Florida Tickseed
Coreopsis leavenworthii

Asteraceae (Composite Sunflower) Family

 
.

Plant is an upright, smooth annual; branching at the base and spreading. Preferred habitat is fresh and brackish marshland, wet ditches and depressions. Distribution is coastal in the Escambia region.

Leaves are alternate on the stem; deeply dissected or subdivided into trifoliate-like segments. The segments are toothed and lobed; leaf stalks. The segments are narrowly linear to lance-like or oblong and widest at the middle; often irregular in form; upper stem leaves may be simple, lance-like with smooth margins or slightly toothed.

Flowers are solitary on long stalks; symmetrical in form. Disc flowers are bisexual and yellow. Ray flowers are female and yellow; three to four-lobed and often overlapping (rotate). Pappus is minute or absent. Flowering season is late summer extending into autumn. A related species, B. coronata, is identical except its leaves are smaller and it flowers earlier in the year.

Fruit is a seed which outer layer is fused to it (achene).

This plant is easily distinguished from most other tickseed because of its large, deeply dissected leaf and the outer flower bracts are smooth
