Fruit dehiscentdehiscent:

, septicidalsepticidal:
type of capsular dehiscence, opening longitudinally by separating between the septa of adjacent carpels
or loculicidalloculicidal:
type of capsular dehiscence, opening longitudinally through the locules (compare septicidal)
capsulecapsule:
a dry, dehiscent fruit formed by two or more carpels
or indehiscentindehiscent:
not opening on its own, as in a fruit
, berryberry:
an indehiscent, fleshy fruit with one or a few to many seeds. The flesh may be homogenous throughout. Or, if the outer part is hard, firm, or leathery, referred to as an hesperidium. Septa are present in some, and the seeds may be arillate or with a fleshy testa.
(Clintonia, Medeola, Prosartes, Streptopus), 4-90 mm long, globoseglobose:

to angularangular:
2D shape—having sides that meet at acute or obtuse angles  
, tereteterete:

in transectiontransection:

in a flower, the narrow and elongated part of the pistil between the stigma and the ovary; sometimes persisting in fruit
(Prosartes), winged in some species of Calochortus and Lilium, rarely beakedbeaked:
a usually firm, terminal appendage, sometimes tapered
, few to many seeded. Berryberry:
