Fig. 92 shows an apocarpoiis gynse- cium composed of three carpels. SYNCARPOUS GYN^CIUM. When a flower possesses more than one carpel, and its carpels cohere together to form a single body, the gynsecium is said to be syncarpous. In such a gynsecium the ovule- containing parts (ovaries) of the carpels are joined together to form a single ovary, which is also described as being syncarpous (figs- 93. 94, 95)- But the styles may remain separate along their whole

In such a gynsecium the ovule- containing parts (ovaries) of the carpels are joined together to form a single ovary, which is also described as being syncarpous (figs- 93. 94, 95)- But the styles may remain separate along their whole lengths (fig. 9S); or along part of their lengths (fig. 95). Again, not only may the ovaries be com- pletely fused, but also the styles, so that only Figs. 92-95.âA gynaecium composed of three carpels. ,i ,â .

The syncarpous ovary, representing as it does parts of several carpels, may have several chambers, each corresponding to one carpel.* Thus the Hyacinth has three carpels joined to form a single ovary, which is three- chambered; or the syncarpous ovary may have one general chamber, the wall of which is formed by several carpels, joined together ( Violet). PLACENTATION. The mode of arrangement of the ovule-bearing portionsâ the placentaeâof the ovary is referred to under the head of * Rarely these chambers of the ovary are further sub-divided by additional partitions, so that the chambers of the ovary are more numerous than the carpels composing itâ Labiatse, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the origina
