Phylogenetic relationships of the silver saxifrages (Saxifraga, sect. Ligulatae haworth): implications for the evolution of substrate specificity, life histories, and biogeography.

Abstract excerpt

The silver saxifrages (Saxifraga sect. Ligulatae Haworth; Saxifragaceae) exhibit remarkable variation of substrate specialization, with strictly calcicole to calcifuge species, as well as life histories which range from semelparity to iteroparity. They occur almost exclusively in the European mountain ranges and display high levels of endemism. Sequences from chloroplast and nuclear ribosomal DNA were obtained to...
