It is almost unnecessary to remark that the 

 botanical name of this tribe is derived from the 

 Latin convolvo, from its entwining character. The 

 name Calystegia is formed of two Greek words,

 adapted to the plants it distinguishes, in allusion to 

 the office of the bracteas before referred to. 



Most of the European names are synonymous 

 with our bindweed and withiwinde.
