Description
 
 

All of the mature leaves are very deeply lobed, all the way to the midrib, for the entire blade length. The terminal lobe is no larger than the lateral lobes. Early leaves may be shallowly lobed, but these leaves become more deeply lobed as they mature.

The flower heads are up to 1 in diameter.

The cypsela is brick red to reddish-brown or reddish-purple.

Similar Species

 
 

Common dandelion (Taraxacum officinale ssp. officinale) early leaves tend to be much less deeply cut. One or more leaves may be deeply lobed while remaining are less so. The lobes tend to be broader. The flowers tend to be larger, up to 2 wide. However, all of these characteristics overlap, making vegetative identification difficult. The most reliable identification feature is the color of the cypsela: olive green, olive-brown, or straw-colored, never reddish.

Glossary

Cypsela

A dry, one-chambered, single-seeded seed capsule, formed from a single carpel, with the seed attached to the membranous outer layer (wall) only by the seed stalk; the wall, formed from the wall of the inferior ovary and also from other tissues derived from the receptacle or hypanthium, does not split open at maturity, but relies on decay or predation to release the contents.
