 acumen flexuous or when dry serpentine-corrugate, borders more or 

 less recurved but not reflexed, subentire or faintly denticulate above ; 

 lower basal cells wide and sub-rhombic, the alar rather quadrate- 

 rectangular and not very distinct, the upper conflate, small, very 

 chlorophyllose, the inner median sublinear, the other oblong-lanceolate ; 

 costa thick and subflexuous, long and vanishing near the acumen. 

 Branch-leaves ovate-oblong, more distinctly revolute at the borders,
