Encyclopedia
Crepis runcinata is a species of flowering plant in the daisy family
known by the common name fiddleleaf hawksbeard. It is native to western and central North America, where it grows in many types of habitat. It is a variable species with many subspecies. In general it is a perennial herb growing an erect, hairless, mostly leafless, unbranching stem up to about 80 centimeters tall from a taproot
. The hairless leaves are arranged about the base of the plant in a rosette, each somewhat narrowly oval in shape with many toothlike triangular lobes or sometimes lacking lobes. The inflorescence
produces flower heads
with hairy, glandular phyllaries
and many yellow ray florets. The fruit is a small achene
with a pappus
