 Hybrids of this and R. Carolina L. (R. humilis Marsh.) are frequent. 



5. R. gallica L.

of Cayuga Fl.)

[R. virginiana Mill. (R. lucida Ehrh.? and of Cayuga Fl.) 



Plants from n. of Eddy Pond, and from near the Junius ponds, are referred by 

 Dudley to this species. True R. virginiana is a plant of the coastal region and 

 apparently does not occur in New York State except in the vicinity of New York 

 City. A specimen from Dudley in the Gray Herbarium, labeled by him " R. 

 humilis: Old fruiting stem very prickly, near Case. Cr. Ithaca, Oct. 1885," bears 

 in Watson's handwriting the correction "R. lucida," and is apparently a hybrid of 

 R. Carolina and R. Eglanteria. It was probably on this specimen and Watson's 

 correction that Dudley inserted R. lucida in the Cayuga Flora.'] 



8. R. Carolina L. (See Rhodora 20: 91. 1918. R. humilis of authors and of Cayuga 



Fl.) Dwarf Rose. 

 Borders of dry thickets and hedgerows, also by roadsides, in mixed clayey and 

 sandy or gravelly soils ; common. June 20-July.
