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.

A new species of Werauhia (Bromeliaceae: Tillandsioideae) from the Brazilian “Hylaea”

Phytotaxa, 2020
The authors describe and illustrate Werauhia hylaeana, a new species of Tillandsioideae (Bromeliaceae) from the Amazonian “Hylaea” of Brazil. It is related to W. gladioliflora, but differs in its stature, leaf blade, and inflorescence size, in the shape of floral bracts, sepals, and petals.

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.

A New Tillandsia (Tillandsioideae, Bromeliaceae) Species from the Copalita River Canyon, Oaxaca, Mexico

Phytotaxa, 2020
A new saxicolous species from the steep cliffs of the Copalita river canyon is described and illustrated: Tillandsia joel-mandimboensis. We present detailed morphological comparisons of the new species to other morphologically-related saxicolous Tillandsia species also endemic to river canyon cliffs, complemented with information on their habitat ...

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.

Two new species in Tillandsioideae (Bromeliaceae) of Machu Picchu, Peru

Phytotaxa, 2012
Two new species belonging to the subfamily Tillandsioideae from Machu Picchu, Cusco, Peru are described and illustrated here. The new species Tillandsia machupicchuensis is close to T. tovarensis and the other new species Guzmania inkaterrae is close to G. morreniana and G. tenuifolia. Both species are abundant in the area.
