MONADELPHIA. 
Class XVI. 
Class XVL— MONADELPHIA. 
This class is distinctly characterized by the filaments being united together throughout the whole or a part 
of their length ; and for the most part consists of plants belonging to the natural orders of Malvaces and 
Geraniaceae. Of the former, the major part are of little moment, consisting, in a great measure, of weeds or 
worthless shrubs of various parts of the world. Among them, however, are some plants both of interest and 
ornament, especially £he beautiful Astrapjea, and the various species of Bombax and Hibiscus. The Gossy- 
pium, so important as producing the material of cotton, and the Adansonia or Baobab tree of Africa, remark- 
able for its immense size and use as an article of food, are found in this class. The Geranium, Camellia and 
Passion flower are also genera of much beauty ; the latter yielding the well known West Indian fruit called 
the Granadilla. The common Tamarind, with which this class commences, would more properly be placed in 
the next, and the succeeding genera of Patersonia, Tigridia, Ferraria, and Galaxia, are in every respect, ex- 
cept the union of their filaments, referable to the third class.
