Discussion

Corchorus tridens is included for New Jersey and Pennsylvania based on documentation posted on the PLANTS website. No information is available on the abundance, but presumably it is rare or a waif, as other accounts do not include the species as naturalized in the flora area.

Selected References

None.

Lower Taxa

None.

"prolonged" is not a number."dm" is not declared as a valid unit of measurement for this property.
