Genera, are characterized by the analogy of all the parts of the flower
or fructification. The Species are distinguished by the foliage of the
plant; and the Varieties by any accidental circumstance of colour, taste,
or odour; the seeds of these do not always produce plants similar to the
parent; as in our numerous fruit-trees and garden flowers; which are
propagated by grafts or layers.

The first eleven Classes include the plants, in whose flowers both the
sexes reside; and in which the Males or Stamens are neither united, nor
unequal in height when at maturity; and are therefore distinguished from
each other simply by the number of males in each flower, as is seen in
the annexed PLATE, copied from the Dictionaire Botanique of M. BULLIARD,
in which the numbers of each division refer to the Botanic Classes.

CLASS I. ONE MALE, _Monandria_; includes the plants which possess but One
Stamen in each flower.

II. TWO MALES, _Diandria_. Two Stamens.

III. THREE MALES, _Triandria_. Three Stamens.

IV. FOUR MALES, _Tetrandria_. Four Stamens.

V. FIVE MALES, _Pentandria_. Five Stamens.

VI. SIX MALES, _Hexandria_. Six Stamens.

VII. SEVEN MALES, _Heptandria_. Seven Stamens.

VIII. EIGHT MALES, _Octandria_. Eight Stamens.
