Linnaeus ([1753] 1957) called these climbers Vinca<br />
lutea. Then, for many decades, they were called<br />
Urechites lutea, a genus established in 1860 by the<br />
Swiss botanist Johannes Müller of Aargau. However,<br />
Bruce Hansen realized that Pentalinon, described from<br />
plants grown in the Calcutta Botanical Garden in<br />
1845, was an earlier and valid generic name (Hansen<br />
and Wunderlin 1986). Pentalinon now contains two<br />
species, both native to Florida, Central America, and<br />
the Caribbean.<br />
In the Dominican Republic Pentalinon is used to<br />
treat heart disease (cardiotonic), edema, fever, and<br />
colic, and as a purgative (Hocking 1997). Plants are<br />
used to treat headache in Guatemala (Rosatti 1989).<br />
However, doing so is dangerous because the latex is<br />
poisonous, having been used to poison arrows in<br />
tropical countries (Rosatti 1989). It is poisonous to<br />
cattle; people powder the leaves to kill destructive<br />
insects and animals (ants, dogs) (Liogier 1974).<br />
Among the poisonous compounds are the cardenolides<br />
oleandrin, urechitin, and urechitoxin (Gibbs<br />
1974).<br />
