sepals, five petals, and numerous long slender stamens borne in a ring. 
The fruit is also large, containing from two to four kidney-shaped 
nuts or seeds with a flavor somewhat resembling that of the Brazil nut; 
a superior quality of oil is extracted from them. Fig. 154 shows a flow-

Family Maregraviaceae. Marcgravia Family. Contains 5 genera 
and about 40 species, natives of tropical America. They are trees or 
shrubs, distinguished by the peculiar 
pitcher-like bracts which often subtend 
the flowers. In Marcgravia the flowers 
have the further peculiarity that the 
corolla is united in one piece (gamopeta-

celled, becoming capsular in fruit. ~

to the family. The genus consists of about 16 species of shrubs, con- 
fined in the wild state to India, China and Japan, but cultivated in 
many parts of the world. The flowers are large and handsome, and are 
succeeded by 3-valved capsules, two of which are shown in the illustra-

The process of drying the tea leaves is an elaborate one, and upon 
the methods employed depends the flavor of the final product. The
