 shortly cuspidate-acuminate entire or serrated chiefly towards the apex, 

 nearly sessile, the base obliquely cuneate ; 

 primary veins slender but straight and 

 parallel costuliform, forming with the 

 anastomosing veins four or five series of 

 areoles each with a free included veinlet, 

 but of which the lowest series .only is so-
