Page 130 - BODIES consisting of straight or flexuous stipes (simple or conjoined at base?), with alternating and widely diverging branches : branches long, simple or ramose, in the same manner as the stipe. Substance fibrous or striate; the main stipe and branches marked by a longitudinal central depressed line, indicating the axis. Cellules or serratures unknown.
Page 128 - Flabellate fronds, with numerous slender bifurcating branches proceeding from a strong stem or axis. Branches and divisions celluliferous on one side, the opposite side striate ; sometimes distantly and irregularly united by transverse dissepiments.
Page 126 - Frond plant-like, rooted ? simple or branching. Branches and branchlets plumose, the pinnules rising alternately on opposite sides of the branches ; celluliferous on one face only : branches cylindrical or flattened. Substance corneous, dense ; apparently smooth exteriorly, or corrugated by compression, or during fossilization.

Branches celluliferous on one side : cellules appearing sometimes as simple indentations on the surface, and sometimes distinctly angular, with the denticles conspicuous. In some specimens the cellules are indicated by prominent pustule-like elevations, arranged along the centre, or in subalternate order on one face of the branch.
