Depending upon the configuration and orientiation of the body of ovule in relation to funiculus three are 6 types of ovules .
A- Orthotropous ovule - It is the straight ovule or erect ovule in which micropyle and funicle remain in straight line .
Example - pollygonum , piper
B - Anatropous ovule - It is invented ovule .In this type of ovule the nucllus is parallel to the funicle and thevmicrophyle and chalaza remain in the stright line . Here the hilum and microphyle lip side by side and are very close to each other .
Example - hibiscus
C - Hemitropous ovule - The body of the ovule is twisted only half way so that it at right angle to the funicle
Example - ranunculus
D - Campylotropous ovule - Here the ovule is horse-shoe shaped and become curved .The funicle is attached .
Example - capparis , brassicaceac
E- Amphitropous ovule - It is a transversely oriented ovule where the embryosac becomes horse-shose shaped . The micropyle is close to funicle .
Example - capsella , papaver , lemma
F- Circinotropous ovule - The ovule is straight with microphyle facing upwards .The funicle is elongated and get coiled around the ovule .
