Description

Fruit a loculicidalloculicidal:
type of capsular dehiscence, opening longitudinally through the locules (compare septicidal)
capsulecapsule:
a dry, dehiscent fruit derived from a compound ovary
, 90–100 mm long, oblongoblong:
2D shape—much longer than broad with nearly parallel sides, corners are rounded
or ovoidovoid:
3D shape—ovate
, tereteterete:
approximately circular in cross section; width and thickness approximately equal
in transection, beakedbeak:
a usually firm, terminal appendage, sometimes tapered
(persistent stylestyle:
in a flower, the narrow and elongated part of the pistil between the stigma and the ovary; sometimes persisting in fruit
and stigmastigma:
the portion of the pistil receptive to pollen
), with many seeds. Pericarppericarp:
fruit wall or fruit coat
brown or red, dulldull:
reflecting only a low proportion of incident light, with no apparent sheen
, woodywoody:
texture—consisting mainly of indurate lignified tissues, characteristic of or resembling wood
, smooth or ridgedridged:
surface relief—raised, thick ridges, sharp edged or rounded, usually in a series that may cover the entire surface
.

Seeds conicalconical:
3D shape—cone-shaped, with the point of attachment at the broad end
, flattened or triangulartriangular:
2D shape—three relatively straight sides with distinct corners; more angular than teardrop-shaped
in transection, usually with a broad, paperypapery:
texture—papyraceous, chartaceous; very thin, pliable, and readily torn; like paper
, laterallateral:
(of embryo) embryo lies along the side of the seed, generally towards one end; of, at, or from the side; in grasses, can refer to the sides adjacent to the dorsal and ventral sides
wing. Seed coat reddish brown or yellow, dulldull:
reflecting only a low proportion of incident light, with no apparent sheen
, thin, wrinkledwrinkled:
surface relief—shallow, irregular folds and furrows covering the surface; appearing overall though crumpled and then spread out
.

Embryo capitatecapitate:
head-shaped; abruptly enlarged on one end to a relatively short, terminal portion
with obtriangularobtriangular:
2D shape—inversely triangular, with point of attachment at narrow end
cotyledoncotyledon:
a primary leaf of the embryo
, straight, 1/3 to nearly as long as seed, partially filling seed coat.

Endosperm oily.
