The movement of involucral bracts of Syngonanthus elegans (Eriocaulaceae-Poales): Anatomical and ecological aspects
(Elsevier Gmbh, Urban & Fischer Verlag, 2009-01-01)
Syngonanthus elegans flowers are distributed in capitula whose involucral bracts open and close in a diurnal rhythm. The anatomy of these bracts was studied to understand how such movements occur and how it influences ...

Joint Segregation of High Glanding with Nectariless and Frego Bract in Cotton
(The Cotton Foundation, 2019-11)
There are mutant alleles in the genus Gossypium that increase the tolerance to insect pests. Among the features that are effective against different insects, high glanding and nectariless increase the tolerance to Lepidoptera ...
Dendroid colleters on vegetative and reproductive apices in Alibertia sessilis (Rubiaceae) differ in ultrastructure and secretion
(Elsevier Gmbh, Urban & Fischer Verlag, 2012-01-01)
In this work we compare the structure and secretion of dendroid colleters on stipules, bracts and sepals of Alibertia sessilis, a non-nodulate Rubiaceae species from Brazilian cerrado, with notes on the plant phenology. ...

Anatomy of scapes, bracts, and leaves of Paepalanthus sect. Diphyomene (Eriocaulaceae, Poales) and its taxonomic implications
(2013-06-26)
Paepalanthus sect. Diphyomene comprises 18 species with a convoluted taxonomic history. Aiming to correlate anatomical structures with the systematics of this group and its relatives, we studied the anatomy of scapes, ...
