NATURAL HISTORY OF PLANTS. 



and superior ; it is composed of a unilocular ovary, surmounted by a 

 style swollen at apex, and covered with stigmatic papilla?. In the 

 ovary three parietal placentas are seen, the two posterior each 

 bearing- an indefinite number of ascending anatropous ovules, with 

 interior and inferior micropyle. 1 The fruit is a capsule, whose dehis- 

 cence is only according to the midrib of the placentas ; so that the 

 three valves of the fruit, superposed to the sepals 1, 2, and 3, bear 

 the seeds on their edges. Their coats cover a fleshy albumen enve- 

 loping an axile embiyo with cylindrical radicle, longer than the 

 cotyledons. 



Some dozen species 2 of Sauvagesia are admitted. They are gla- 

 brous herbs, sometimes suffrutescent at the base. The leaves are 

 alternate, simple, entire or serrulate upon the edges, accompanied 

 by two lateral, pectinate-ciliate stipules. The elegant flowers 3 are 

 axillary and solitary, or collected in terminal racemes. All are 

 natives of the warm parts of America ; S. erecta, however, is also 

 found in all the tropical regions of the Old World. 



Beside Sauvagesia are placed two very analogous types from the 

 Indian Archipelago, which perhaps ought not to be generically 



Lavradia glandulosa.

 stamens, each represented by a linear or subulate filament, scarcely 

 larger than the numerous tongues of the disk, which they resemble 

 a little in form ; and Neckia, which, besides the tongues, has a
