Chaerophyllum tainturieri Hooker. Southern Chervil. Phen: Mar-Apr; Apr-May. Hab: Roadsides, disturbed areas, fields. Dist: MD west to NE, south to c. peninsular FL, TX, and AZ

Origin/Endemic status: Native

Taxonomy Comments: Var. tainturieri (with fruits glabrous) and var. dasycarpum (with fruits pubescent) are sometimes distinguished (see synonymy). They have largely overlapping distributions, and seem unlikely to warrant taxonomic status, but need additional study. C. texanum Coulter & Rose is reported as a native in the Nashville Basin of TN (Chester, Wofford, & Kral 1997); it is usually now included in C. tainturieri (var. tainturieri).
