I believe all the three flowers shared here are same. Need to do some research for the id. Wwhen ovary is at the highest position (petals and sepals arising from position below the ovary. Ovary is placed on thalamus) then it is called Superior Ovary. But there are times when ovary is placed inside a cup shaped thalamus with petals and sepals at the margins of the thalamus, then the ovary is called Semi inferior. In inferior ovary, thalamus surrounds the ovary completely and petals and sepals are placed on the top.
