The difference between stone reed and wawe

1. Difference of blades

The leaves of stone reed are leathery, lanceolate, oblong-lanceolate or linear-lanceolate, about 7-20 cm long, about 1.5-3 cm wide, gradually pointed at the apex, gradually narrowing at the base, with entire margins, green with fine dots on the upper side and light brown star-shaped hairs on the lower side. The petiole is long, about 6-15 cm.

The leaves of the wale are papery, linear-lanceolate or narrowly lanceolate, and the petioles are much shorter than the former, about 1-3 cm long.

2. Difference of sporangium

The sori of stone reed are oval in shape, each sori is separated by star-shaped hairs, and are light brown in color.

The sporangium of Vave is round and covered with round brown septa when young. They are close to each other and almost connected when mature.
