SEED MORPHOLOGY OF THE SUBFAMILY PITCAIRNIOIDEAE (BROMELIACEAE) AND ITS SYSTEMATIC IMPLICATIONS
American Journal of Botany, 1988Scanning electron microscopy (SEM) observations of seed samples of 75 species representing fourteen Pitcairnioideae genera combined with some seed developmental and germination data revealed six classes of seed morphology (the Dyckia type, Puya ferruginea type, Puya hamata type, Fosterella type, Navia type and the Brocchinia type).

We applied a series of intra- and interspecific in situ cross-pollination experiments under greenhouse conditions to evaluate the breeding systems in four Fosterella species (Pitcairnioideae s.str.; Bromeliaceae). Viable hybrids were produced between each pair of the investigated species, suggesting that reproduction barriers may be low also under ...

A new Dyckia species (Bromeliaceae, Pitcairnioideae) from the Brazilian Northeastern region
Phytotaxa, 2014A new species of Dyckia (Pitcairnioideae) is described and illustrated here. Dyckia piauiensis sp. nov. was found in the state of Piauí, in northern Brazil, in very dry Cerrado vegetation and cultivated by the first author. This new species’ closest relative is Dyckia pernambucana, but differs from it by its larger and retrorse spines, shorter ...

The about 31 species of Fosterella L.B. Sm. (Bromeliaceae) are terrestrial herbs with a centre of diversity in the central South American Andes. To resolve infra- and intergeneric relationships among Fosterella and their putative allies, we conducted a phylogenetic analysis based on sequence data from four chloroplast DNA regions (matK gene, rps16 ...

Puya raimondii (Pitcairnioideae, Bromeliaceae) and birds: an hypothesis on nutrient relationships
Canadian Journal of Botany, 1980We recorded observations on the relationships between Puya raimondii and the associated bird community in a dry grassland habitat in the high Andean plateau (altiplano or puna) of southeast Peru. From field evidence, we hypothesize that P. raimondii benefits from its association with birds through enhanced nutrient supply. Both bird droppings and dead

Pitcairnia encholirioides is a threatened species endemic to the inselbergs of the Atlantic Forest. The study of the embryogenesis and endospermogenesis of Pitcairnia encholirioides aims to the establish guidelines for its in vitro propagation.

The genus Dyckia (Bromeliaceae) comprises 147 species that are distributed in Brazil and adjacent countries. Many species are rare and narrow endemics. We used 454 pyrosequencing to isolate 1,587 microsatellite loci in Dyckia marnier-lapostollei. Of 50 loci that were selected for primer design, 15 markers proved to be polymorphic in five populations ...
