Contribution to the study of the genus Fosterella (Bromeliaceae: Pitcairnioideae) in Brazil
Phytotaxa, 2019The pitcairnioid genus Fosterella currently comprises 31 species distributed from Mexico in North America, along the eastern slopes of the Andes in central South America, Southern Peru to northern Argentina, encompassing western, northern and southeastern Brazil and northern Paraguay.

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 ...

Taxonomic review of the Dyckia remotiflora complex (Bromeliaceae, Pitcairnioideae)
PhytotaxaSeveral species complexes of Dyckia s.s. have been investigated in recent years, with the taxonomy of the genus regarded as one of the most challenging within the family. In this study, we propose the circumscription of the Dyckia remotiflora complex and present a taxonomic-nomenclatural revision for the included taxa: D. remotiflora var.

Pitcairnia anarosae (Bromeliaceae; Pitcairnioideae) a new species from the state of Oaxaca, México
Phytotaxa, 2020Pitcairnia anarosae, known until now from the municipality of San Juan Colorado, Oaxaca, Mexico, is described and illustrated. The new species is compared with P. singularis, from which differs by the plant height (19–40 vs 15–25 cm) the number of leaves (5–8 vs 3–4), and the morphology, color (red vs white) and length of flowers.

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).

Transferability and characterization of microsatellite markers in five Bromeliaceae species belonging to the subfamilies Pitcairnioideae and Bromelioideae [PDF]
Biota Neotropica, 2012 Microsatellite markers previously developed for Pitcairnia albiflos Herb. and Pitcairnia geysksii L.B.Sm. were used in cross-amplification tests of five other Bromeliaceae species. Ten (76.9%) out of the 13 evaluated pair of primers had positive results for some of the species tested.

Two New Species of Hechtia (Bromeliaceae, Pitcairnioideae) from Western Mexico
Brittonia, 1993Hechtia glauca andHechtia iltisii are described as new and illustrated. Among the Bromeliaceae H. glauca is unusual in its glabrous, glaucous leaf surfaces. Inflorescence and floral dimorphisms are discussed forH. glauca andH. iltisii. A key to species ofHechtia from Novo-Galiciana and adjacent parts of Michoacan is included.

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 ...

Plant Systematics and Evolution, 2015
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 ...

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
