Abstract
The systematics of the mainly yellow flowered Gagea species complex (Liliaceae) has long been considered difficult because only a few phenotypic features within this genus and as a result of hypothesized interspecific hybridisation. A molecular phylogenetic study of seven Gagea species (G. bohemica, G. lutea, G. minima, G. pomeranica, G. pratenis, G. spathacea and G. villosa) from Germany has been undertaken, based on plastid DNA sequences (trnL(UAA)-trnF(GAA), psbA-trnH) and on the nuclear ribosomal internal transcribed spacer (ITS). Sequence divergence within the Gagea species ranges up to 15.5% for psbA-trnH, 22.0% for trnL-trnF and 23.7% for ITS (ITS1 + 5.8S rRNA + ITS2). Two subspecies of Gagea bohemica: G. bohemica subsp. saxatilis and G. bohemica subsp. bohemica are characterized by trnL-trnF data and morphological features. Analysis of the ITS region shows that G. pomeranica represents a hybrid of G. pratensis and G. lutea. Lloydia serotina was initially used as an outgroup species, but it was placed within the investigated Gagea species in the psbA-trnH and the trnL-trnF phylogenetic tree.
