Taxonomic notes
The species name punctata is derived from Latin meaning dotted, this refers to the dotted glands of the flowers[1].
There are three varieties which include: Persicaria punctata var. robustior, P. punctata var. ecilliata, and P. punctata var. tacubayana[2].
Description
A description of Persicaria punctata is provided in The Flora of North America.
"Annuals or perennials with lanceolate to elliptic leaves. Leaf base cuneate; ocreae with or without cilia. Flowers in racemes arranged paniculately at the apices of stems and branches. Sepals not, or only slightly enlarged in fruit. Nutlets trigonous, biconvex or lenticular." - Radford et al 1964
"Annual or rhizomatous perennial with erect, terete, glabrous or short-strigose stems. Leaves 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." - Radford et al 1964
