Abstract
Systematic and biogeographic relationships of Hypopterygium populations from three European localities (glasshouses of the botanical gardens of Glasgow and Berlin, Bussaco arboretum in Portugal) are evaluated based on DNA sequences and AFLP fingerprinting. Maximum parsimony analyses based on combined plastid trnL intron and nuclear ribosomal ITS2 sequences confirm that all three populations belong to the widespread, mainly pantropical and warm-temperate H. tamarisci. Neighbour joining analyses based on AFLP banding patterns from four primer combinations indicate a close relationship with the Australasian variant of H. tamarisci and an Australian or New Zealand origin of the populations. At least two independent introduction events from the Australasian region are indicated, one concerning the closely related specimens from Glasgow and Berlin, and the other the Portuguese specimen, the latter probably originating from southern New South Wales.
