<p><a></a><a>Historical
processes during the Quaternary are likely to have left a signature on the
geographical distribution of intraspecific genetic variation. In particular,
high genetic uniqueness could be expected within glacial refugia for multiple
species. We aimed to test this for plants in China and whether multi-species
hotspots of genetic diversity are good indicators of glacial refugia in this
region. From chloroplast DNA haplotype data for 116 species we calculated two
local genetic diversity metrics for each species: haplotype genetic richness
and genetic uniqueness. From these two, only uniqueness could reliably identify
refugia, whereas richness may indicate either glacial refugia or areas
recolonized by genetic lineages from different refugia in the postglacial
period. Our results suggest the occurrence of numerous cryptic refugia and
their likely importance in the maintenance and evolution of the Chinese flora,
and indicate that an approach that locates geographic hotspots of genetic
diversity data can reliably identify refugia.</a></p>
