Fruit (intact or entire).

Description

Fruits: Pistil(s) 1; 1-pistillate. Fruit without persistent central column; within accessory organ(s); within calyxcalyx:
the outer whorl of the perianth; all the sepals of a flower
(subtending); soft calyxcalyx:
the outer whorl of the perianth; all the sepals of a flower
(soft); without sterilesterile:
lacking male and/or female reproductive parts; also, not producing fruit or seed
carpels; apexapex:
the point farthest from the point of attachment, or the "tip" of an organ
not beaked; wall chartaceouschartaceous:
papery, papyraceous
, or leatheryleathery:
texture—moderately thick, tough, and very pliable
(probably one of these answers); indehiscentindehiscent:
not opening on its own, as in a fruit
(according to literature). Epicarpepicarp:
outer layer of fruit wall or pericarp, if divided into layers; note here used synonymously with exocarp
durable; not glabrousglabrous:
without hairs
(with hairs); hairs not glandularglandular:
surface relief—covered with small, raised secretory glands, regular or irregularly shaped, translucent or opaque, and maybe distinctly colored
; without armature; with 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. Endocarpendocarp:
the inner layer of the pericarp, if divided into layers
present; not separating from exocarpexocarp:
outer layer of fruit wall or pericarp, if divided into layers; note here used synonymously with epicarp
; thin; not splitting into 1-seeded pyrenes; smooth; without wing; without operculumoperculum:
a dehiscent cap (or lid) of a seed or fruit that opens during germination or dehiscence
; without secretory cavities; without mechanism for seedling escape; without grooves; without longitudinallongitudinal:
of or relating to length or the lengthwise dimension
ridges. 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); 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
present (Mueller, 1861, for arillate seed illustration); a true 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
; fleshy; of funicularfuniculus:
(alt. funicle) stalk connecting the ovule (later seed) to the ovary (later fruit) placenta
origin; marginalmarginal:
at, on, or close to the margin or border
; fimbriate-laciniate (fingerlike projections). Seed circularcircular:
(of embryo) linear embryo is curved into an "O" shape
(more or less); in transection compressedcompressed:
flattened; in grasses, used to denote compression (not necessarily flattened) either laterally or dorsiventrally
; 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; with endosperm; without canavanine. Sarcotestasarcotesta:
pulpy or fleshy outer layer of the seed coat, simulates aril
absent. Testatesta:
seed coat
absent; adhering to epicarpepicarp:
outer layer of fruit wall or pericarp, if divided into layers; note here used synonymously with exocarp
; without embryo surrounded and capped by viscid tissue. Endosperm scant; 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; 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); 3 times the length of food reserve (estimated); at one end of seed not extending into a depression or cup; axileaxile:
on or of the axis
and centric; linearlinear:
(shape) long, narrow, and uniform in width; (of embryo) embryo is straight and much longer than wide
; flatly coiledcoiled:
(of embryo) linear embryo is very long and bent to form a coil whereby one end of the embryo is on the outside and the other end near the middle of the seed
(circinatecircinate:
3D shape—terete and rolled downward from the apex in a tight coil
); without coleorhiza; without simmondsin; without stomata; not green; with 2 or more cotyledons. Cotyledons 2; moderately developed; 0.8 times length of embryo; as wide as hypocotyl-radicle; not concealing hypocotyl-radicle; not foliaceous; controtiplicate; smooth; with apicesapex:
the point farthest from the point of attachment, or the "tip" of an organ
entire; with margins separate; basally entire; equal in size; not punctatepunctate:
surface relief—dotted with pits or with translucent, sunken glands or with colored dots, similar to pitted
dotted. Hypocotyl-radicle moderately developed; curvedcurved:
(of embryo) linear embryo is curved into an arch or horseshoe with the ends far apart
; not thickened.

, pendulous within the calyxcalyx:
