Very interesting abstract. Is this a type of the R laxa Retzius that Griffith Buck used?

This must be Rosa laxa Retz.

This links to a paper discussing the forms of R. laxa. For instance, the authors note that R. laxa var. tomurensis is a tetraploid variety of the species. However, they suggest that R. laxa var. kaschgarica might be raised to the status of a species.

Xianjiang, China is just over 645 miles from Semey (formerly Semipalatinsk), Kazakhstan, where Prof. Hansen acquired his 'Semi' selection of R. laxa Retz.
