--><p><i>Kallstroemia</i> is the largest New World genus of the family. <i>Kallstroemia</i> pubescens (D. Don) Dandy, native to the Caribbean, was collected in the United States at least six times in four states (Arizona, Florida, Georgia, and Texas) between 1833 and 1898, but apparently has not become naturalized. It most closely resembles <i>K. hirsutissima</i> and <i>K. maxima</i>, and is to be expected in sandy, coastal areas from Georgia to Florida and along the Gulf Coast to Texas. <i>Kallstroemia</i> pubescens can be distinguished from <i>K. hirsutissima</i> by having leaflets that are appressed-hairy to glabrate (versus densely hirsute) and sepals that are lanceolate and spreading in fruit with sharply involute margins (versus subulate, clasping the fruit, and with only the scarious margins involute). It can be distinguished from <i>K. maxima</i> by having ovaries and fruits that are densely hairy (versus glabrous or sometimes basally strigose) and styles that are densely short-pilose at the base (versus glabrous).</p>
