Margins plane or involute near the apex and entire (rarely serrulate at base). Costa absent or short and either single or double.

Leaf Cells: Cell walls thick and sometimes pitted near base. Median cells 34-86 x 6-8 µm. Alar cells differentiated, enlarged, and inflated, rectangular to rounded, cell walls pitted, and 16-56 x 16-26 µm.
