Question

What do you mean by ligulate?​

Answer 1

Furnished with ligules, ligulae, or ligulate corollas : shaped like a strap ligulate corolla of a ray flower.

A ligule (from Latin: ligula "strap", variant of lingula, from lingua "tongue") is a thin outgrowth at the junction of leaf and leafstalk of many grasses (Poaceae) and sedges. A ligule is also a strap-shaped extension of the corolla, such as that of a ray floret in plants in the daisy family Asteraceae.
