OBSERVATIONS ON THE CLASSES AND 
ORDERS. 
The immortal SEXUAL SYSTEM of Linn^us, 
whose transcendent merits soon made it triumphant 
over every other system, is founded upon the beautiful 
doctrine of the SEXES of plants. According to this 
system all known plants are distributed into different 
CLASSES, ORDERS, GENERA, and SPECIES. The 
CLASSES are twenty-four, and are derived from the 
consideration of 1- The number. 2. The number 
and oitiGiN. 3. The number and proportion. 4. 
The UNION. 5.'The SEPARATION^ and 6thly, The 
Concealment of the 'Stamina, 
1. Classes derived from the consideration of the 
Number of Stamina, 
The names of the first elemn classes are derived from 
the Greek words an^, aner, a male, av^pof, andros, 
the genitive case, and some Greek word prefixed imply- 
iog number^ as -

Class IL Diandria, from dis, txvo, and ccmq,
