Crataegus crus-galli Linnaeus var. crus-galli. Common name: Cockspur Hawthorn. Phenology: Apr-May; Sep-Oct. Habitat: Pastures, thickets, disturbed woodlands and forests, fencerows. Distribution: Ranges throughout the eastern US, except c. and s. peninsular FL, sometimes forming extensive colonies.

Origin/Endemic status: Native

Taxonomy Comments: C. crus-galli is variable in the size and shape of leaves and minor flower and fruit characters, this accounting for an extensive synonymy. Most earlier names in the synonymy were applied by Charles Sargent. Plants having 3 to 5 styles and as many pyrenes are alternatively placed under C. reverchonii Sargent, these also exhibiting a tendency to have smaller, suborbiculate leaves on terminal shoots. Typical forms of C. crus-galli tend to have 1-2 styles and pyrenes, and with a range of leaf shapes from narrowly oblanceolate to nearly suborbiculate.
