In the 23d class the Orders are called Monvecia, 
Dioecia and Tricecia. The last class has the follow- 
ing Orders, Filices, Musci, Algae and Fungi, (§ 122). 
§ 141. 
From the aforegoing analysis it will be seen that 
the Linnzean system consists of an artificial and 
sexual arrangement, and that it does not answer the 
idea, we have given above, (§ 124), of a perfect 
system. But till such a one is found out, a system 
partly natural, partly artificial is the best; we must, 
however, as we cannot deny the usefulness of Lin- 
neeus’s system, point out its defects. 
Linnzeus endeavoured, from the number of the 
stamina, their various lengths, and different modes 
of connection, to unite a natural classification with 
an artificial one. Hence arose some faults, which 
would not have happened had he, at the same time, 
made use of the corolla as’ a character. For in- 
stance, in the fourteenth class are contained the la- 
biated and ringent flowers; but because Linnzus 
characterised it from the four stamina, two of which 
are shorter; there are some of these plants which 
must stand in the second class, and others in the 
fourth, though they properly belong to this class. 
In the same manner, all the papilionaceous flowers 
are referred to the seventeenth class; but the as- 
sumed character, vz. that the filaments are united 
into two sets, is not to be found in all these plants : 
Many haye the filaments united in one cylinder ;. an
