PELTANDRA VIRGINICA (L.) SCHOTT (ARACEAE).—Whatcom Co., about 8 km west of Ferndale on the westshore of Lake Terrell, 48u51.7489N 122u41.9439W,elevation 65 m. Growing on shore in shallow waterto about 20 cm deep, associated with Typha latifoliaL., with dense Phalaris arundinacea L. higher onthe shore. 12 July 2007, A. Fullerton and S. Boothe(WTU).

Previous knowledge. Peltandra virginica is native tothe eastern United States and southeast Canada and ismost common on the Atlantic Coastal Plain. Its rangehas expanded to the Midwestern states over the last30 yr. Introduced populations are recorded in Califor-nia and Oregon as far north as the south shore of theColumbia River in Clatsop County (S. A. Thompson,Araceae, pp. 128–142 in Flora of North AmericaEditorial Committee, Flora of North America Northof Mexico, vol. 22, 2000; WTU Herbarium on-linedatabase www.washington.edu/burkemuseum/collections/herbarium/index.php accessed 6 February 2008).

Significance. This is the first record for WashingtonState. The small population is located on the undevel-

oped shore of Terrell Lake, a Wildlife Area managed bythe Washington Department of Fish and Wildlife.Peltandra virginica is available in the horticulture trade,however due to the remote nature of the site we feel thispopulation more likely grew from seed transported bywaterfowl from locations where the plant persists inOregon or California.

HIBISCUS MOSCHEUTOS L. (MALVACEAE).—Doug-las Co., 1 km northwest of the town of Rock Island onthe northeast shore of Big Bow Lake, 47u23.089N120u9.299W 19, elevation 201 m. Several plants growingin shallow water and just above the waterline along theeast end of the lake; associated with Schoenoplectusacutus (Muhl. ex Bigelow) A. & D. Love, Typha latifoliaL., and Phalaris arundinacea L. September 2005, J.Parsons (WTU).

Previous knowledge. The native range of Hibiscusmoscheutos includes Ontario, Canada, the easternUnited States east of the Mississippi River and acrossthe southern states to New Mexico (United StatesDepartment of Agriculture PLANTS database, ac-cessed February 7, 2008 www.plants.usda.gov).

Significance. This is the first record for WashingtonState. Hibiscus moscheutos is widely available in thehorticulture trade. This population is likely an escapedgarden ornamental. The population has been observedfor four years and appears to be persisting andexpanding slowly among other native an introducedshoreline species.
