METHOD OF ANALYSIS. , 43 



But if our plant has the Stamens and Pistils both enclosed in 

 the same corolla, we must next examine, 

 i 1st. Whether the Anthers are separate, or, 



2nd. ^Whether the Anthers are united. 



If we find^rue anthers united around the pistil, we have found 

 the class of our plant ; it is SYNGENESIA. 



If the Anthers are separate, we must proceed to a. fourth stage, 

 and see, 



1st. Whether the filaments are separate, or, 



2nd. Whether the filaments are united with each other, or, 



3d. Whether the filnments are united to the pistil.. 



If the latter circumstance is ascertained, we need search no 

 farther ; our plant is in the class GYNANDRIA. 



If the flower has not the filamenjs united to the pistil, we 

 must ascertain if the filaments are united with each other ; if 

 they are so, and in two parcels or sets, the flower is in the class 



DlADELPHIA, but, 



If in one parcel or set, it is in the class MONADELPHIA. 



But if the filaments are separate, we must next examine, 



1st. iWhetherthese are similar in length, or, 



2nd. Whether they are of different lengths. 



(Of different lengths, those only which have four or six sta- 

 mens are to be regarded.) 



If we find our flower has six stamens, four long and two short, 

 we need go no farther, this is the class TETRADYNAMIA. 



If the flower has four stamens, two long, and two short, it is 

 in the class DYDYNAMIA. 



If, our flower comes under none of the foregoing heads, we 

 must then count the number of stamens; if these amount to 

 more than ten, we must then consider their insertion, as, 



1st. Whether inserted on the calyx or corolla, or, 



2nd. Whether inserted on the Receptacle. 



If we find the Stamens inserted on the Receptacle, the flow- 

 er is in the class POLYANDRIA ; but if on the Calyx or Corolla, it 

 is in ICOSANDRIA. 



If our flower has less than twenty stamens, with none of the 

 peculiarities above mentioned, of connexion, position, or length, 

 we have only to count the number of stamens in order to be 

 certain of the class ; if there are ten stamens, it is in DECAN- 

 DRIA; and so on through the nine remaining classes. This is 

 the true analytical process ; but when we put plants together to 



When the stamens and pistils are inclosed in the same corolla what is next to 

 be considered When the anthers are separate what must be observed If the 

 filaments are separate what must be observed ? If the flower has not stamens 

 of unequal length, what is to be observed ? When is the flower in one of the 

 first ten classes ? Difference between analysis and synthesis.
