Seed micromorphology and its taxonomic significance to Xyris (Xyridaceae, Poales)
(2016-06-01)
The seed micromorphology was studied in eight species of Xyris (Xyridaceae) with taxonomic purposes. The results show that the presence of longitudinal endotegmic ridges in the seed coat is a pattern for the genus and that ...
MORPHOLOGY, MINERALOGY AND MICROMORPHOLOGY OF SOILS ASSOCIATED TO SUMMIT DEPRESSIONS OF THE NORTHEASTERN BRAZILIAN COASTAL PLAINS
(UNIV FEDERAL LAVRAS-UFLALAVRAS, 2012)
The scarcity of comprehensive characterizations of soils associated to gentle summit depressions of the Northeastern Brazilian Coastal Plains justifies this work, which had as objective to provide basic information for the ...
Micromorphology and anatomy of the leaf blade: a contribution to the taxonomy of Luziola (Poaceae, Oryzoideae) from the Pantanal, Brazil
(Springer, 2016-03-01)
Luziola comprises nine monoecious, aquatic species and has its center of diversity in South America. Due to the morphological similarities among Luziola species in the vegetative stage, the micromorphology and anatomy of ...
The contribution of foliar micromorphology and anatomy to the circumscription of species within the Chusquea ramosissima informal group (Poaceae, Bambusoideae, Bambuseae)
(Springer, 2017-06-01)
Chusquea is a diverse but monophyletic genus of Neotropical woody bamboos from primarily montane forests that comprises four well-supported lineages: subg. Magnifoliae, subg. Platonia, subg. Rettbergia, and the Euchusquea ...
Comparative scanning electron microscopic study of the effect of different dental conditioners on dentin micromorphology
(2008-01-01)
This study evaluated comparatively by scanning electron microscopy (SEM) the effect of different dental conditioners on dentin micromorphology, when used according to the same protocol. Forty dentin sticks were obtained ...

This study evaluated comparatively by scanning electron microscopy (SEM) the effect of different dental conditioners on dentin micromorphology, when used according to the same protocol. Forty dentin sticks were obtained ...
Floral ultrastructure of two Brazilian aquatic-epiphytic bladderworts: Utricularia cornigera Studnička and U. nelumbifolia Gardner (Lentibulariaceae)
(2017-01-01)
Utricularia cornigera and Utricularia nelumbifolia are giant, aquatic-epiphytic species of carnivorous bladderwort from southeastern Brazil that grow in the central ‘urns’ of bromeliads. Both species have large, colourful ...
Lapa das boleiras rockshelter: stratigraphy and formation processes at a paleoamerican site in Central Brazil
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2008)
Lapa clas Boleiras rockshelter, a Paleoamerican archaeological site in Central Brazil, was intensely occupied by humans from 10,000 C-14 BP (11.8 cal kyr BP), until approximately 7500 C-14 BP (8.4 cal kyr BP). In this paper ...
Soil Structure Under Irrigated Beans And Different Soil Management Practices
(SOC BRASILEIRA DE CIENCIA DO SOLOVICOSA, 2015)
A scanning electron microscopy study of the seed and post-seminal development in Angelonia salicariifolia Bonpl. (Scrophulariaceae)
(Academic Press Ltd, 2001-09-01)
The external morphology of seeds and post-germination developmental stages of Angelonia salicariifolia Bonpl. (Scrophulariaceae) were investigated using scanning electron microscopy. Some structural features of the seed ...
