Cannaceae

seed

Fruit a loculicidalloculicidal:
type of capsular dehiscence, opening longitudinally through the locules (compare septicidal)
capsulecapsule:
a dry, dehiscent fruit derived from a compound ovary
, 15–100 mm long, globoseglobose:
3D shape—more or less spherical
to ellipsoidellipsoid:
3D shape—elliptic
, angledangular:
2D shape—having sides that meet at acute or obtuse angles  
in transection, crowned by persistent tepalstepal:
a member of the perianth, when it cannot be differentiated into a calyx and corolla
, with few to many seeds. Pericarppericarp:
fruit wall or fruit coat
brown, green, brown, or white, firm, glabrousglabrous:
without hairs
, with large, soft, conicalconical:
3D shape—cone-shaped, with the point of attachment at the broad end
warts.

Seeds globoseglobose:
3D shape—more or less spherical
, ovoidovoid:
3D shape—ovate
, or ellipsoidellipsoid:
3D shape—elliptic
, tereteterete:
approximately circular in cross section; width and thickness approximately equal
in transection, 3.5–10 mm long. Seeds with a distinct lid for germination on the conspicuous rapheraphe:
a ridge or seam on the seed coat, formed by the portion of the funiculus united to the ovule wall in longitudinally curved ovules
, like an operculumoperculum:
a dehiscent cap (or lid) of a seed or fruit that opens during germination or dehiscence
but unique to the family. Seeds with micropylar collarmicropylar collar:
collar shaped tissue at micropyle
. Seed coat black or brown, shinyshiny:
uniformly reflecting a high proportion of incident light at all angles
, coriaceouscoriaceous:
texture—leathery
or hard, punctatepunctate:
surface relief—dotted with pits or with translucent, sunken glands or with colored dots, similar to pitted
. Seeds are embedded in hairs derived from funiculifuniculus:
(alt. funicle) stalk connecting the ovule (later seed) to the ovary (later fruit) placenta
, sometimes interpreted as arils; hairs remain on the capsulecapsule:
a dry, dehiscent fruit derived from a compound ovary
wall after seeds are shed.

Embryo well developed, linearlinear:
(shape) long, narrow, and uniform in width; (of embryo) embryo is straight and much longer than wide
, extends into depression or cup at one of the seed and surrounded by a thin layer of endosperm and copious, very hard, perispermperisperm:
seed nutritive tissue comparable to the endosperm, but derived from the nucellus (maternal tissue)
.

Nutritive tissue both scanty endosperm and copious, very hard, perispermperisperm:
seed nutritive tissue comparable to the endosperm, but derived from the nucellus (maternal tissue)
.
