Malvaceae A number of species, including "Hibiscus syriacus", "Hibiscus rosa-sinensis" and "Alcea rosea" are garden plants. Malvaceae Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao and durian. There are also some genera containing familiar ornamentals, such as "Alcea" (hollyhock), "Malva" (mallow) and "Lavatera" (tree mallow). The largest genera in terms of number of species include "Hibiscus" (300 species), "Sterculia" (250 species), "Dombeya" (250 species), "Pavonia" (200 species) and "Sida" (200 species). The circumscription of the Malvaceae is controversial. The traditional Malvaceae
Sarracenia rosea "Sarracenia rosea" f. "luteola". The species is native to the Gulf Coast of the Southeastern United States, and has been found from Mississippi to Georgia. However, the areas in which the plant occurs are being developed, so the species's habitat is threatened. However along with "Sarracenia psittacina", this species readily colonizes drainage ditches along highways throughout the gulf states providing a somewhat more sustainable albeit less natural habitat. "S. rosea" is appreciably more shade-tolerant than the other members of the genus. "Sarracenia rosea" was first identified by the American botanist Edgar T. Wherry as a "mutant" form of "S. purpurea"
