Professor W. C. Williamson, LL.D., F.R.S., laid before 
the society a communication on the relations subsisting 
between the Calamodendra of Antun and Chemnitz and 
the ordinary Carboniferous Calamites. M. Renault considers 
that the former plant belongs to the group of the Gymnos- 
perms, and further, that some spikes of fructification which 
he has obtained are the staminiferous organs of Calamo- 
dendron, the supposed anthers of which are filled with 
Pollen-grains. Professor Williamson first called attention to 
the several p)oints of resemblance and of difference between 
some sections of Calamodendron from his cabinet, and 
similar ones of Calamites. At the same time he showed 
that a Calamite which he described in the Memoirs of the 
Proceedings — Lit. & Phil. Soc. — Vol. XXVI. — No. 1. — Session 1886-7.
