The adaxial outgrowth from the base of the leaves in Selaginella is known as (B) ligule. It resembles the shape of a finger. A ligule has basal hemispherical glossopodium and is enclosed with glossopodial sheath. A combination of large and small cells, over the glossopodium, makes the body of ligule.
