Heliconiaceae

Fruit a schizocarpschizocarp:
usually dry fruit splitting between two or more locules to form distinct, indehiscent, usually one seeded segments; fruit derived from a single, superior or inferior, compound ovary; compare to mericarp
, splits into three fleshy mericarpsmericarp:
a one-seeded section (carpel) of a schizocarp, as in Apiaceae fruits (compare schizocarp)
(often interpreted as drupesdrupe:
(indehiscent drupe) a fleshy, indehiscent fruit with one more hard pits enclosing seeds, derived from single, superior, simple or compound ovary; (dehiscent drupe) a fruit with a dry or fibrous to fleshy or leathery outer husk that early to tardily breaks apart (or opens), exposing one or more nutlike pits enclosing the seeds
), 7–21 mm long, squaresquare:
2D shape—geometric figure bounded by 4 straight sides of equal length and 4 90º-angles
to trigonoustrigonous:
3D shape—having three faces that meet at distinct angles; triangular in outline
, angledangular:
2D shape—having sides that meet at acute or obtuse angles  
in transection, each mericarpmericarp:
a one-seeded section (carpel) of a schizocarp, as in Apiaceae fruits (compare schizocarp)
with operculateoperculum:
a dehiscent cap (or lid) of a seed or fruit that opens during germination or dehiscence
single-seeded thick-walled stone. Pericarppericarp:
fruit wall or fruit coat
usually blue, sometimes red, orange or yellow, thin, smooth, sometimes pubescentpubescent:
surface relief—bearing hairs
.

Seeds triangulartriangular:
2D shape—three relatively straight sides with distinct corners; more angular than teardrop-shaped
, each with an operculumoperculum:
a dehiscent cap (or lid) of a seed or fruit that opens during germination or dehiscence
but no micropylar collarmicropylar collar:
collar shaped tissue at micropyle
, 10–17 mm long. Seed coat hard, ridgedridged:
surface relief—raised, thick ridges, sharp edged or rounded, usually in a series that may cover the entire surface
, pittedpitted:
surface relief—surface with small depressions in which the areas between the hollows do not take on the appearance of a true reticular net
, or wartywarty:
surface relief—distinct, rounded projections that are large relative to the fruit size; tuberculate, verrucose
, with a larger than punctatepunctate:
surface relief—dotted with pits or with translucent, sunken glands or with colored dots, similar to pitted
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
.

Embryo well developed, foliatefoliate:
appearing leaf-like
or linearlinear:
(shape) long, narrow, and uniform in width; (of embryo) embryo is straight and much longer than wide
, straight, basalbasal:
at or pertaining to the point of attachment; (of embryo) embryo occupies one end of the seed
, embedded in nutritive tissue, sometimes acotyledonous.

Endosperm copious; thin perispermperisperm:
seed nutritive tissue comparable to the endosperm, but derived from the nucellus (maternal tissue)
also present.
