44^ CISTACEAE 



3. C. canadense (L.) Britton. In dry rocky or sandy soil: Me. 



to Ont., Wise, N. Car. and Ky. 



Common throughout the range, but not specifically known from 

 the mountains of the Catskills and of Pa. 



4. C. dumosum Bicknell. Dry soil: E. Mass. and L. I. 



Known, in our area, only from the Hempstead Plains of L. I. 



The reported occurrence of C. corymbosum (Michx.) Britton, in N. J. is based on a 

 very old specimen collected in"N. Jersey." The specimen may be from further south, 

 as the species has never since been collected in the state.
