25. Anatomical characters and chemical profile of leaves of three species in Lauraceae family
ABSTRACT The Lauraceae family is widely distributed in tropical and subtropical climates, has more than 2500 species and in the taxonomic point of view, it is one of the most difficult families to identify species. The aim of this study was to analyze the leaf anatomy of three species of Lauraceae (Ocotea indecora (Schott) Mez, Nectandra barbellata Coe-Teix.

26. Leaf anatomy of Protium ovatum and its antiproliferative potential in cervical cells
ABSTRACT The aim of this study was to analyze the morphology and anatomy of the leaves of Protium ovatum Engl., Burseraceae, and verify the antiproliferative activity in cervical cells. For anatomical analysis, the leaf samples were fixed in formol, acetic acid, alcohol 70, dehydrated, included in hydroxyethyl methacrylate and sectioned at a thickness of 5�

27. Structural features of species of Asteraceae that arouse discussions about adaptation to seasonally dry environments of the Neotropics
ABSTRACT Seasonally-dry environments of the Neotropics, such as the South American Chaco, exert selective pressures on vegetation through a pronounced water deficit. We describe the underground system and leaf anatomy of three species of Asteraceae from the Brazilian portion of the Chaco (Pterocaulon purpurascens Malme, Wedelia trichostephia DC., and Pectis

28. Leaf glands of Banisteriopsis muricata (Malpighiaceae): distribution, secretion composition, anatomy and relationship to visitors
ABSTRACT Leaf glands are common structures in Malpighiaceae and exhibit great morphological diversity, yet information on their anatomy, secretion and type of visitors remains scarce. The aim of this study was to describe the distribution, anatomical development and chemical and functional properties of leaf glands of Banisteriopsis muricata (Malpighiaceae).

30. Pharmacobotanical study of Hypericum thymopsis
ABSTRACT Hypericum thymopsis Boiss., Hypericaceae, is an endemic herb which generally grows at the calcareous steppe regions of Central Turkey. In flowering stage, the aerial parts of this species are used for wound-healing and sedation, and its infusions are used against stomach diseases and throat infections by local people. The aim of this study, to exami

31. Secretory spaces in species of the clade Dipterygeae (Leguminosae, Papilionoideae)
ABSTRACT Dipteryx, Pterodon and Taralea are legume genera known for secreting oils, produced in secretory canals and cavities, with medicinal properties. We analyzed the distribution, morphology and histochemistry of these glands in leaves and stems of Dipteryx alata, Pterodon pubescens and Taralea oppositifolia, three Neotropical species, using standard tec

32. The structural studies on the medicinal plant Haplophyllum telephioides
ABSTRACT Haplophyllum telephioides Boiss., Rutaceae, is an endemic herb which generally grows at the steppe region in Central Turkey. Its aerial parts in flowering stage are used by local people against influenza virus due to its antimicrobial effect. The main purpose of this study was to examine the morphology, anatomy and histology of the vegetative and re

33. Yes, they can! Three-banded armadillos Tolypeutes sp. (Cingulata: Dasypodidae) dig their own burrows
ABSTRACT It is believed that the two species of Tolypeutes Illiger, 1811are the only armadillos that do not dig their own burrows, and that these species simply re-use burrows dug by other species. Here, we show that Tolypeutes matacus (Desmarest, 1804) and Tolypeutes tricinctus (Linnaeus, 1758) dig their own burrows. We describe the burrows and three other

34. Comparative study on morpho-anatomy of leaf, stem and root of Boerhaavia diffusa L. (Nyctaginaceae) and its adulterant plants
ABSTRACT Punarnava (Boerhaavia diffusa L.- Nyctaginaceae) is a promising drug to rejuvenate new cells in the body. It is well known in Ayurvedic medicine and locally called Tambadivasu. Superficially it is similar to other species of Boerhaavia and species of Trianthema and Sesuvium. Due to the minute morphological differences, the above plants are erroneous

36. Comparative anatomy of calyx and foliar glands of Banisteriopsis C. B. Rob. (Malpighiaceae)
Banisteriopsis is considered one of the largest genera of Malpighiaceae with 58 species, of which 47 occur in Brazil. The typical calyx and leaf glands of Banisteriopsis are considered relevant to the adaptive success of Malpighiaceae. Comparative studies of anatomical and histochemical characteristics may reveal similarities and assist in the interpretation
