Kosteletzkya (pronounced Kost-el-lets-kee-uh) ) is a genus of the plant family Malvaceae that includes the seashore mallow (K. virginica). It includes about 30 species found worldwide.Although similar in appearance to Hibiscus, Kosteletzkya typically bears more flattened capsules that dehisce loculicidally. The genus was separated from Hibiscus in 1835 by Carl Borivoj Presl, who named it after Vincenz Franz Kosteletzky (1801-1887).
