The 4-winged indehiscent fruit forms from a 4-carpellate ovary and typicaly has three single-seeded locules in which most of the seeds are aborted (Pirani, 1998).

We use the term "samaroid" in application to fruits that are similar to samaras in being indehiscent and having the wing developed from ovary (rather than perianth or bracts), but which may possess more than one seed.

Indehiscent fruits, in which the entire fruit comprises the dispersal unit, characterize many orders and families, e.

The indehiscent fruit is formed from a superior ovary of multiple carpels, apparently with each carpel developing a marginal wing, such that a single fruit may have 6-20 wings.

The fruit of Strasburgeria is large, indehiscent, and fibrous, with persistent sepals and style and a distinctive odor of ripe apples.

1), yet Ixerba has a coriaceous, dehiscent fruit, whereas that of Strasburgeria is fibrous and indehiscent.

Fruit a septicidal to loculicidal capsule, indehiscent pod, or drupe; seeds with variable testa cells; embryo with 2 cotyledons.

Fruit a loculicidal capsule, indehiscent pod, or drupe; seeds with variable testa cells; embryo with 2 cotyledons.

Phylogenetic classification of Ericaceae: molecular and morphological evidence

The first group contained the "Carisseae," "Ambelanieae" and "Macoubeeae" (fruit a fleshy, indehiscent berry) and the "Chilocarpeae" and "Tabernaemontaneae" (fruit consisting of dehiscent follicles with arillate seeds).

The other two tribes with indehiscent fruits and a fleshy inner pericarp recognized by Pichon (1948a) and Leeuwenberg (1994), the "Ambelanieae" and the "Macoubeeae," differ from the "Carisseae" in having specialized anthers with winglike margins formed into hard, lignified guide rails, such as are found in the Tabernaemontaneae as traditionally defined.

Anthers free from style head; corolla-lobe aestivation in bud typically sinistrorse (overlapping to the left), rarely dextrorse; fruit dehiscent or indehiscent, syncarpous or apocarpous, a berry, drupe, follicle, or capsule; seeds naked, with wings, or arils, but almost never with coma Rauvolfioideae at one end 2.
