Taxonomic notes
Synonyms: Persicaria punctata (Elliott) Small var. punctata; Polygonum punctatum Elliott; Polygonum punctatum Elliott var. punctatum; Persicaria punctata (Elliott) Small var. leptostachya (Meisner) Small; Polygonum punctatum Elliott var. leptostachyum (Meisner) Small; Polygonum punctatum var. parvum Marie-Victorin & Rousseau; Polygonum punctatum Elliott var. confertiflorum (Meisner) Fassett.[1]
The species name "punctata" is derived from Latin, meaning dotted. This refers to the dotted glands of the flowers.[2]
Description
A description of Persicaria punctata is provided in The Flora of North America. The Radford Flora describes it as an "annual or rhizomatous perennial with erect, terete, glabrous or short-strigose stems. Leaves are glabrous to short-strigose, 6-15 cm long, 1-3 cm wide, tapered to petioles 2-20 mm long; ocreae strigose, 1-2 cm long, cilia 1-8 mm long. Racemes straight or arching, densely to very loosely flowered. Calyx white or greenish, rarely tinged with red or pink, conspicuously glandular-punctate. Nutlets black, glossy, trigonous or biconvex, 2.5-3 mm long."[3]
Distribution
P. punctata is found throughout most of the United States, ranging from Novia Scotia, Ontario, and British Columbia, south to Florida, Texas, and California, and even extending into the New World Tropics.[1] It is introduced instead of being native in Idaho, Montana, Colorado, Utah, Wyoming, and Hawaii.[4]
Ecology
Habitat
P. punctata is found in wet areas such as floodplain forests, swamps, seeps, pond shores, and drainage ditches.[5] In the Coastal Plain in Florida, P. punctata has been found in wet margins of wax myrtle thickets.[6] It prefers full to partial sun in mucky soil rich in organic matter and will tolerate shallow standing water.[5]
Phenology
This species flowers July through November[1]
Seed dispersal
The seeds are not adapted for dispersal other than floating in water, however, it is postulated to be transported by mud on the feet of water birds.[7]
Herbivory and toxicology
Persicaria punctata has been observed to host plant bugs from the Miridae family such as Lygus lineolaris.[8] The seeds are eaten by ducks and various songbirds.[5]
Conservation, cultivation, and restoration
Cultural use
Historically, the Chippewa used the leaves and flowers to treat stomach pain, and the Houma used roots to treat joint pain.[9]
