METHOD OF ANALYSIS. 
ical Journey, and the plant being his Directory ; if he can read ths 
botanical characters impressed on it by the hand of Nature, he will, 
by following system, soon arrive at his journey's end.* 
Let us suppose, then, we have before us a plant in blossom, of 
whose 7iame and propeTties we are ignorant. — The name must be 
first ascertained, and this can only be done with certainty by the 
Linnaean system. 
In the first place we have ttoo comparisons to make. 
1st. Whether the Stamens and Pistils are visible. 
2d. Whether they are invisible. 
If the Stamens and Pistils are not visible, we have already arrived 
at the class, which is Cryptogamia. 
If, however, the Stamens and Pistils are visible, we have now two 
comparisons to make. 
1st. Whether the flowers have stamens and pistils on the same co- 
rolla. 
2d. Whether the Stamens and Pistils are placed on different co- 
rollas. 
If the Stamens and Pistils are on different flowers, we then shall 
find our plant either in the class DicBcia or Moncecia ; 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 enclosed in the 
same corolla, we must next examine, 
1st. Whether the Anthers are separate, or, 
2d. Whether the Anthers are united. 
If we find j^t^e 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 filaraents are separate, or, 
2d. Whether the filaments are united ^sr'ith each other, or, 
3d. Whether the Jilam,ents 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 filaments united to the pistil, we must as- 
certain 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, buty 
If in one parcel or set, it is in the class Monadelphia. 
But if the filaments are separate, we must next examine, 
1st. Whether these are similar in length, or, 
2d. Whether they are of different lengths. 
(Of different lengths, those only which have/bwr or six stamens are 
to be regarded.) 
If we find our flower ha,s six stamens, fiour 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,

What two comparisons to be first made in analyzing a plant — When the stamens 
and pistils are enclosed in the same corolla, what is next to be considered When 
the anthers are separate, what must be done ? — If the filaments are separate, what 
must be observed'?— If the flower has not stamens of unequal length, what is to be 
observed 1
