Unformatted text preview: Arrangement of the ovules (seeds) in the ovary (fruit). Ovary Ovules Marginal:
1 double-row of
ovules. 1 carpel. Parietal: Inner
Syncarpous. Free central:
Axile: Ovules in
center of partitioned Column in center
of open ovary
ovary. Syncarpous. Fruits that are Fleshy at Maturity
Drupe: Derived from 1 carpel. 1 seed. Outer fruit wall fleshy,
inner wall a boney ( “pit”) enclosing seed.
Berry: Fruit wall soft with 2 or more seeds (many variants). Common Berry Variations.
Hesperidium: Leathery rind with aromatic oils. Internal
sections (=carpels) very evident. Citrus (Rutaceae).
Pepo: Leathery rind. Melons, pumpkins, squash, etc.
(Cucurbitaceae). Dry, Indehiscent Fruits
(seeds not released at maturity)
Achene: Small,1 seed, free from ovary wall. Many plant groups.
Cypsela : Achene-like fruit with plume derived from calyx.
Typical of sunflower family (Asteraceae).
Samara: Winged achenes. Samaras Cypsela Dry, Indehiscent Fruits
Caryopsis (grain): 1 seed, fused to ovary wall. Grasses
(Poaceae). Includes corn wheat rice, etc!
Nut: Hard, boney fruit wall encloses 1 seed (other ovules
aborted). Similar to achene but larger.
Nut Dry, Dehiscent Fruits (Open to release seeds at maturity)
Capsule: Split or open in several places & release seeds.
Derived from >1 carpel.
Many types based on how they open.
Numerous botanical groups. Dry, Dehiscent Fruits (Open to release seeds at maturity)
Folicle: Splits along 1 line of weakness. From 1 carpel.
Trumpet creeper, milkweed.
Legume: Splits along 2 lines of weakness. From 1 carpel.
Legume family (Fabaceae). “Fleshy” legumes (green
beans, etc.) are harvested immature before they dry.
beans, Folicle Separating Fruits
Schizocarp: Fruit separates into 1or ½ -carpel sections,
each section containing seeds.
Carrot/ parsley family (Apiaceae) -spilts into 2 achenes.
Maple (Acer) splits into 2 winged-achenes. “Double fruit” of maple Fruits From Both Ovary & Non-ovary
Accessory Strawberry type: Receptacle enlarges & engulfs multiple
carpels (apocarpous flower).
Pome: Receptacle enlarges, engulfs a syncarpous ovary.
(apple pear). Most of fruit = receptacle; ovary = “core”.
(apple Fruits From More than 1 Pistil
Aggregate fruit: Combined ovaries of an apocarpous flower:
Raspberry, Magnolia. Fruits Derived from More than 1 Flower
Multiple fruit: Combined ovaries of several flowers (an
Pineapple, fig, mulberry, etc. Supplement:
