as well as certain East Asian allies, in one species, Smilax herbacea, 
while others have attempted segregations based upon the shape 
of the branchlets, the length of the peduncles, the number of 
primary veins, and other characters which field-study proves too 
variable for certain use. But it has gradually become apparent
