The neotropical genus Fosterella L.B. Smith (Pitcairnioideae, Bromeliaceae) comprises about 30 species, with a centre of diversity in semiarid to humid habitats of the Andean slopes and valleys of Bolivia. Morphologic differentiation of species is difficult because of a paucity of diagnostic characters, and little is known about the infrageneric ...

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 ...

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).

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.

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 ...

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.

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 ...

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.
