CLASS I. 
MONANDRIA. 
Containing flowers with 1 Stamen only. 
Tur flowers arranged under this class contain only one 
stamen. It might be supposed, that flowers containing 
only one stamen, and one, or at most, two pistils, must, 
from the simplicity of their structure, be easy to investi- 
gate; and undoubtedly they would be so, were it not for 
the minuteness of their parts. It fortunately happens, 
however, that the inexperienced botanist is not likely to 
encounter them at the commencement of his progress; the 
Salicornia is only found on the sea coast; the Hipputis 
is not very common ; the Zanichellia and Chara are less 
rare, ses the Callitriche is frequent enough in watery 
ditches and very slow streams, but neither of them ale | 
likely to attract attention, until a habit of accurate obser- 
vation has been formed. The Aphanes, the only ——- | 
Genus, may occasion some difficulty from ifs want 
agreement with the Generic description ; but the observa- 
tions subjoined to that description will obviate every pos 
sible doubt.
