Question

Pteridophyte called as stag's horn fern is

• A. Azolla
• B. Platycerium
• C. Botryopteris
• D. Salvinia

Answer 1

Answer: (B)

Platycerium

Platycerium is commonly called as staghorn fern, due to unequally grown fronds. These plants make two types of fronds. The shield, or sterile fronds, wrap around the tree or rock on which the plant is growing. These shields usually form a basket, which collects debris, providing a medium for root growth, and aiding in moisture collection and retention. The fertile, or normal fronds, grow out from the bud, and the spores are borne on these. Some species make fertile fronds much like the antler of a deer. Others are nearly round, or wedge-shaped.

So, the correct answer is option B.
