Brongniart in part and Crossozamia of Powell.) 
Leaves very variable in size and shape, either ovate oblong 
acuminate, or oblong or linear and oblong acuminate; alk 
regularly pinnate. Pinne more or less horizontal and inserted 
perpendicularly into the rhachis, lanceolate, linear lanceolate, 
oblong, acuminate or obtuse, base contracting suddenly and 
fixed to the anterior side of the rhachis by a more or less 
distinct callosity; solidly coriaceous. Nerves distinct, straight, 
parallel, ending abruptly at the apical margin of the leaflet. 
Popozamites (Fr. Braun.). 
Leaves of medium size. Leaflets distinct, spreading, oblong, 
ovate, and linear oblong, apex obtusely acuminate or rounded, 
gradually narrowed towards the base, sub-pedicellate, pedicel 
articulate, deciduous. Nerves dichotomous at the very base, 
then simple, erect, parallel, then converging towards the apex.

inserted on the upper side of the sub-terete rhachis, unequally

of the leaflet, basilar arcuate, the others sub-arcuate, once or
