|discussion=<p><i>Urena lobata</i> is a pantropical weed, probably native to the Old World Tropics. The species has been reported from East Baton Rouge and Saint Charles parishes in Louisiana and appears to be naturalized. In South Carolina it has been introduced to the southeastern part of the state in landscape plantings and is spreading to vacant lots and roadsides. It has also been collected relatively recently in Scott County, Tennessee, as a waif, and will likely be found elsewhere on occasion. <i>Urena lobata</i> is well established in peninsular Florida and common in some locations, and has been grown for its jutelike fiber in some regions.</p><!--
--><p>The similar <i>Urena</i> sinuata Linnaeus [<i>U. lobata</i> <i></i>var.<i> sinuata</i> (Linnaeus) Hochreutiner] is known in Mexico, the West Indies, and elsewhere in tropical America and may occasionally appear as a waif within the flora area. It was once collected in ballast at Mobile, Alabama. This species differs from <i>U. lobata</i> by its deeply, palmately five-parted leaves with broadly rounded sinuses, its smaller (4–5 mm) calyx, and its shorter (8–18 mm) petals. Transitions are found between U. sinuata and <i>U. lobata</i>, and they may not be specifically distinct. The fruits in both taxa readily adhere to clothing and the plants have become widely distributed as weeds.</p>
