Taxonomic Realignments within the Subfamily Pitcairnioideae (Bromeliaceae)
Systematic Botany, 1988In our phylogenetic analysis of the subfamily Pitcairnioideae, three monophyletic groups of genera became evident. These are formally treated as tribes, namely, Brocchinieae (Broc- chinia); Pitcairnieae (Ayensua, Connellia, Cottendorfia, Fosterella, Navia, Pepinia, Pitcairnia, and Steyer- bromelia); Puyeae (Abromeitiella, Brewcaria, Deuterocohnia ...

Molecular Phylogenetics and Evolution, 2009
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 ...

A multivariate analysis of the Pitcairnia palmeri group (Bromeliaceae: Pitcairnioideae)
Phytotaxa, 2018A multivariate analysis of the Pitcairnia palmeri group are presented. Principal Components and Cluster analyses were performed in order to have more accurate information to delimit the species. The analyses showed that the specimens referred to Pitcairnia palmeri var. longebracteata are clearly delimited, while those identified as P.

Nectar Secretion Pattern and Removal Effects in Six Argentinean Pitcairnioideae (Bromeliaceae)
Botanica Acta, 1992AbstractNectar secretion pattern and effects of nectar removal were analyzed in six hummingbird‐pollinated Argentinean Pitcairnioideae: Abromeitiella brevifolia. A. lorentziana, Deuterocohnia longipetala. Dyckia floribunda, D. ragonesei and Puya spathacea. Flower lifetime was determined in each case.

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).

Phylogenetic Relationships of Groups of Genera within the Subfamily Pitcairnioideae (Bromeliaceae)
Systematic Botany, 1988The phylogenetic relationships among the sixteen genera of the subfamily Pitcair- nioideae are resolved with the aid of cladistic methods. Two genera of Velloziaceae (Barbacenia, Vellozia) and three each from the bromeliad subfamilies Tillandsioideae (Glomeropitcairnia, Guzmania, Vriesea) and Bromelioideae (Hohenbergia, Neoregelia, and Orthophytum ...

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.

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.

Reprodução sexuada de Dyckia tuberosa (Vell.) Beer (Bromeliaceae, Pitcairnioideae) e interação planta-animal [PDF]
Revista Brasileira De Botanica, 2006 Bromeliaceae is an important component in several Biomas due to its remarkable ecological diversity as well as biotic interactions. It presents a combination of two reproductive mechanisms: sexual and clonal propagation. We describe in this study the various attributes related to the sexual reproduction of Dyckia tuberosa as well as plant-animal ...

Novelties in Pitcairnia (Bromeliaceae; Pitcairnioideae): three new species from Mexico
PhytotaxaThree new species of Pitcairnia from Mexico are proposed: P. aleserratoae was found in Guerrero, Morelos, and Puebla; P. gracielae known from the Estado de Mexico and Morelos while P. pugana has been collected in Jalisco. Information on distribution, habitat and phenology is provided for each species. The new taxa are compared with P.
