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.

"ROSA MACOUNII - one of our native rose species, with round, orange-colored hips. I selected a strain with extra deep pink flowers, single, of course."

Percy Wright Catalogue - Hardy and Semi-Hardy Roses - ca 1949 p.4

R. blanda also gives fertile vigorous hybrids with the diploid R. woodsii. An intergrading series between these forms makes it hard to classify the diploid roses of the northern Great Plains region. In herbaria these forms are usually called R. macounii, a species that is probably a definite ecotype of R. woodsii. Lunell's description of R. naiadum Lunell covers this hybrid, which resembles R. woodsii and may be used to designate intermediate forms.
