XXIII. POLYGAMY, _Polygamia_. Male and female flowers on one or more
plants, which have at the same time flowers of both sexes.


The last Class contains the plants whose flowers are not discernible.

XXIV. CLANDESTINE MARRIAGE, _Cryptogamia_.

The Orders of the first thirteen Classes are founded on the number
of Females, or Pistils, and distinguished by the names, ONE FEMALE,
_Monogynia_. TWO FEMALES, _Digynia_. THREE FEMALES, _Trigynia_, &c. as is
seen in No. i. which represents a plant of one male, one female; and in
the first Figure of No. xi. which represents a flower with twelve males,
and three females; (for, where the pistils have no apparent styles, the
summits, or stigmas, are to be numbered) and in the first Figure of No.
xii. which represents a flower with twenty males and many females; and in
the last Figure of the same No. which has twenty males and one female;
and in No. xiii. which represents a flower with many males and many
females.

The Class of TWO POWERS, is divided into two natural Orders; into such
as have their seeds naked at the bottom of the calyx, or flower cup; and
such as have their seeds covered; as is seen in No. xiv. Fig. 3. and 5.

The Class of FOUR POWERS, is divided also into two Orders; in one of
these the seeds are inclosed in a silicule, as in _Shepherd's purse_.
No. xiv. Fig. 5. In the other they are inclosed in a silique, as in
_Wall-flower_. Fig. 4.
