Botanical Name
Conyza canadensis (L.) Cronq. var. pusilla (Nutt.) Cronq.
Common Name
Southern Horseweed
Erigeron canadensis L. var. pusillus (Nutt.) Boiv.; Erigeron pusillus Nutt., s.s.
Flora of Virginia Name/Status
Erigeron pusillus Nutt.
Incompletely mapped; varieties of Conyza canadensis were not often been recognized in older Virginia floristic studies. Moreover, this var. resembles, and often co-occurs with, C. canadensis var. canadensis, which makes it easy to overlook.
Fields, roadsides, clearings, dunes, and other open, weedy habitats. The distribution and status of var. pusilla are incompletely known; recent field and herbarium studies suggest that this taxon is widely overlooked and under-documented; it is probably frequent across the southern two-thirds of the Coastal Plain and Piedmont, less so in the southern mountains. However, additional work is needed to fully delineate its distribution in the state.
