|discussion=<p>Collections of subsp. drummondii at inland localities in Bexar and Dallas counties, Texas, and Henderson County, North Carolina, presumably represent introductions; it is also widely naturalized and is known from Africa, Asia, Australia, southwestern Europe, South America, and Taiwan (W. Dietrich and W. L. Wagner 1988; Wagner et al. 2007).</p>
