plant interesting by its structure and beauty, and so closely
allied to the SphmrosygcB, which have already appeared. Monormia
seems to differ from SplieBrozyga chiefly in possessing a
gelatinous branching matrix, so loose in structure that it can
hardly be called a frond, surrounding the spirally-twisted filament.
This filament is of indefinite length, having many connecting
cells : the filaments of the Sphmrozygce, on the contrary,
are generally short, with seldom more than one or two connecting
cells. The fructification in both appears formed on the same
type.
