Description

Agnorhiza ovata grows in many types of habitat, including forests, woodlands, and grassland. It is a perennial herb growing from a thick taproot and caudex unit. The hairy, glandular, sticky-textured stem grows a few centimeters tall to nearly half a meter in maximum height. The leaves have oval blades up to 20 centimeters long which are generally hairy or silky and glandular. The inflorescence is made up of one or more flower heads which may be tucked amongst the uppermost leaves. The head has lance-shaped leaflike phyllaries which may be up to 5 centimeters long. There are 5 to 8 yellow ray florets which measure about 1.5 centimeters in length, and many yellow disc florets in the center. The fruit is an achene about a centimeter long tipped with a short pappus.[5][6]
