and delimitation of Himatanthus Willd. ex Schult. based on taxonomic, micro-morphological and phylogenetic studies are proposed here. Nine species distributed in the Neotropics were recognized, among them, six species in the Amazonian region: H attenuatus (Benth.) Woodson, H phagedaenicus (Mart.) Woodson, H revolutus (Huber) Spina &K
