At Tas. 4918, we have stated that our Aristolochia Thwaitesii is a native of 
Ceylon ; but our excellent friend Mr. Thwaites says that there is some error in 
this ; and we have reason to believe that the label attached belonged to some 
other plant :—-we think the plant is possibly of Chinese origin. We have never, 
however, seen it but in a state of cultivation, and have no certain clue to its 
native country.
