Resembling or containing fescue grass; having the characteristics of fescue.
From Latin festuca (straw, stalk) + -ous (full of). The Latin word originally referred to a stalk or stem of grain, and the suffix -ous means 'full of' or 'characterized by.'
Fescue is one of the most important grasses in lawn care and agriculture, so festucous describes anything that looks like this humble but essential plant. It's a rare word that shows how scientists create adjectives to describe plant-like qualities without needing to say 'like fescue' every time.
