with another and with the plant, in all probability little 
difficulty will arise. 
Supposing, for instance, the class is found to be Jcosan- 
dria, 11 consequence of there being twenty or more stamens 
fixed to the calyx, and the order Monogynia, because there 
is but one pistil, then the plant will be found to be Prunus, 
apd the species spinosa, as that is the only specimen of that 
class in flower at that early season. If the Natural System 
is preferred, apply for the class, subclass, and order, to 
the table, beginning at page 20, and supposing the plant to 
be in the class Hxogens, subclass Calyciflore, order Rosacea, 
refer to that order in March (of which there are only two 
examples), and the plant will be found to be the Prunus 
spinosa, as above; so that whichever system js pursued, 
the result will be the same. The generic and specific dis- 
tinctions are very similar in both systems. If the name 
should fail to be found, either a great mistake has been 
made, and a re-examination must take place, or the plant 
may be mentioned in the next month, or it is a more rare 
species than so small a work admits.* It should not, how- 
* To good botanists this work will appear imperfect, as not containing all 
the plants they are acquained with ; but to a young beginner it is better only 
to have what may be termed a vocabulary of the principal plants likely to 
strike the eye on first commencing the study. Nearly 600 species are 
described.
