Rank ReasonsVirginia Three-seed-mercury (Acalypha virginica) occurs in the eastern United States, its native range is from Massachusetts to Georgia, Texas, and eastern Kansas. It is adventive in the northern part of its range, in the Great Lakes area, northern New England and Ontario, Canada where it is considered to be exotic. There are more than 300 occurrences within its native range, and threat impacts likely are low overall.
Range Extent CommentsVirginia Three-seed-mercury (Acalypha virginica) occurs in the eastern United States, its native range is from Massachusetts to Georgia, Texas, and eastern Kansas. It is adventive in the northern part of its range, in the Great Lakes area, northern New England and Ontario, Canada where it is considered to be exotic. The native range extent was estimated to be 2.2 million square kilometers, using herbarium specimens and photo-based observations documented between 1992 and 2023 (Flora of North America Editorial Committee 2016, GBIF 2023, iNaturalist 2023).
Occurrences CommentsBy applying a 1 km separation distance to herbarium records and photo-based observations documented between 1992 and 2023, it is estimated that there are more than 300 occurrences rangewide (GBIF 2023, iNaturalist 2023).
Threat Impact CommentsThreat impacts likely are low overall.
