Funiculus short; short without seed bearing hooks (retinacula); not persisting in fruit after seed shed.
Seeds
Aril Corner quoted Svedelius (1911): Actinidia chinensis seeds have "jacket around seed appears to be the aril", a funicular aril, he also included Saurauia present, or absent (Corner: Actinidia polygama "exarillate". Most authors do not mention an aril.); a true aril; white; well developed; fleshy; encompassing; fleshy. Seed larger than minute; less than 1 mm long, or 1 to less than 5 mm long; 0.7–2.5 mm long; not bowl shaped; not nutlike; without winglike beak; without caudate appendage(s); at maturity with food reserves; with endosperm; without canavanine. Sarcotesta present; fleshy. Testa present; with fleshy or leathery layer over hard layer; surface unsmooth; surface with merged raised features; surface reticulate; without crease or line separating cotyledons from hypocotyl-radicle; without notch along margin where cotyledons from hypocotyl-radicle tip approach each other; without glands; without bristles; without wings; without collar; without operculum; colored; monochrome; brown (all shades); crustaceous; not becoming mucilaginous when wetted. Endosperm development cellular; copious; fleshy-firm (Actinidia and Clematoclethra), or mealy (Saurauia); smooth; without starch; with oils and proteins; without fatty acid containing cyclopropene; without apical lobes; without chlorophyll; without isodiametric faceted surface; without odor.
Embryo differentiated from food reserve; well developed; 1 per seed; partially filling testa (with food reserve); 0.75–0.8 times the length of food reserve; at one end of seed not extending into a depression or cup; axile and centric; linear; straight, or C-shaped (slightly); without coleorhiza; without simmondsin; without stomata; not green; with 2 or more cotyledons. Cotyledons 2; well developed; 0.25–0.5 times length of embryo; as wide as hypocotyl-radicle (or just a little larger); massive; flat; smooth; equal in size; not punctate dotted. Hypocotyl-radicle well developed; straight; not thickened.

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
