This action, called circumnutation, has the real effect of securing and pulling the branches higher, thus enabling its leaves exposure to the sun for photosynthesis.

Leaflets are typically between 23 – 24 cm long, broadly ovate, cordate at their bases, rounded and obtuse at their apexes, and finely-toothed on their margins.

Smaller veins are barely noticeable on the leaf's upper (adaxial) surface, while being slightly prominent on the under (abaxial) side.

They are intricately downy with brown tomentum adaxially, and covered in somewhat long and straight, slightly stiff but weak, hairs abaxially.

[2] The flower buds of A. xizangensis emerge elliptic, with a rounded apex, and measure 2 to 2.5 mm in length, blooming in July.
