The taxonomic type for the genus is Polygonum aviculare.
The genus produces fruit of the nucule type. While WoRMS lists its habitat as marine, other records indicate occurrences in Mexico and Belice. Institutions including UACH, ENCB-IPN, ECOSUR, INECOL, and IIB-UV hold records related to this taxon. The genus has been documented in various sources, including the Brockhaus and Efron Encyclopedic Dictionary and Gujin Tushu Jicheng.
