Vitis shuttleworthii is a North American liana (woody vine) in the grape family commonly known as the caloosa grape (alternatively spelled calusa). It is native to south and central Florida, with isolated populations in southern Alabama.The species was first described in 1887 using the name Vitis coriacea. However, This name had already been used for an Asian plant, so it was necessary to coin another name of the American species, now called V. shuttleworthii.
