76. ORCHID ACEiE. ( ORCHIS FAMILY.) 



A vast family of mostly herbaceous plants, although some in 

 the tropics are shrubs. Many of the orchids are epiphytes; 

 plants growing on living or dead trees, but drawing sustenance 

 from the air. They are natives of all parts of the world, but 

 most numerous in the tropical forests of America, and are re- 

 markable for the extreme beauty and odd structure of their 

 flowers, as well as for the grotesque character of the stems and 

 roots of many species. The root tubercles of a few species fur- 

 nish the ingredients of a nutritious article of food. Vanilla is 

 a product of a climbing shrub belonging to the order. Only a 

 few species grow in the United States.
