PinmsyWrnua, Muhlenberg ; Virginia? Elliotl. — (J) Stem 12-18 indies 

 high, sparingly branched, clothed with while hairs toward the summit. 

 Leaves ovale, toothed, very obtuse at the base, nearly glabrous above, hairy 

 on the veins beneath : petioles an inch long. Flowers axillary, solitary : pe- 

 duncles 2-3 lines long. Bracteoles setaceous. Petals twice as long as the 

 calyx, yellow. Carpels hispid, collected into a depressed globular head, 

 EUioll. — .\ultall, who saw the plant here described in Elliott's herbarium, 

 considered it the Malope Matacoides. According to EUiott it is the Malva 

 Americana of Muhlenberg, but not of Willdcnow. We have not the means 

 of determining the genus of this plant, but believe it to be a species of Malva.
