Will not spontaneously burst open to release it's contents, usually spores or seeds.

Indehiscent fruit do not split open and release their seed when they mature. INDEX FOSSILS Index fossils are commonly found fossils that are limited in time span. They help in dating other fossils. For example: trilobites were common during the Paleozoic, but not found before the Cambrian period. Ammonites were common during the Mesozoic Era, but not found after the Cretaceous period. Another example: the oldest-known ostracods are from the Cambrian period; they became widespread during the Ordovician and remain so.

Not opening to release it's contents.

Not opening by definite lines or pores. Compare "dehiscent".

seed-bearing plant part (fruit) that does not open by valves or along regular lines upon maturity.

not opening to release seeds.

Fruit that remains closed upon reaching maturity.

Not opening at maturity.
