Lobes acute, gaps between lobes small, central lobe elongated, with additional projections. Side lobes acute, directed sideways, angle between their main veins obtuse. Basal lobes well developed, veins directed toward petiole. Leaf base with a notch formed by overlapping leaf margins. Teeth broad, short, with "tips". Petiole of medium length and thickness, without hairs, green, deviated at 45° angle.
