118 Didynamia , 
Crescentia.. Gen. char . — Berry one-eelled, with 
a hard, woody covering; cor. with tube; bell-shaped 
germen, supported on a foot-stalk. 
Cres. Cujete , Narrow-leaved Calabash, with wedge- 
shaped lanceolate leaves. Native of Jamaica ; a tree 
which rises to the height of twenty feet, and is remark- 
able for the large size of its fruit, which is sometimes 
afoot in diameter; and the hard, woody shell is employ- 
ed by the negroes as bottles, cups, spoons, and other 
kitchen utensils. Another species is a native of Jamai- 
ca ; but the shell of the fruit is so thin that it cannot 
be applied to the same purposes. 
Melianthus. Gen. char. — -Cal. five-leaved, with- 
the inferior leaf gibbous ; petals four, with the nectary 
beneath the lowest ; caps, four-celled. 
Two species of this genus have been described, 
Major and Minor, both of which are cultivated in this 
country, and are remarkable for the copious secretion of 
honey, which is so abundant in the former as to drop 
from the flowers. 
CLASS XV. 
TETR ADYNAMIA. 
In this class the character is derived from the une- 
qual length of the stamens, four of which are long and 
two short, standing opposite to each other. The flowers 
are composed of four petals, arranged two and two op- 
posite to each other, in the form of a cross, and hence 
are called cruciform flowers. This class is divided into 
two orders, characterised by the length of the pod.
