the word, affords four cases, which are the founda- 

 tion of the four first orders of this class. 1st Order, 

 Polygamia aequalis, equal Polygamy, is when all the 

 florets are hermaphrodite. 2d Order, Polygamia su- 

 perfiua, superfluous polygamy, when some of the flo- 

 rets are hermaphrodite, and others female only ; for 

 in this case, as the fructification is perfected in the 

 hermaphrodites, the addition of the females is a super- 

 fluity. 3d Order, Polygamia jrustranea, frustrations 

 or ineffectual Polygamy, when some of the florets 

 are hermaphrodite, and others neuter ; for in this 

 case the addition of the neuters is of no assistance 

 to the fructification. 4th Order, Poli/garnia mces- 

 sarict) necessary polygamy, when some 01 tiie florets 

 are male, and the rest female ; for in this case there 

 being no hermaphrodites, the polygamy arising from 

 the com position of the florets of different sexes is ne- 

 cessary to perfect the fructification. 5th -Order, Pcly- 

 gawia segrt.gata. The title signifies to be separated, 

 the plants- of this order having partial cups growing 

 out of the common cal*-x which .surround and divide 

 the flosculi or florets, 6th Order, Monogawia: the 

 title signifies a single marriage, and is opposed to the 

 Polygamia of the four other orders; for in this, 

 though the antherae are united, which is the essential 

 character of the flowers of this class, the flower is 

 simple, and not compounded of many florets, as in 

 ths other orders. 



CLASS XX. GYNANDRFA The orders of this 

 class are founded on the number of stamina. The 

 titles have been already explained. 



CiAssXXI. MONOECIA. XX 11. DiotciA. These 

 two classes; whose flowers have no fixed character 

 but that of not being hermaphrodite, take in the cha- 

 racters of almost every other class j and- the orders 

 have accordingly been disposed under the- titles of 

 those classes, to which -their respective flowers would 

 have belonged^ if the stamina and pistiilum had been 

 under the same covers, As the explanation of. all these
