En este trabajo se caracterizo el indumento observado en diferentes organos de 9 especies de Loasaceae presentes en Venezuela, precisando su ubicacion en la planta a fin de establecer una posible importancia taxonomica. Este estudio se efectuo tanto al microscopio optico como al microscopio electronico de barrido. El indumento esta constituido por 2 clases de apendices epidermicos: tricomas y emergencias. Los tricomas se clasificaron en tricomas eglandulares uni y multicelulares y tricomas… 
Estruturas secretoras florais em espécies de Leguminosae = Floral secretory structures in species of Leguminosae
Apesar de a familia Leguminosae ser rica em especies, exibir ampla distribuicao geografica e grande variacao morfologica, seus representantes tem sido pouco estudados em termos de estruturas
Ontogeny resolves gland classification in two caesalpinoid legumes
Robust glandular appendages are reported in legumes of the Caesalpinieae tribe. Most studies only attempt to describe the external morphology of these structures, without providing a distinction
Stinging Trichomes in Apocynaceae and Their Evolution in Angiosperms
Stinging trichomes are rare in plants, occurring only in angiosperms, where they are reported for a few genera belonging to six families. Although there is no report of stinging trichomes in


Floral ontogeny and morphology of Cevallia, Fuertesia, and Gronovia (Loasaceae Subfamily Gronovioideae)
Members of Loasaceae subfamily Gronovioideae have distinctive flowers compared to those of other members of the family, and share with their sister group Mentzelia the loss of a petal‐stamen synorganization that is present in other investigated members ofLoasaceae.
Phylogenetic relationships of Loasaceae subfamily Gronovioideae inferred from matK and ITS sequence data.
Phylogenetic analyses based on sequences of the chloroplast gene matK and the internal transcribed spacer region of nuclear rDNA have been conducted using parsimony and maximum likelihood methods to assess the monophyly of Gronovioideae and to determine the sister group relationships of gronovioid genera.
Abstract South American taxa of Mentzelia L. (Loasaceae) are revised and morphologically and ecologically characterized on the basis of extensive field studies, cultivation of several taxa, and a
Seed Morphology of Eucnide and Other Loasaceae
Seed morphology has proven to be a valuable feature in many systematic studies, particularly with the application of scanning electron mi- croscopy (SEM) and two investigations indicate that seeds may provide valuable characters for elucidating macroevo- lutionary relationships among Loasaceae.

Families Treated in This Volume are described in more detail below.
The major clades of Loasaceae: phylogenetic analysis using the plastid matK and trnL-trnF regions.
Phylogenetic analyses of Loasaceae that apply DNA sequence data from the plastid trnL-trnF region and matK gene in both maximum-parsimony and maximum-likelihood searches are presented. The results

Nectary position, on a collar on which the perianth and androecium are inserted, appears homologous to the ovarian dome position of the nectary among other Loasaceae.
New evidence from the ultrastructural and micromorphological fields in angiosperm classification
This is a survey of ultrastructural and micromorphological data (excluding pollen wall characters) which contribute valuable information for the classification of angiosperms.
Epidermal and seed surface characters of plants: systematic applicability and some evolutionary aspects
There is evidence that these features may be seen primarily under the aspects of reduced ability of plants to contaminate and as temperature control mechanisms of the surfaces, and some evidence for their systematic applicability above the family level.
An ordinal classification for the families of flowering plants
Recent cladistic analyses are revealing the phylogeny of flowering plants in increasing detail, and there is support for the monophyly of many major groups above the family level. With many elements
