Alsophila andersonii

Alsophila andersonii, synonym Cyathea andersonii,[1] is a species of tree fern native to India, Bhutan and southern China, where it grows in moist valleys and montane forest at an altitude of 300โ€“1200 m. The trunk is erect and 6โ€“10 m tall. Fronds are bi- or tripinnate and 2โ€“3 m long. The entire plant is relatively dark in appearance; the rachis is flushed with dark purple and the stipe is dark, almost to the point of being black. Dark, lanceolate scales with pale fringes are sparsely scattered along the length of the stipe. Sori occur near the midvein of fertile pinnules and lack indusia.[2]
