Stems relatively pubescent at nodes, usually more than 15 hairs per 0.1 sq. mm at most pubescent portion (excluding angle of petiole with stem). Leaf blades 10 cm or more usually having at least 5 lobes; smaller blades (ca. 5 cm) usually with more than 3 easily visible veins branching off midrib (excluding proximal branches); surfaces usually more than 20 hairs per cm on length of midrib, more than 25 glands per 10 sq. mm between veins, abaxial glands in exceptionally dense concentration.
