The leaf blades are 6 to 12 cm long, 3 to 8 cm wide, triangular, arrow-shaped, ovate-heart-shaped or long, pointed. The lateral leaf lobes are protruding and somewhat pointed. Both leaf surfaces are hairless to sparsely or densely hairy silky.

The inflorescences are usually longer than the surrounding leaves. They are mostly compact, little to ten-flowered cymes with an inflorescence stalk up to 10 cm long. The flower stalks are accompanied by bracts , are slender and up to 1 cm long.
