Small, compact fern. |
| Foliage |
Pinnate fronds are arranged in a rosette. Each frond is composed of 20-30 pairs of leaflets known as pinnae (4 cm long, 1 cm wide). The pinnae form a triangular lamina that is 20-40 cm long and 4-8 cm wide. |
| Reproductive Parts - non-flowering plant |
Spores are produced by clusters of sporangia known as a sorus. The sorus is linear and covered by a protective flap of tissue known as an indusium which is 0.7 mm wide. The sori are arranged in 2 files on either side of the pinnae midrib. |
| Habitat |
It is found near forest streams at the base of trees and shrubs or on rocks. Locally, it can be found in the Bukit Timah Nature Reserve. |
| Etymology |
Genus Asplenium means without spleen and is usually a reference for the fern to cure spleen ailments. Species tenerum means soft, delicate and tender and refers to the characteristic of the fern. |
