Abstract:—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 ( mat K gene, rps 16 intron, atp B- rbc L and psb B- psb H intergenic spacers). Sequences were gen- erated for 96 accessions corresponding to 60 species from 18 genera. Among these, 57 accessions repre- sented 22 of the 31 recognized Fosterella species and one undescribed morphospecies. Maximum parsimony and Bayesian inference methods yielded well-resolved phylogenies. The monophyly of Foste- rella was strongly supported, as was its sister relationship with a clade comprising Deuterocohnia , Dyckia and Encholirium . Six distinct evolutionary lineages were distinguished within Fosterella . Character map- ping indicated that parallel evolution of identical character states is common in the genus. Relationships between species and lineages are discussed in the context of morphological, ecological and biogeograph- ical data as well as the results of a previous amplified fragment length polymorphism (AFLP) study.
