Comment:

Stipitate glands on the hypanthia and pedicels of this showy pink rose help distinguish it from R. blanda and R. virginiana. Technical details for stipules and prickles must also be determined.

On Mount Desert Island this rose is found both inland and growing near the ocean.

Ultraviolet light brings out the texture and iridescence of the rose petals which are moderately UV-absorbing.
