Woods. Fl. May. T? .-— The late Mr. Templeton observed the 

 small red-fruited wild Cherry, which he supposed to be the Prunus 

 Cerasus of Linnaeus, growing abundantly on the banks of Lough 

 Neagh, and many other pluces in the north of Ireland. He also ob- 

 served the small black fruited wild Cherry, growing on the banks of 

 Lough Neagh more sparingly. The black fruited variety he supposed 

 to be the true Prunus Avium of Linnaeus. Both kinds are well 

 known in Scotland as the red and black Geen. The fruit of the latter 

 is sweet and much prized, the former is very acid, and Mr. Templeton 

 states it is not eaten by birds. To the black fruited variety he sup- 

 posed all our cultivated Cherries belong, except, perhaps, the Morella, 

 which he thought might belong to the other.
