1. Anatomical and histochemical characterization of Dipteryx odorata and Taralea oppositifolia, two native Amazonian species
Abstract Dipteryx odorata (Aubl.) Willd. and Taralea oppositifolia Aubl., Fabaceae: Dipterygeae, are two Amazonian species of great economic and pharmacological potential. The anatomy of these species, however, remains poorly studied. The aim of this work was to inventory leaf anatomical characteristics of D. odorata and T. oppositifolia and to locate and id

2. 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

3. Leaf histochemistry analysis of four medicinal species from Cerrado
ABSTRACT Chemical components act in plant defense and protection, but many of them are extracted and used medicinally. For Cerrado, active chemical components are used in the treatment of diseases, which strengthens the necessity for pharmacological studies of plants of that environment. The objective was to evaluate the histochemistry of the leaf blade of B

4. Pericarp ontogeny of Tapirira guianensis Aubl. (Anacardiaceae) reveals a secretory endocarp in young stage
ABSTRACT Most species of Anacardiaceae have drupes containing secretory structures.. The substances produced by these structures may have importance to industry and folk medicine, and may even cause allergenic effects. This work describes the ontogeny of pericarp of Tapirira guianensis with an emphasis on the secretory structures present at different stages

5. Anatomical and histochemical analysis of Dysphania ambrosioides supported by light and electron microscopy
ABSTRACT Dysphania ambrosioides (L.) Mosyakin & Clemants (syn: Chenopodium ambrosoides L.), Amaranthaceae, popularly known as “mastruz”, is an herb widely used in Brazil as anthelmintic. To contribute to the knowledge about medicinal plants, a microscopic analysis was accomplished to describe the main anatomical characters of root, stem, petiole and leaf

6. 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

7. Anatomy of vegetative organs of Scutellaria agrestis, a medicinal plant cultivated by riverine populations of the Brazilian Amazon
Scutellaria agrestis A. St. -Hil. ex Benth. , Lamiaceae (trevo-roxo) is cultivated for medicinal purposes by residents of the riverine communities in the State of Amazonas, Brazil. This study aimed to characterize the anatomy and to make histochemical analysis on vegetative organs of S. agrestis. Samples of the leaf, stem and root were collected from five pl

8. Anatomy and histochemistry of the vegetative organs of Cissus verticillata: a native medicinal plant of the Brazilian Amazon
The purpose of this paper was to carry out an anatomical and histochemical analysis of the vegetative organs of Cissus verticillata (L.) Nicolson & C.E. Jarvis, Vitaceae, to contribute for the attest the taxonomic identity of the medicinal plant. Samples from root, stem, leaf and tendril were cleared, dissociated and processed according to the usual methodol

9. Comparative anatomy of leaves of Kalanchoe pinnata and K. crenata in sun and shade conditions, as a support for their identification
Kalanchoe pinnata (Lam.) Pers. and K. crenata (Andrews) Haw., Crassulaceae, are popularly used in the treatment of many diseases. Their biological activities, such as anti-leishmaniasis and analgesic, can be useful in phytotherapy. Both species are often misidentified as the other, because of their similar popular uses and names, and the similar external mor

10. Morpho-anatomical analysis of Aspidosperma olivaceum and A. polyneuron, Apocynaceae
The family Apocynaceae includes many medicinal species, such as Aspidosperma olivaceum Müll. Arg. and A. polyneuron Müll. Arg. The first, popularly known as "peroba-branca", is a source of indole alkaloids that are recognized for their antitumor activity. The second, known as "peroba-rosa", is used by some people for treating malaria. To contribute to the

11. Leaf and calycine colleters in Odontadenia lutea (Apocynaceae - Apocynoideae - Odontadenieae): their structure and histochemistry
The structure and histochemistry of colleters found on the vegetative and floral apices of Odontadenia lutea are described. Colleters occur on vegetative apices starting at the fourth node, with 68 to 80 colleters being found at each node. Each leaf primordium has only one colleter of axillary origin, 3-5 intra-petiolar, and 12-16 inter-petiolar (intra-stipu

12. Centrolobium tomentosum: macro-and microscopic diagnosis of the leaf and stem
Centrolobium tomentosum Guillemin ex Benth., Fabaceae, known as "araribá-rosa", is a large tree that is widespread throughout Brazil. The bark of its stem is used in folk medicine as an astringent and the leaves are employed as a poultice for wounds and bruises. The aim of this study was to contribute to the pharmacognostic quality control of this medicinal
