1. Actinidia arisanensis Hayata 阿里山獼猴桃
Tall climbing shrub to 5 m or more; branches dimorphic, the spring shoots glabrous to densely strigose, with narrower glabrous or sparsely setose or densely strigose leaves, the summer shoots flowering, strigose to glabrous, with generally broader nearly glabrous leaves; pith very small, brown, lamellate. Leaves chartaceous, ovate-oblong to ovate, 8-15 cm long, 3-9 cm broad, acute to acuminate, cuneate-rounded to subcordate at base, usually unequal, sparsely and finely denticulate, glabrous or strigose on both surfaces, the dary veins 5-7 per side; petioles slender, 1.5-4.5 cm long, strigose or glabrous. Inflorescences in axillary cymes, 3- or 4-flowered, the pedicels nearly glabrous, 5-10 mm long; bracts minute; flowers white; sepals 5, oblong, rounded at apex, about 4 mm long and 2 mm broad; petals 5, oblong-ovate to oblong-lanceolate, about 7 mm long and 3 mm broad, rounded at apex, cuneate and contracted at base; ovary subglobose, densely tomentose; styles about 4 mm long. Fruit subglobose, about 2.3-3.5 cm across, glabrate, lenticellate. Endemic. In thickets and forests at altitudes of 1,160-2,260 m.

This is a very variable plant, with dimorphic spring vegetative and summer flowering shoots. The young sterile shoots may be strigose, bearing densely strigose leaves, or with nearly glabrous stems and leaves sparsely strigose above only, or with nearly glabrous leaves. The flowering shoots bear larger broader leaves, generally strigose all over the upper surface.
