LATIN AND GREEK NUMERALS. — ARTIFICIAL CLASSES AND ORDERS. 
We shall now present you with a list of Latin and Greek numer- 
als ; these it is necessary to commit to memory, in order that you 
may understand the names given to the classes and orders. It is not 
in Botany alone that a knowledge of these numerals will be useful to 
you ; many words in our common language are compounded with 
them ; as, uniform, from umis, one, and forma, form ; — octagon^ from 
ocio, eight, and gonia, an angle, hexagon, pentagon, ^c.

The Classes of Linnccus. 
In the first place, all plants are arranged in two grand divisions, 
Phenogamous, when the stamens and pistils are visible, and Crypio- 
gamous, when the stamens and pistils are too small to be visible, by 
the naked eye. The former division includes 20 classes, the latter 
onl)'" the 21st. 
The classes are founded upon distinctions observed in the Sta- 
mens. All known plants are divided into twenty-one classes. 
The first twelve classes are named by prefixing Greek numerals 
to ANDRiA, which signifies stamen.
