Molecules and morphology in concert. II. The Festuca brachyphylla complex (Poaceae) in Svalbard
We used a combined molecular and morphological approach to unravel variation in the autogamous Festuca brachyphylla polyploid complex in the arctic archipelago of Svalbard. Forty populations were analyzed for random amplified polymorphic DNAs (RAPDs) and 46 morphological characters. Eighteen RAPD mu...

We used a combined molecular and morphological approach to unravel variation in the autogamous Festuca brachyphylla polyploid complex in the arctic archipelago of Svalbard. Forty populations were analyzed for random amplified polymorphic DNAs (RAPDs) and 46 morphological characters. Eighteen RAPD multilocus phenotypes were observed in the 86 plants analyzed, based on 30 polymorphic markers. Multivariate analyses of the RAPD data revealed four distinct groups of multilocus phenotypes; in contrast, the variation was more or less continuous in multivariate analyses of the morphological data. However, we identified several individual morphological characters that unambiguously discriminated among the four groups of RAPD multilocus phenotypes. Analysis of type material suggests that the four groups in Svalbard can be referred to Festuca baffinensis, F. brachyphylla, F. hyperborea , and F. edlundiae. This study shows that concerted analysis of molecules and morphology is a powerful tool in low‐level taxonomy. |
