well with the Leontodon, we fix upon that as the Genusi 
Now we look forward to the Generic description for further — 
information ; with this it perfectly agrees, and in the Onserva- 
TIONS subjoined, we are told that in the Leontodon Taraxacum 
the Down of the Seed is supported ona long pedicle, which 
we had already remarked in’ the flower batts us. We now 
_ read the characters of the different Species ; and, from the deep 
notches'in the leaves, judge our plant to be the. pureed 
Taraxacum, or common Dandelion. — rt 
It will be very proper for the learner thus to examine several 
more Genera of this Clafs, as the Coltsfoot, the Burdock, the 
Thistle, the Tansy, the Daisie, and the Groundsel ; for, by 
doing this, he will soon overcome the difficulties which. present 
themselyes; and when any of the books are at hand which are 
mentioned in Italic print, ‘after the Specific Character, it will 
be satisfactory to turn to them, and to geste the pe in 
question wth the figures referred to. 
It may'not be amifs for him to begin with a go 
which, though not an English plant, and therefore not to be 
found in this book, may yet, from the large size of its Florets _ 
enable him to form a good idea of the structure ee Compound 
Flowers in general. 
By paying a proper atterition to the ontape of Compound 
Flowers, we soon learn to distinguish them from double Flow- 
ers; and when by accident or cultivation any of the true 
Compound Flowers become double, we shall always find it

exclusion of others, : 
These examples will, it is ied afford sufficient instruc- 
tion to the learner, but, if he wishes for others, he may examine 
such plants as are mentioned in the Table of the Clafses. 
‘It still remains to say something of the Cryptogamia Clafs. 
The plants in that Clafs are not arranged like the other parts - 
former case, it is said to be hair-like: in the latter it is said to be feathered. ; 
Now as these circumstances must be attended to, in forming Generic 
Distinctions, it is necefsary to apprise the learner, that the Down must 
be exposed to the air a little time before he can pronounce whether it be 
hair-like, or feathered ; for whilst it is moist in the gos 8: the lateral 
hairs often lie 90 close as not to be visible, ee
