New Coat-Prants or Nova Scorra.—At the Newcastle Meeting of the 
British Association was read a paper, by Dr. Dawson, on Lepidophloyos Aca- 
dianus and Lepidodendron corrugatam, two plants very characteristic, in Nova 
Scotia, of the lower coal-measures associated with the lower carboniferous lime- 
having the leaf-bases preserved, with the cone-scars, but wanting vascular 
scars; but he was in doubt as to the claims of the name Ulodendron on the 
ground of priority. It appeared to him that the generic names Ulodendron, 
Lomatophloyos, Leptorylum, Pachyphleus,and Fothrodendron, should be abo- 
lished in favour of Lepidophloyos, : any of these names had priority in 
date. The second plant described was the idodendron corrugatum, one of 
the most abundant in the lower peru -measures of Nova Scotia and New Bruns- 
wick. The species was remarkable for its variability, and also for the dissimilar 
appearances of old stems and branches occasioned by the separation of the 
areoles i in the growth of the bark, instead of the areoles themselves increasin 
e, as in some other Lepidodendra.—Mr. Sorby remarked - the ten- 
dency of the paper was to show that there were a number of genera, that ap- 
peared to be quite distinet, that were only different stages of utilis and 
growth of the same plant.— The President said that Dr. Dawson had for many 
years worked the fossil botany of the coal-fields of Nova Scotia in a manner de- 
serving of praise. This subject naturally commended itself to attention in the 
town of Neweastle, where Hutton and Lindley did so much to establish the 
knowledge of the principal forms of the coal-plants. The paper was one of a 
series of communications by Dr. Dawson sent to this country, giving facts and 
deductions with respect to the boundaries of the several species and genera of 
coal-plants, which showed that simplification might be introduced in the 
Sadek Mr. Binney, of Manchester, who first laid it down = Stigmaria were 
the roots of certain of the p ]-plants, 
he would therefore call o MEUM Binney to tell them what he thought of the 
conclusions of the author P the paper, and more especially of the fusion he 
would make of sundry genera and species.—Mr. Binney scarcely thought they 
would be justified in going so far as was suggested, but he approved of much 
that was said in the
