Morphology and development of anthers and ovules in Croton and Astraea (Euphorbiaceae)
(Wiley-Blackwell, 2011-01-01)
We examined the embryological development of anthers and ovules from Astraea (A. lobata and A. praetervisa) and Croton (C. floribundus, C. fuscescens, C. glandulosus, C. lundianus, C. piptocalyx, C. urucurana and C. ...

Desenvolvimento de óvulo, fruto e semente de Xyris (Xyridaceae, Poales)
(Universidade Estadual Paulista (Unesp), 2014-03-11)
Xyris is the largest genus of Xyridaceae, however there are few studies on its embryology and seed micromorphology. This thesis aimed to describe the development of ovule, fruit and seed of Xyris species in a comparative ...
Embryology and seed development of Blastocaulon scirpeum and Paepalanthus scleranthus (Eriocaulaceae)
(Urban & Fischer Verlag, 2004-01-01)
The embryology and seed structure of Blastocaulon scirpeum (Mart.) Giul. and Paepalanthus scleranthus Ruhland were studied in order to contribute to the embryology of Eriocaulaceae and supply data for future taxonomic ...
Comparative embryology and taxonomic considerations in Eriocaulaceae (Poales)
(2012-01-01)
The genus concept within Eriocaulaceae is widely discussed because it is mainly based on a small number of floral characteristics of unknown functional and evolutionary significance. The aim of the present work is to ...

Ovule, fruit and seed development in Abolboda (Xyridaceae, Poales): implications for taxonomy and phylogeny
(Wiley-Blackwell, 2014-05-01)
Xyridaceae belongs to the xyrid clade of Poales, but the phylogenetic position of the xyrid families is only weakly supported. Xyridaceae is divided into two subfamilies and five genera, the relationships of which remain ...
Anther, ovule and embryological characters in Velloziaceae in relation to the systematics of Pandanales
(2011-01-01)
Velloziaceae are a monocot family of five genera and c. 250 species (Mello-Silva, 2009). The family is now assigned to the order Pandanales, a small but morphologically diverse monocot order of five families: Cyclanthaceae, ...
