and porose. Branch-leaves large, wide-oval, with hyaline border on the 
cucullate apex ; margin widely inrolled for some distance down the 
leaf; on the inner oa only near the lateral mare ne, with large 
round pores; on the r surface with membran e-gaps near the

rectangular, chlorophyllose cells only; in the apical half and near 
the lateral margins down to the base, of both kinds of cells; pores 
on the inner surface numerous near the margins; on the outer
