Thorns single, double, and triple, directed downward along the entire length of the shoots. Thorn thickness medium, length 7–11 mm. Thorns present in the lower part of the shoots. Buds small, elongated, brown, with pointed, light tips, no hairs. Bud placement on the shoot opposite. Terminal bud single. Position relative to the shoot pressed.

Leaf medium-sized, green, with weak gloss. Young leaves hairy. Leaf surface moderately wrinkled, blade grass-like. Leaf blade slightly concave. Leaf margins large, tooth tips straight. Main vein color green. Three-lobed. Central lobe pointed, equal in length to lateral lobes. Central lobe edges trimmed straight to the base. Lateral lobes 3 cm long, 2 cm wide. Vein angles acute. Basal lobes present, with veins directed toward the base. Leaf base broad and straight. Cut between central and lateral lobes acute. Basal lobes moderately developed. Petiole notch rounded.
