Other claims from this paper (8)

Observation Tripterygium hypoglaucum and T. wilfordii clustered together in plastid phylogenetic analysis.
Observation T. hypoglaucum was polyphyletic.
Observation T. wilfordii was paraphyletic.
Observation Spatial molecular variance analysis identified four groups, broadly consistent with the phylogeny.
Observation Molecular dating placed Tripterygium divergence at approximately 8.13 Ma.
Observation Database DNA regions clustered T. wilfordii with T. hypoglaucum and placed T. regelii separately.
Recommendation The authors propose that T. wilfordii and T. hypoglaucum are conspecific.
Recommendation The authors propose that T. regelii likely is a separate species.
