The seeds of Ungnadia have a sweet rather pleasant flavor, but possess powerful emetic properties 
and are reputed to be poisonous. 
Ungnadia was discovered in western Texas by Thomas Drummond. It was named in honor of the 
Baron Ferdinand von Ungnad, ambassador of the Emperor Rudolph II. at the Ottoman Porte, who in 
1576 sent seeds of the Horse-chestnut tree from Constantinople to Clusius at Vienna. It is repre- 
sented by a single species.
