Description

Fruits: Pistil(s) 1; 1-pistillate. Fruit pericarpium; simple; 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.

without central placental mass; without persistent central column; with styles(s); at apexapex:
the point farthest from the point of attachment, or the "tip" of an organ
; not within accessory organ(s); 1-seeded; 1-seeded; with 1-carpellate (assumed); in transection tereteterete:
approximately circular in cross section; width and thickness approximately equal
; apexapex:
the point farthest from the point of attachment, or the "tip" of an organ
not beaked; wall fleshy; indehiscentindehiscent:
not opening on its own, as in a fruit
. Epicarpepicarp:
outer layer of fruit wall or pericarp, if divided into layers; note here used synonymously with exocarp
green, or yellow, or black, or red, or gray; durable; glabrousglabrous:
without hairs
; without armature; smooth; without wing(s); without apicalapical:
at or pertaining to the end of the seed or fruit distal from its point of attachment (i.e., base)
respiratory hole. Mesocarpmesocarp:
the middle layer of the pericarp, if divided into layers
present; fleshy; 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 hookswith hooks:
bristles or spines with curved or backwards pointing tips, or with secondary bristles along their length
(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; not bowl shaped; not nutlike; without winglike beakbeak:
a usually firm, terminal appendage, sometimes tapered
; without caudatecaudate:
tapering to a long, tail-like appendage
appendage(s); at maturity with food reserves, or without food reserves (Lepidoceras); with endosperm; without canavanine. Sarcotestasarcotesta:
pulpy or fleshy outer layer of the seed coat, simulates aril
absent. Testatesta:
seed coat
absent; not differentiated (assumed); without embryo surrounded and capped by viscid tissue. Endosperm smooth; without fatty acid containing cyclopropene; without apicalapical:
at or pertaining to the end of the seed or fruit distal from its point of attachment (i.e., base)
lobes; with chlorophyll and green, or without chlorophyll; without isodiametric faceted surface; without odor. Embryo differentiated from food reserve; well developed; 1 per seed; nearly filling testatesta:
seed coat
(trace or scanty food reserve), or partially filling testatesta:
seed coat
(with food reserve); at one end of seed not extending into a depression or cup; without coleorhiza; without simmondsin; without stomata; not green; with 2 or more cotyledons, or acotyledonous (Lepidoceras peruvianum Kuijt). Cotyledons 2; equal in size; not punctatepunctate:
surface relief—dotted with pits or with translucent, sunken glands or with colored dots, similar to pitted
dotted.

Distribution

General distribution: New World.

Detailed distribution: Middle America and South America.
 

Notes

Endosperm creamy white or in Antidaphne viscoidea light greenish or absent in Lepidoceras. Lepidoceras peruvianum has a globular undifferentiated embryo and acotyledonous. 1-seeded 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.
black, gray, reddish, green. Seed coat has viscin concentrated at its radicular pole. Viscin caps embryo.
