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.

p. 9: In 1900 he [E. H. Wilson] collected R. helenae, which was not introduced until 1907.
p. 12-13: From late 1906 to 1909, financed by Harvard’s Arnold Arboretum, Wilson again scoured China for plants. Roses he had seen and collected in 1900 and 1901, such as R. gentiliana, R. helenae, R. giraldii var. venulosa, and R. sertata, he introduced in 1907 or shortly thereafter. ...
Rosa helenae was named for E. H. Wilson’s wife, who died with him in a car accident in 1930. This is another white, scented species rose exhibiting large clusters on very prickly stems. Found from Shensi province, south through eastern Sichuan and western Hupeh, its tangled proliferation grows along wayside thickets and stream-side masses, and rambles vigorously over small trees at the edges of woods. When he first saw this musk rose, Wilson wrote that it “filled the air with its soft fragrance.” The seeds collected in 1907 flowered at the Arnold Arboretum in 1913, proving the species “perfectly hardy.” R. helenae is closely related to the Himalayan R. brunonii
