“Note on Professor Williamson’s paper 'On an Unde- 
scribed Type of Calamodendron from the Upper Coal 
Measures of Lancashire,’ ” by E. W. Binney, F.R.S., F.G.S. 
I had not the pleasure of hearing Professor Williamson’s 
paper on Calamopitus read, but from the abstract printed 
in the Society’s Proceedings it is quite evident that the 
Professor’s plant is very different from the Calamodendron 
commune described by me in the last volume of the Trans- 
actions of the Palseontographical Society. I have found 
casts of the pith of the Sigillaria vascularis which ordinary 
collectors would call a Calamites , and in two specimens of 
Dadoxylon I have met with Calamites cannceformis as the 
pith of one, and C. approximatus as the pith of the other. 
Sternbergia has long been known to be the pith of Dadoxy- 
lon, so now the genus Calamites in all probability will have 
to be very considerably modified and some of its species 
classed with other genera. 
Some years since that profound botanist the late Dr. 
Robert Brown, in a memoir printed in the Transactions of 
the Linnaean Society, vol. xx. p. 3, 1851, gives some account 
of Triplosporites, an undescribed fruit which had lately 
Proceedings— Lit. & Phil. Society.— Vol. VIII. No. 5— Session 1868-9.
