METHOD OF ANALYSIS.

1st. Whether the flowers have Stamens and Pistils together. 
2nd. Whether the Stamens and Pistils are placed on differ- 
ent corollas. 
If the Stamens and Pistils are on different flowers, we then 
shall find our plant either in the class Diaecia, or Monaecia ; 
according as the Stamens and Pistils are on different flowers, 
proceeding from the same root, or from different roots. 
But if our plant has the Stamens and Pistils both inclosed in 
the same corolla , we must next examine, 
1st. Whether the Anthers are Separate or, 
2nd. Whether the Anthers are united. 
If we find jive anthers united around the pistil , we have found 
the class of our plant, it is Syncenesia. 
If the Anthers are separate, we must proceed to a fourth stage, 
and see, 
1st. Whether the f laments are separate, or, 
2nd. Whether the filaments are united with each other , or, 
3d. Whether the filaments are united with the pistil. 
If the latter circumstance is ascertained, we need search no 
farther, it is the class Gynandria. 
If the flower has not the filaments 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 Diadelphia. 
If in one parcel or set, it is in the class Monadelphia. 
But if the filaments are separate, we must next examine, 
1 st. Whether these 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 class 
is Polyandria; but if on the Calyx or Corolla, it is Icosandria. 
When the stamens and pistils are visible what comparison is to be made 
— 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 ob- 
served — If the filaments are separate what must be observed — If the flower 
has neither four or six stamens of unequal length, what is to be observed — 
When is the flower in one of the first ten classes. —
