प्रश्न
Write down the different positions of floral leaves on the thalamus in detail?
उत्तर
Based on the position of calyx, corolla, and androecium in respect to the ovary on the thalamus, there are three floral whorl conditions. These are
(i) Hypogyny - In this flower, the ovary occupies the highest position on the thalamus, while the petals, sepals, and stamens are separately inserted below the ovary. The ovary in such flowers is said to be superior. E.g., mustard and china rose.
(ii) Perigyny - In this condition, the margin of the thalamus grows upwards to form a cup-shaped structure called calyx tube enclosing the ovary. The ovary here is said to be half inferior. E.g., plum and rose
(iii)Epigyny - In this flower, the margin of thalamus grows upwards enclosing the ovary completely and getting fused with it. The other parts of the flower are above the ovary. Hence, the ovary is said to be inferior. E.g. Sunflower, flowers of cucumber.
