Vitis shuttleworthii is a North American liana (woody vine) in the grape family commonly known as the calloose grape or bear grape (alternatively referred as calusa grape). The name refers to the group of Native American people that resided in southwest Florida, the Calusa. It is native to south and central Florida, with isolated populations in southern Alabama.[http://bonap.net/MapGallery/County/Vitis%20shuttleworthii.png Biota of North America Program 2014 county distribution map]

The species was first described in 1887 using the name Vitis coriacea.[https://www.biodiversitylibrary.org/page/32082335#page/379/mode/1up Planchon, Jules Émile in Candolle, Alphonse Louis Pierre Pyramus de & Candolle, Anne Casimir Pyramus de 1887. Monographiae Phanerogamarum 5(2): 345] description in Latin, commentary in French However, this name had already been used for an Asian plant,[https://www.biodiversitylibrary.org/page/652070#page/92/mode/1up Miquel, Friedrich Anton Wilhelm 1863. Annales Musei Botanici Lugduno-Batavi 1: 78] in Latin so it was necessary to coin another name of the American species, now called V. shuttleworthii.[https://www.biodiversitylibrary.org/page/29541935#page/155/mode/1up House, Homer Doliver. 1921.
