Account of some Mule Plants. 



less exuberant produce must, however be expected ; for sugar 

 appears to be an article, the production of which requires a 

 large expenditure of the vital juices of the tree. 



We possess, I believe, in the Flemish and Kentish Cherry, 

 two varieties of the same species with the Morello ; and the 

 Toussaint, and one or two others described by Duhamel in 

 his Traites des Arbres Fruitier s, appear to belong to the same 

 family. The Morello Cherry tree is obviously the " Cerisier 

 tres fertile" of this author. 



I have seen the blossoms and fruit of the Morello Cherry 

 tree bear, in the forcing-house, the temperature of seventy 

 and even of eighty degrees, without any injurious or peculiar 

 effects, except that the plumules of the seeds produced in 

 such high temperature expanded with something very like 

 blossoms upon the points. Small white leaves, in every 

 respect similar to the petals of blossoms, were in many in- 

 stances arranged as in a perfect blossom, which withered and 

 died, whilst a bud upon the lower part of the stem vegetated, 

 and the period of puberty in the plants did not subsequently 

 appear to be at all accelerated by the operation of the high 

 temperature in which the seeds had been ripened. 



I do not offer plants of the Mule varieties above-mentioned 

 of the Cherry, to the Society, because I feel quite confident 

 of their being wholly useless.
