Abstract
Mesophyllum incisum is reported and studied for the first time in South Africa. It has a th all us surface (SEM) with
Leptophyturn-type epithallial cells. TetraJbisporangial conceptacles are mound-like and lack a peripheral rim but
have a flattened pore plate. The rosette cells surrounding the tetrasporan gial po res are distinct from su rrounding
roof cells (SEM, surface view) in be ing narrower, and sunken below the level of the surrounding pore plate. The
cells of filaments bordering the tetrasporangial conceptacle pore canal differ from the othe r roof cells within the
pore plate in being more elongate, narrower, and often more densely staining. Pore canal filaments also generally
contain fewer cells than the surrounding filaments of the pore plate and th e pore can al is more-Dr-less parallel
sided. Our material agrees closely with the species as reported in Australia.
