Persicaria virginiana

Summary ⁴

Jumpseed (Persicaria virginiana) is a Persicaria. They can grow in dry, shady areas.

Comments ⁵

Tension in the articulation of the pedicels is sufficient to throw mature achenes 3-4 m when the inflorescence is bumped, and the persistent, hooked styles aid in the dispersal of achenes in the fur of animals (H. S. Reed and I. Smoot 1906). A hot infusion of leaves with bark of honey-locust (Gleditsia triacanthos Linnaeus) was used by the Cherokee to treat whooping cough (D. E. Moerman 1998).

Evolution ⁶

Persicaria virginiana has been included in two molecular phylogenetic analyses (Kim and Donoghue 2008 and Lamb Frye and Kron 2003). Its sister species is P. filiformis and both of these fall out as a sister grouping to the Eupersicaria (Kim and Donoghue 2008). P. virginiana can be distinguished from P. filiformis, and P. neofiliforme by its specific flavonoid chemistry (Mun and Park 1995).
