Pinnae probably long and narrow; pinnules small, narrow, quite parallel-sided, alternate, or sub-alternate, decurrent, attached by their whole bases, generally distinct from one another, but sometimes slightly confluent, not constricted at the base; apices broadly rounded and not in any way acuminated; veins distinct, about ten at the basal end of pinnules, each bifurcating at about half the length of the leaflet, direct, not converging towards the apex; rachis not very broad, distinct, and longitudinally striate. Obs. A few examples of this plant have come under my notice, but all presenting similar characters. Strictly speaking, the dichotomy of the veins would remove the species from Pterophyllum, where they are always described as simple. On the other hand, in those genera in which the simplicity of the venation is lost, the pinnules are either inserted on the rachis by a callosity, as in Zamites; with an articulated base, as in Otozamites; by an attenuated and articulated base like Podozamites; or partially united, as in Ptilophyllum. In the present case the pinnules are most certainly decurrent, and for that reason I prefer to provisionally retain the plant in Pterophyllum. In the form of the pinnules and their separation from one another, there is...
