1. Comparative vegetative anatomy of Neotropical Goodyerinae Klotzsch (Orchidaceae Juss.: Orchidoideae Lindl.)
ABSTRACT The Neotropical genera Aspidogyne and Microchilus (Goodyerinae, Cranichideae, Orchidaceae) comprise ca. 200 rainforests terrestrial species. Although species of Goodyerinae are described with similar anatomy to other taxa of Cranichideae, some anatomical characteristics appear to be specific to the subtribe. Our goal was to characterise the anatomic

2. Licófitas e samambaias do Parque Estadual Monte Alegre (PEMA), Pará, Brasil
RESUMO O Cerrado é um importante domínio fitogeográfico brasileiro, uma vez que abrange porcentagem considerável do território nacional. Nesse domínio há estimativas de 241 a 284 espécies de samambaias e licófitas, apesar disso, há poucos trabalhos ressaltando-as nesse ambiente, assim o objetivo desse estudo foi realizar um levantamento das plantas

3. Pouteria (Sapotaceae) na Estação Biológica de Santa Lúcia, ES, Brasil
Resumo Sapotaceae (Ericales) é uma família pantropical com 58 gêneros e cerca de 1.250 espécies sendo Pouteria o gênero mais rico com aproximadamente 200 espécies. No Brasil são registradas 124 espécies, das quais 52 são endêmicas. Na Floresta Atlântica são citadas 40, das quais a maioria pode ser encontrada nos estados do Espírito Santo e Bahia

4. Chave de identificação dendrológica das espécies mais comuns de uma área de Cerrado sensu stricto, Gurupi, Tocantins
Resumo Estudos com chave de identificação dendrológica da flora arbustivo-arbórea do Cerrado no Estado do Tocantins ainda são escassos ou incipientes, promovendo, assim, uma lacuna de informações técnicas e científicas. Portanto, esta pesquisa visa respaldar o estabelecimento de prioridades para futuras estratégias de conservação e planos de mane

5. Genetic parameters in agronomic characters for selection of superior lineages of Ricinus communis L
RESUMO: O conhecimento da variabilidade e herdabilidade dos caracteres agronômicos de interesse auxiliam na seleção de materiais superiores. Desta forma, objetivou-se avaliar os parâmetros genéticos de caracteres agronômicos em linhagens de mamoneira e quantificar as correlações genéticas entre eles. O trabalho foi desenvolvido na área experimental

6. Fruit of Lepidaploa (Cass.) Cass. (Vernonieae, Asteraceae): anatomy and taxonomic implications
ABSTRACT Lepidaploa is a taxonomically complex genus of Vernonieae, which is difficult to delimit morphologically due to vegetative and reproductive characters that overlap with Chrysolaena and Lessingianthus. Anatomical studies of cypselae are taxonomically useful for delimiting subtribes, genera and species of Asteraceae, and especially within Astereae and

7. Phenodynamics of five orchids species growing on rock outcrops in the Chapada Diamantina Mountains in northeastern Brazil
ABSTRACT We evaluated the vegetative and reproductive phenological patterns of the orchids Cattleya elongata, Cyrtopodium aliciae, Epidendrum orchidiflorum, Epistephium lucidum, and Sobralia liliastrum (Orchidaceae) growing on sandstone outcrops in the Chapada Diamantina Mountains in northeastern Brazil. Phenological events were associated with abiotic facto

8. A study of the morphoanatomical characters of the leaves of Chamaecrista (L.) Moench sect. Apoucouita (Leguminosae-Caesalpinioideae)
ABSTRACT Little attention has been paid to species of Chamaecrista sect. Apoucouita (Leguminosae-Caesalpinioideae), especially regarding anatomical studies. When only vegetative material is available, the identification of such species may be difficult. Additionally, vegetative material of some species of C. sect. Apoucouita may be even harder to identify be

9. Ontogeny, allometry and architecture of Psychotria tenuinervis (Rubiaceae)
We evaluated the ontogeny of the understory shrub Psychotria tenuinervis Müll.Arg., considering morphological and morphometric characters. Four ontogenetic stages were identified: seedling, juvenile, immature and adult (vegetative and reproductive phases). Size measurements and allometric relationships of the stem and crown were compared between the immatur

10. Chemical and pharmacognostical characterization of two Malaysian plants both known as Ajisamat
Ajisamat, an herb commonly used as an aphrodisiac in the Malaysian traditional medicine, corresponds to two different species from different families - Salacia macrophylla Blume, Celastraceae, and Prismatomeris glabra (Korth.) Valeton, Rubiaceae. Macromorphological inspection of the vegetative parts both plants reveals only a slight difference in the arrange

11. Three new species of Sloanea L. (Elaeocarpaceae) from the Central Amazon, Brazil
Three new species of Sloanea L. are recognized based on specimens collected in the Adolpho Ducke Forest Reserve. These new species are morphologically distinct from other Sloanea in the Neotropics in terms of their vegetative and reproductive characters. The Ducke Reserve contains a total of 18 species of Sloanea, and the species closest to these new taxa oc

12. Lecythidaceae Poit. in the Tupé Sustainable Development Reserve, Manaus, Brazil
Lecythidaceae is the family of the Brazil nut, and comprises about 300 species belonging to 17 genera with pantropical distributions. One hundred and twenty-two species belonging to nine genera are distributed throughout Brazil, demonstrating its greatest diversity in the Amazon rainforest where Lecythidaceae is also one of the most abundant families. It is
