of the leaves of Artkropitys as well as of its stem. Hence it would 
seem to be a legitimate inference that there is a close relationship 
between Calamostachys Binneyana and that type of Catamites which 
is known as Artkropitys. We mighty perhaps, without much risk of 
error, go further than this, and conclude that the one is actually the 
spore-bearing shoot of the other, but in a case of this kind it is 
better to keep our inferences well within the range of the facts on 
which they are based.
