40 THE FLOWER. 
Sometimes these divisions are very evident, being but slightly 
connected, while in other cases, all external marks of them dis- 
appear. When simple, it of course consists of a single carpel. 
(Fig. 10.) 
78. The styLe is that prolonged columnar part of the ovary, 
or rather of each carpel, which bears the stigma at its top. The 
number of the styles, when they are not wanting, always equals 
the number of carpels: but when the carpels are closely united, 
the styles may be united also, into a single compound column, 
or they may even then remain distinct. 
79. The strema is the upper portion, or extremity, of the style, 
extremely various in form, but usually globular. Like the ovary 
and style, it is either simple or compound. When it is com- 
pound it consists of as many united lobes as there are carpels. 
80. The number of distinct styles (or of stigmas, when the 
styles are wanting) constitutes the basis of the artificial orders, 
into whieh the first thirteen classes of Linnzeus are subdivided. 
They are named from the Greek numerals prefixed to the ter- 
mination gynia, (yvv7n, 57, Note,) as follows. 
Order 1. Monogynia, includes all the genera of Yhsche in 
either of the first thirteen classes, with one style 
to the flower. 
Digynia, with two styles to the flower. 
Trigynia, with three styles. 
Tetragynia, with four styles. 
Pentagynia, with five styles. 
Hexagynia, with six styles. 
Heptagynia, with seven styles. 
Octogynia, with eight styles. 
Enneagynia, with nine styles. 
Decagynia, with ten styles. 
. Dodecagynia, with eleven or twelve styles. 
. Polygynia, with more than twelve styles.*

*The orders of the remaining classes are founded upon characters not depend- 
ing upon the pistil, and are as follows: — 
The orders of class 14, Didynamia, are only two; 
1. Gymnospermia, with seeds apparently naked. ; 
2. Angiospermia, with seeds evidently in a seed-vessel, or pericarp.
