CLASS XIII. POLYANDRIA. 
(many stamina or males.) 
The flowers of this class are furnished with many stamina, 
(above twenty) inserted into the common receptacle. From 
this invariable character, is this class distinguished from the 
preceding class, icoscindria; which is very necessary to ob¬ 
serve, as the fruits of this class are frequently poisonous. 
This class contains eight orders.
