Rosa nutkana Presl var. hispida Fernald. Plants can intergrade with Rosa woodsii making identification a challenge. R. nutkana has usually solitary flowers as these plants had whereas R. woodsii has several flowers usually in cymes that are smaller. R. nutkana has singly serrated leaves compared to leaves that are doubly serrate with R. woodsii (except in our area that is a variable characteristic). The bee was fairly small.June 14, 2012, Burch Hollow, Pipeline Trail, Millcreek Canyon, approx 5390 ft. elev.

Rosa nutkana Presl var. hispida Fernald. As described by Holmgren et al (1997), both R. nutkana and R. woodsii are described as seldom or not having gland-tipped leaves. Arnow (1980) however indicates that R. nutkana, does have gland-tipped leaves. Some of the teeth in the picture above do appear to have glands but it is difficult to tell. Both authors agree that the teeth can be singly to doubly toothed although the variety of R. woodsii that occurs in our area appears to more often be doubly serrated and/or have more irregularly serrated leaves than R. nutkana.June 14, 2012, Burch Hollow, Pipeline Trail, Millcreek Canyon, approx 5390 ft. elev.
