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 ...
COMPARATIVE OVULE ONTOGENY IN SOME MEMBERS OF THE TABEBUIA ALLIANCE (BIGNONIACEAE)
(Univ Chicago Press, 2016-07-01)
Premise of research. Recent phylogenetic studies placed nearly all Neotropical arboreal and shrubby species of the Bignoniaceae (excluding Jacaranda) in the Tabebuia alliance, a clade that includes all of the woody species ...
OVULE, FRUIT, AND SEED DEVELOPMENT OF ORECTANTHE SCEPTRUM AND ITS SYSTEMATIC RELEVANCE TO XYRIDACEAE (POALES)
(Univ Chicago Press, 2017-02-01)
Premise of research. Orectanthe consists of only two species with a distribution limited to the Guayana Highlands, in locations where sample collection is challenging. The genus belongs to Abolbodoideae, one of the two ...
Development of ovule, fruit and seed of Xyris (Xyridaceae, Poales) and taxonomic considerations
(Wiley-Blackwell, 2015-04-01)
The development of the ovule, fruit and seed of Xyris spp. was studied to assess the embryological characteristics of potential taxonomic usefulness. All of the studied species have (1) orthotropous, bitegmic and tenuinucellate ...

Aspectos da ontogenia, ginosporogênese e ginogametogênese em Dasyphyllum brasiliense (Spreng.) Cabrera e Schlechtendalia luzulaefolia Less. (Barnadesioideae-Asteraceae)
(Universidade Federal de Santa MariaBRCiências BiológicasUFSMPrograma de Pós-Graduação em Agrobiologia, 2014-03-14)
Asteraceae has attracted many embryologists because of its high variability of the embryological features. Nevertheless, nothing is known about the embryology of the species basal subfamily, Barnadesioideae. Thus, this ...
Embryology of sunflower Helianthus annuus (Asteraceae)
(Finnish Zoological Botanical Publishing Board, 2008-07)
The abortion of sunflower fruits during different moments of its development could be due to abnormalities in the reproductive process. A comparative study of the sporogenesis, gametogenesis and the development of the ...
