It might be cultivated without difficulty with us; it supported last winter 
a severe degree of cold without appearing to suffer the least, and it 
has already produced an abundant supply of a rhubarb which has all the 
physical charaeters of the best Asiatie kind. These characters are the

structure of a dicotyledonous root. There was no reason to suppose 
that it would be otherwise, or that any difficulty will be experienced in

stem, and it is not surprising that it should be characterized by a special 
structure, which will be, without doubt, a practical and ready means of 
recognizing and distinguishing the products of inferior quality with which 
the world is inundated.— [Translated from the eport in the * Revue
