Leaf-scar rhomboidal, as long as broad, but often broader than 

 long; upper margin rounded, flattened, or notched, lower margin 

 rounded, sides generally convex with sharp lateral angles. Prints 

 three, placed slightly above the centre of the leaf-scar, the central 

 print transversely linear, generally concave, the two lateral oblique, 

 frequently lunate, embracing the central print ; above the leaf-scar 

 there is frequently a small circular print.
