Xvi INTRODUCTION TO BOTANY. 
A compound ovary is, 
bi-, tri-, quadri-, etc., or multilocular, according to the number of the 
cells, or loculi, 2, 3, 4, or many. 
110. In general the number of cells or dissepiments, complete or partial, 
or of rows of ovules, corresponds with that of the carpels, of which the 
ovary is composed. But sometimes each carpel is divided completely or 
partially into two cells, or has two rows of ovules, so that the number of 
carpels appears double what it really is. Sometimes, again, the carpels 
are so completely combined as to form a single cell, with a single ovule, 
although it really consists of several carpels; but in these cases the ovary 
is generally described as it appears, as well as such as it is theoretically 
supposed to be. 
111. In apocarpous ovaries the styles are usually free, each bearing its 
own stigma; very rarely (as in Asclepiadee) the larger portion of the 
styles or the stigmas alone are united, while the carpels remain separate. 
112. Syncarpous flowers are said to have, 
several styles, when the styles are free from the base. 
one style with several branches, when the styles are connected at the 
base, but separate below the point where the stigmas or 
stigmatic surfaces commence. 
one simple style with several stigmas, when united up to the point 
where the stigmas or stigmatic surfaces commence, and then 
separating. 
one simple style, with branched, lobed, toothed, notched, or entire stigma 
(as the case may be) when the stigmas also are more or less 
united or subdivided. 
113. In general the number of styles, or of branches of the style or 
stigmas, is the same as that of the carpels, but sometimes that number is 
doubled, especially in the stigmas, and sometimes the stigmas are much 
subdivided or penicillate, that is, divided into a tuft of hair-like branches, 
as in some species of Drosera. 
114. An entire stigma is said to be punctiform when it appears like 
the mere point of the style; capitate, when globular, like the head of a pin. 
115. The placenta is the part of the inside of the ovary to which ovules 
are attached, sometimes a mere point or ine on the inner surface, often 
more or less thickened or raised. Placentation therefore is the indication 
of the part of the ovary to which ovules are attached. 
116. The placentas are, 
axile, when the ovules are attached to the axis or centre, that is, in 
plurilocular ovaries, when they are attached to the inner angle 
of the cell; in unilocular simple ovaries (which have almost 
always an excentrical style or stigma) when the ovules are 
attached to that side of the ovary nearest to the style ; in uni- 
locular compound ovaries, when the ovules are attached to a 
central axis, cushion, or column, rising up from the base of the 
cavity, and either free at the top (free central placenta), or 
attached also to the summit of the cavity. 
parietal, when the ovules are attached to the inner surface or walls 
of the cavity of a one-celled compound ovary. Parietal pla- 
centze are usually slightly thickened or raised lines; some- 
times broad surfaces nearly covering the inner surface of the 
cavity ; sometimes projecting far into the cavity and constitu- 
ting partial dissepiments, and even meeting in the centre, but 
without cohering there. In the latter case the distinction 
between the one-celled and several-celled ovary sometimes 
almost disappears.
