3.— ANN UFA RIEAE. 
Genus — ANNULAPiJA, Brongniart, 182S. 
(Prodrome, p. 155.) 
Ohs . — This genus contains herbaceous plants, the stems of which arc 
articulate subulate, and divided by solid diaphragms at the joints. Branches 
pinnate. The leaflets are disposed round the diaphragms in whorls, and as 
the margin of the diaphragm is thickened it appears in the impression as a 
horizontal ring, round which the leaflets are arranged. They are of various 
shapes, lingulately, elongatcly, or spathulately lanceolate, thickish, generally 
horizontally spread out round the ring mentioned, with a central nerve. 
The genus has its widest distribution in the true Co.al Measures of 
Europe, where also its fructification is known. In Australia the genus is 
represented, I think, by some leaf- whorls, which occur in coal shale below 
the Upper Marine beds.

Ohs. — This is the only hitherto known species of Annularia from the 
Australian Coal beds. It resembles somewhat Annularia longifolia, Bgt., 
but the leaflets are not so long, are thinner in their substance, and the whole 
plant appears to have been much more tender. In the same way the 
Australian species is distinct from A. sphenophylloides, Zenk., and Annularia 
rad lata, Bgt. 
There is one circumstance to be mentioned now. In his Jura Elora of 
the Kusnezk Basin in the Altai Mountains,* Prof. Schmalliauscn lias described 
a genus of coniferous plants under the name Cyclopitys, which has its leaves 
also arranged in whorls, and which to some extent bears resemblance to 
Annularia. In a subsequent paper of his, Professor Schmalhausen f has
