Hexastylis or heartleaf is a segregate of the genus Asarum, in the family Aristolochiaceae. The group comprises ten species endemic to southeastern North America. It is a perennial, evergreen, herbaceous plant with leaves and flowers arising directly from the rhizomes. Hexastylis was once recognized at the level of genus, and in some floral treatments still is, yet it has been shown through morphological and molecular evidence that it is rooted within the genus Asarum.[1]
