THE SUNDEWS. 



Hence, then, this aggregation is neither a cause nor 

 a consequence of inflection. Whatever its cause may 

 be, it appears to be invariably accompanied by an 

 increased secretion of the glands, and the dispersion 

 of the masses, in like manner, indicates a diminution 

 in the amount of viscid matter secreted by the glands. 

 The shorter central tentacles, which have a green 

 pedicel, exhibit the same phenomenon, with the 

 exception that the aggregated masses partake of the 

 green colour of the cells. The colour of the aggre- 

 gated masses being of course dependent upon the 

 colour of the contents of the cells. 



The experiments on the Sundews have been for the 

 most part conducted with the little round-leaved 

 Sundew, but the other two English species have like- 

 wise been examined, and found to correspond in all 

 essentials with its fellow species. This has been done 

 both in England and America. A species with very 

 long slender leaves,^ which grows abundantly in New 

 Jersey, has been tested in a similar manner. One 

 person writes:- "I found it in full bloom, and growing 

 as thick as it could well stand, on either side of an 

 extensive cranberry plantation. This charming plant

 like substance exuding from the glands (the glands
