Anther wall development, microsporogenesis, and microgametogenesis in abolboda and orectanthe: contributions to the embryology of xyridaceae (poales)
(Univ Chicago Press, 2015-05-01)
Premise of research. Xyridaceae includes two subfamilies with a total of five genera. Xyridoideae has only the single genus Xyris, and Abolbodoideae includes the remaining genera. The inter- and intrafamilial relationships ...
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 ...

(Torrey Botanical Soc, 2015-07-01)
Xyridaceae comprise two subfamilies: Xyridoideae and Abolbodoideae, which are morphologically distinct. Orectanthe belongs to Abolbodoideae and comprises two species with restricted distribution. The anatomy of root, stem, ...
Embriogênese e desenvolvimento pós-seminal de Xyridaceae e Mayacaceae e anatomia floral de Xyris, com ênfase na evolução de caracteres
(Universidade Estadual Paulista (Unesp), 2018-08-30)
Xyridaceae e Mayacaceae são famílias relacionadas, incluídas na ordem Poales. Xyridaceae é grupo-irmão de Eriocaulaceae e ambas as famílias formam o clado xyrídeo. Já Mayacaceae tem posição filogenética instável, emergindo ...
FLORAL ANATOMY of XYRIDS (POALES): CONTRIBUTIONS TO THEIR REPRODUCTIVE BIOLOGY, TAXONOMY, and PHYLOGENY
(Univ Chicago Press, 2012-09-01)
Xyridaceae, Eriocaulaceae, and Mayacaceae form the xyrid clade, which is weakly supported in Poales. The floral anatomy of xyrid species was studied, to contribute to the understanding of the relationships within the group. ...
