Identify the type of flowers based on the position of calyx, corolla and androecium with respect to the ovary from the given figures (a) and (b) [Figure]
- (a) Epigynous; (b) Hypogynous
- (a) Hypogynous; (b) Epigynous
- (a) Perigynous; (b) Epigynous
- (a) Perigynous; (b) Perigynous
Answer
(4) (a) Perigynous; (b) Perigynous
Solution
In both (a) and (b), the thalamus grows up around the ovary as a cup, but it is not fused with the ovary; the ovary sits free in the centre.
Calyx, corolla and androecium arise from the rim of the cup, at about the same level as the ovary, so the ovary is half inferior.
Such flowers are perigynous (e.g. plum, rose, peach). So both (a) and (b) are perigynous.
Answer: (4)
