11. MALVAVISCTJS, Dill. 



Carpids 5, combined into a baccate pericarp : style 10-fid. Calyx surrounded by a 7-12- 

 leaved involucel. Petals convolute at the base, auriculate on one side. — Shrubs or trees, with 

 axillary pedicels ; leaves dotted. 



46. M, arbor eus, Cav. (exclus. synon. Dillen.). Leaves cordate, longer than broad, 

 crenate or subentire (sometimes obsoletely 3-lobed) ; involucel-leaves 7-9, linear ; column 

 twice as long as the red corolla; berry "yellow." — SI. t. 136./. 1.— Achania malvaviscus, 

 w.yl cannot find any specific character to separate the variable forms of the West Indian 

 species, from which M. mollis, DC, of Mexico (often confounded with the same), is distin- 

 guished by the leaves as broad as long, the column shortly exserted, and " the berry red." 

 Hibiscus Malvaviscus, L., is a mixture of both ; for Sloane's, P. Brown's and Plumier's 

 synonym belong to the former, those of Dilleuius and Plukenet to the latter species.
