persistent; it is ovoid, 6 to 12 cm. long, brown and rough; the flat seeds are 18 

 mm. long, the broad thin wing ovate, blunt, thick, wrinkled and brown. 



The wood is very hard and strong, close-grained, red, darkening with age ; its 

 specific gravity is about 0.73. It is very durable and of the highest value in cabi- 

 net work and interior finishing and is cultivated in the East Indies for its valuable 

 timber. 



The genus is a small tropical one of probably not over 3 species, 2 American 

 and I African. The name is in commemoration of Gerard von Swieten (1700- 

 1772), a noted physician and botanist of Leyden and Vienna. Our tree is the type 

 of the genus.
