ABSTRACT
Linnaeus ([1753] 1957) called these climbers Vinca lutea. Then, for many decades, they were called Urechites lutea, a genus established in 1860 by the Swiss botanist Johannes Mûller of Aargau. However, Bruce Hansen realized that Pentalinon, described from plants grown in the Calcutta Botanical Garden in 1845, was an earlier and valid generic name (Hansen and Wunderlin 1986). Pentalinon now contains two species, both native to Florida, Central America, and the Caribbean.
