On Clovers.

Secondly. The Trifolium Pennsylvanicum, gathered by me in 

 the woods on the banks of the Hudson, is the true T. medium. 

 Don remarks of it, "very like T. medium or T. p7-atense," which 

 suggests that after all it may be but a variety of the latter. It 

 is, as with us, of a large and handsome form. 



Thirdly, Tiie Trifolium agrarium, Golden Clover. This I take 

 to be a cultivated form of the T. pratense, but I do not know it. 



Our small native list of clovers seems very insignificant by 

 the side of Don's descriptive list of one hundred and sixty-six 

 species. This list, however, 1 think, is greatly made up of 

 varieties, into which the different species seem to have a great 

 aptitude for running, a point of considerable importance, as 

 showing that it is within the cultivator's power to produce new 

 and doubtless valuable forms as the result of care and attention. 



But again, few as are our native forms, so many of them are 

 insignificant in a farming point of view, that 1 shall only direct 

 especial attention to the following : —

1. The Trifolium pratense of the meadow is met with in most 

 parts of England, and seems to flourish in the drier pastures if 

 not too often mown, for the scythe not only robs it of manure, 

 but hinders the growth of fresh seed. In this case the plant is 

 soon renewed by dressings of any kind of compost provided 

 lime be present in sufficient quantity, a mixture of road dirt —
