[MATTHEW] A REVIEW OF THE LITTLE RIVER GROUP 105 



Annularia — whorls at the nodes, usually flattened to the plane of 

 the stem, possessing an annulus. 



AsteropJuyUites — whorls spreading or ascending, annulus absent. 

 Sec. 1, the leaves evenly spread around the axis. Sec. 2, leaves in tufts 

 around the axis. 



SphenophyUum — leaves few, with spaces between at the node (like 

 the above Sec. 2 of Asterophyllites) . 



Calamités — stem (as preserved) fistulous, and having ribs alternat- 

 ing at the nodes. 



A stero calamité s — Stem (as preserved) fistulous and having opposite 

 ribs at the nodes.

In the material referred by Sir William Dawson to this species 

 I find many examples that agree better wij;h Calamités Suckovii. With 

 his homotype figured in Fossil Plants of the Devonian and Upper Silu- 

 rian of Canada) may be included such of the wide-ribbed stems as do 

 not show the plano-convex ribs of C. Suckovii.
