Reproductive Morphology — BIO BOTANY STD 11 — Question

This fruit type of intermediate between dehiscent and indehiscent fruit. The fruit instead of dehiscing rather splits into number of segments, each containing one or more seeds. They are of following types:

1. Cremocarp: Fruit develops from bicarpellary, syncarpous, inferior ovary and splitting into two one seeded segments known as mericarps. e.g., Coriander and Carrot.
2. Carcerulus: Fruit develops from bicarpellary, syncarpous, superior ovary and splitting into four one seeded segments known as nutlets, e.g., Leucas, Ocimum and Abutilon.
3. Lomentum: The fruit is derived from monocarpellary, unilocular ovary. A leguminous fruit, constricted between the seeds to form a number of one seeded compartments that separate at maturity, e.g., Desmodium, Arachis and Mimosa.
4. Regma: They develop from tricarpellary, syncarpous, superior, trilocular ovary and splits into one – seeded cocci which remain attached to carpophore, e.g., Ricinus and Geranium.
