Embryology and fertility of the natural tetraploid Lessingianthus plantaginoides (Asteraceae, Vernonieae): taxonomic implications
Lessingianthus plantaginoides (Vernonieae, Asteraceae) is a small natural tetraploid shrub that inhabits rocky highlands from South America. The population studied inhabits and covers an extensive region of a private reserve ...
Floral structure, development of the gynoecium, and embryology in schinopsis balansae engler (anacardiaceae) with particular reference to aporogamy
(University Of Chicago Press, 2016-04)
Premise of research. Most studies of Anacardiaceae embryology have focused on seed and fruit development in different genera. None of them, however, included species of Schinopsis. Considering the absence of embryological ...
