HelpMeFind's future is in your hands - Please do not take this unique resource for granted.

Your support of HelpMeFind is urgently needed. HelpMeFind, like all websites, needs funding to survive. We have set a premium-membership yearly subscription amount as low as possible to make user-community funding viable.

We are grateful to the many members who have signed up so far, but the number of premium-membership members remains too small for us to sustain the current support and development level. If you value HelpMeFind and want to see it continue we need your support too.

Yearly membership is only $2.00 per month and adds a host of additional features, and numerous planned enhancements, to take full advantage of the power and convenience of HelpMeFind. Click here to start your premium membership..

We of course also welcome donations of any amount. Click here to make a donation. Donations of $24 or more receive a thank-you gift of a 1-year premium membership.

As far as we have come, we feel HelpMeFind is still in its infancy. With your support we have so much more to accomplish.

This is obviously not the Rosa kamchatica described by Ventenat in 1800-1803.

Rosa rugosa Thunb. ex Murray
HANS HENRIK BRUUN

No subspecies of R. rugosa have been recognized in the British Isles. Despite the many cultivated varieties of the species, mainly forms close to the wild type are seen naturalized. However, naturalized clones may be confused with R. x hollandica (syn. R. x kamtchatica). This taxon differs morphologically from R. rugosa by having soft-textured, dull leaflets, without prominent veins, less prickly stems, conspicuously glandular sepals, and smaller flowers and hips (Rutherford 1990).
