COMPARISONS: Annularia latifolia possesses shorter, oblanceolate
leaves, with maximum width in the upper third; it has a smaller length/breadth ratio than Annularia fertilis.

Lakeside daisy (Tetraneuris herbacea Greene) is an herbaceous, thick-rooted, spring-blooming, polycarpic perennial herb in the family Asteraceae characterized by a short, fibrous-rooted caudex; tufted, oblanceolate
, puncate, basal leaves, 1-8 cm long and 2-10 mm wide, and a solitary head terminating a scape up to 25 cm in length (Wunderlin 1971, Gleason and Cronquist 1991).
The plant is about 1 m high with oblanceolate
green leaves, dentate at the top and marked with resinous points.
Leaves are narrowly elliptical to oblanceolate
and acute and have entire to slightly toothed margins.
However, there are many differences among species in the following characters: rhizome habit (long-creeping or compact, horizontal or ascending); rhizome scales (3-25 mm long; deltate to linear; margins entire, dentate, or ciliate; concolorous or bicolorous; gold to black); blade scales (entire or stellate; round or ovate; gold or black; abundant, scarce, or absent); frond size (10-100 cm); blade base (attenuate, cuneate, or obtuse); blade apex (acuminate, acute, of rounded); and blade shape (elliptic, oblanceolate
, oblong, linear-lanceolate, etc.
