CLASS XIII. 
POLYANDRIA. 
Tue flowers of this class have, as its title implies, many 
stamens, that is, from 20 to 1000 or more, so that it is 
unnecessary to attempt to count them, further than to be 
satisfied that they amount to 20 or upwards. The situation 
of the stamens, as standing UPON THE RECEPTACLE, is 
sufficient to’ distinguish it from the preceding class, in 
which they do not stand upon the receptacle, but either 
upon the sides of the Calyx or else upon the Petals. A 
regard to this circumstance will be a surer guide than an 
attention merely to the NUMBER of the stamens. - If the 
e does not at once determine the exact situation of the 
Tames, carefully and slowly pull off the petals and the 
segments of the calyx, if the stamens remain in their 
places they may then be considered as growing: upon the 
receptacle,
