Morphoanatomy of the Ovary and Ovule in Bromeliaceae Subfamily Tillandsioideae and Its Systematic Relevance [PDF]

Botanical Journal of the Linnean Society, 2016
Tillandsioideae are composed of nine genera, most of these with unclear delimitation. The morphoanatomy of ovules and ovaries of 83 species from seven different genera was studied under light or scanning electron microscopy to contribute to the understanding of the relationships in the group.

Stigmatic Diversity in Tillandsioideae (Bromeliaceae): A Search for Homologies

Botanical Journal of the Linnean Society
Abstract Tillandsioideae is the subfamily of Bromeliaceae with the most taxonomic and morphological diversity, leading to still-controversial classification in some clades and species groups. Floral morphology, especially of the stigmas, provides relevant data for the circumscription of genera and species.

Seed morphoanatomy and its systematic relevance to Tillandsioideae (Bromeliaceae)

Plant Systematics and Evolution, 2012
The morphoanatomy of mature seeds of 14 species, representing Vriesea and Tillandsia genera, was investigated in light and scanning electron microscopy to establish structural patterns of the seed coat, endosperm and embryo, allowing the distinction between both genera and contributing to the systematic of Tillandsioideae.

Pollen morphology ofAlcantareagiant bromeliads (Bromeliaceae, Tillandsioideae)

Grana, 2017
AbstractHere we describe the pollen morphology of 19 species of Alcantarea, none of them fully described before, to contribute to the infra-generic delimitation of the genus. Pollen grains are heteropolar, amb ellipsoidal (although spheroidal pollen occurs in Alcantarea aurantiaca, A. burle-marxii, A. glaziouana, A. nahoumii, A.
