“ INTRODUCTION TO 
for the Anthers are in that state more distinct, ‘and’we may 
be certain that none of them have been lost, Havitig fixed 
upon the Clafs which we believe to be right, let us turn to the 
Introduction to that Clafs, in this volume, and if the perusal 
of this. gives us no reason to alter our opinion, we are pretty 
certain of being so far right. It is best not to trust to the 
examination of one flower only; for we sball sometimes find 
the number of Stamens to be really different, in different 
flowers upon the. same plant; but in that case the clafsic | 
character must be taken from the terminating flower. 
Second. Having. thus determined the Clafs, we must next 
refer to the beginning of that Clafs in the second or third 
volume, where we shall find the Synopsis of the Genera con- 
tained in that Clafs. Here also we must look of how 
many Orpers the Clafs consists ; and after observing the cir- 
cumstances by which the Orders are determined, we must 
compare these with the plant before us. If the Order we refer 
it to has any subdivisions, we shall soon perceive under which

; Third. ‘After eninparton the. Flowers with’ the Characters of 
the different Geer contained in the Order, or in | the par- 
ticular subdivision of the Order, we shall soon perceive with 
which of them it best corresponds. , We now turn back to the 
description of that Genus in this volume, and if the description 
agrees pretty exactly with our specimen in all the leading 
characters, we conclude that we are now certain of the Genus. 
Doubtful matters will sometimes arise ; but these are for the 
Most part made clear by observations subjoined to the generic 
descriptions. 
In consulting the generic deecsibliona: the learner is desired 
to pay particular attention to the structure of the Pistil, and 
especially to that of its Germen, when it begins to ripenintoa |

continuation of the species, they are lefs poe to variation
