- Diagnosis
- Lamina under 4 cm wide, L/W over 4; crenations 3-4 mm wide by less than 1 mm tall; marginal reinforcement showing no variation in width along the
length of each crenation. Secondary veins thin relative to primary vein; superadjacent secondary vein usually equal in thickness to the subadjacent secondary vein at their point of junction, forming an acute angle. Orientation of tertiary venation typically transverse; tertiary veins nearly as thick as the secondary veins.
