FLOWER:GYNOECIUM or PISTIL: It is innermost and fourth whorl of the flower. It is the central part of the flower and female reproductive organ. It is made up of one or more carpels. Carpels are also called MEGASPOROPHYLLS. A typical carpel consists of three parts such as ovary, style and stigma. NUMBER OF CARPELS:Based on the number of carpels, the gynoecium in angiosperms is of the following types.MONOCARPELLARY GYNOECIUM: One carpel is present. Example: Dolichos.BICARPELLARY GYNOECIUM: Two carpels are present. Example: Solanum,TRICARPELLARY GYNOECIUM: Three carpels are present. Example: Allium.TETRACARPELLARY GYNOECIUM: Four carpels are presnt. Example: Oenothera.PENTACARPELLARY GYNOECIUM: Five carpels are present. Example: Hibiscus.MULTICARPELLARY GYNOECIUM: Many carpels or more than five carpels are present. Example: Abutilon.FUSION OF CARPELS: In the gynoecium, carpels are present either in free or fused state. Based on this, two types of gynoecium are classified as follows:APOCARPOUS GYNOECIUM: Carpels are free in the gynoecium. Example: Nelumbo, Michelia.SYNCARPOUS GYNOCEIUM: Carpels are fused in the gynoecium. Example: Datura. In Hibiscus, carpels are fused partly.OVARY:The basal swollen part of the gynoecium is called OVARY.It encloses the ovules. It is shows one to many chambers or compartments, due to the presence of septa, formed by the fusion of margins of adjacent of carpels. Each chamber in the ovary is called LOCULE.Based on the number of locules in the ovary, ovary is of different types. as follows:UNILOCULAR OVARY: One locule is present. Example: Dolichos.BILOCULAR OVARY: Two locules are present. Example: Solanum.TRILOCULAR OVARY: Three locules are present. Example: Allium TETRALOCULAR OVARY: Four locules are present. Example: Ipomea PENTALOCULAR OVARY: Five locules are present. Example: Hibiscus MULTILOCULAR OVARY: many locules are present . Example: Abutilon Generally in every ovary number of locules are equal to the number of carpels. But in some plants number of locules may be less or more than that of number of carpels.Examples: Datura -- the ovary contains two carpels and four locules due to the formation of false septa. Tridax -- the ovary contain two carpels and one locule.
