Question

Which of the following is called the walking fern?
A) Selaginella
B) Adiantum
C) Equisetum
D) Psilotum

Answer 1

Hint: Walking ferns are tough plants that thrive in the shady areas of limestone ledges and limey wooded areas. The common name comes from the fact that new plantlets sprout wherever the tips of the parent plant's arching leaves make contact with the ground.

Complete Answer:
Walking fern refers to two species of fern in the genus Asplenium that are sometimes placed in a separate genus Camptosorus. The term "walking fern" refers to the fact that new plantlets grow wherever the parent's arching leaves touch the ground, creating a walking effect.
Both have evergreen, undivided, slightly leathery triangular leaves that taper to a thin point. Sori, or spore-bearing structures, cluster along the veins at the base of the leaves.
Asplenium rhizophyllum (also known as Camptosorus rhizophyllum) is a plant native to North America.
Asplenium ruprechtii (Camptosorus sibiricus), a species native to East Asia.
It could also refer to:
Adiantum caudatum is a type of maidenhair fern.
Adiantum is a member of the Polypodiaceae family. It is a sporophytic plant with roots, stems, and leaves as its plant body. They are frequently found in warm climates. The plant prefers moist, shady environments. These are evergreen plants with leathery-looking leaves. The leaves are triangular in shape and taper to a point.
Because the plant is homosporous, reproduction occurs through the production of spores in sporangia. The spore-bearing structures, known as sori, are found at the base of the leaves, along the veins. The petioles of the leaves are brittle and shiny black in colour. Thus, new plantlets form through vegetative reproduction whenever the parent plant's arching leaves make contact with the ground, resulting in a walking effect. As a result, Adiantum is also known as the "walking fern".

Therefore , the correct Answer is option (B) Adiantum.

Note:
Adiantum is also known as "maidenhair fern." It is grown for ornamental purposes. It is found in south-east Asian countries such as India, Thailand, the Philippines, China, Nepal, Burma, and Bangladesh. These plants are delicate in appearance, resembling a drooping fern. Its leaf segments are fan-shaped and found in clusters on the wire like black stems.
