Description

Fruits: Pistil(s) compound; 1; 1-pistillate; with carpels united. Fruit pericarpium; multiplemultiple:
fruit formed from several flowers clustered in one mass
, or simplesimple:
fruit formed from a single flower with one pistil, solitary carpel or several fused carpels
; 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.
(not Spjut); baccetum (Spjut 6 families: Annonaceae, Austrobaileyaceae, Lardizabalaceae, Ranunculaceae, Schisandraceae, Winteraceae); without persistent central column; not within accessory organ(s); many-seeded; many; with 12–300-carpellate (20–30); with carpels separate; without sterilesterile:

carpels; not sulcatesulcate:
surface relief—having one or more elongate, relatively narrow and shallow depressions or grooves
; in transectiontransection:

texture—fairly firm and dense, juicy or at least moist, and easily cut
; indehiscentindehiscent:

. Epicarpepicarp:

; without armature; smooth; without wing(s); without apicalapical:

respiratory hole. Mesocarpmesocarp:
the middle layer of the pericarp, if divided into layers
present; fleshyfleshy:
texture—fairly firm and dense, juicy or at least moist, and easily cut
; composed of 1 unified layer; without lactiform cavity system. Endocarpendocarp:
the inner layer of the pericarp, if divided into layers
absent. Funiculusfuniculus:
(alt. funicle) stalk connecting the ovule (later seed) to the ovary (later fruit) placenta
short; short without seed bearing hooks (retinacula); not persisting in fruit after seed shed.

Seeds: Arilaril:
(broad sense) appendicular structure that wholly or partly envelops a seed and is produced from or a modification of the funicle, raphe, or outer integument; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored
absent. Seed larger than minute; 10 to less than 25 mm long; 15 mm long, or 19 mm long; D-shapedD-shaped:
2D shape—has one straight margin and one curved margin, resembling the shape of the letter D
, or reniformreniform:

; in transectiontransection:
a cross section; representing a plane made by cutting across an organ at a right angle to its length

a usually firm, terminal appendage, sometimes tapered
; without caudatecaudate:
tapering to a long, tail-like appendage
appendage(s); at maturity with food reserves; with endospermendosperm:

; without canavanine. Sarcotestasarcotesta:
pulpy or fleshy outer layer of the seed coat, simulates aril

at, on, or close to the margin or border
tissue; without fleshyfleshy:
texture—fairly firm and dense, juicy or at least moist, and easily cut
or leatheryleathery:
texture—moderately thick, tough, and very pliable
layer over hard layer; tight; surface smooth, or unsmooth; with crease or line separating cotyledons from hypocotyl-radicle, or without crease or line separating cotyledons from hypocotyl-radicle; with notch along margin where cotyledons from hypocotyl-radicle tip approaching each other; without glands; without bristles; glabrousglabrous:
without hairs
; without wings; without collar; without operculumoperculum:
a dehiscent cap (or lid) of a seed or fruit that opens during germination or dehiscence
; colored; monochrome; yellow, or brown (all shades) (including gray-); not becoming mucilaginousmucilaginous:
resembling mucilage; moist and sticky
when wetted; surrounding food reserve. Hilumhilum:
on seeds, the scar indicating where the funiculus was attached; on grass caryopses, the scar visible on the outer fruit surface revealing where the seed is attached on the inner fruit wall surface; or in Asteraceae cypselae, the scar visible on the outer fruit wall revealing where the fruit was attached to the receptacle
larger than punctatepunctate:
surface relief—dotted with pits or with translucent, sunken glands or with colored dots, similar to pitted

Distribution

General distribution: New World and Old World.

Notes

Spjut: Kadsura carpels aggregated into a head but apparently not concrescent. Cronquist: Fruit berrylike carpels, these on somewhat elongated axisaxis:
a straight line through the center of a structure around which the parts are usually symmetrically arranged, as in the stem or rachis of an inflorescence
(Schisandra) or in a dense head (Kadsura).
