Description

Fruit dehiscent, septicidalsepticidal:
type of capsular dehiscence, opening longitudinally by separating between the septa of adjacent carpels
winged capsulecapsule:
a dry, dehiscent fruit formed by two or more carpels
, 55–90 mm long, fusiformfusiform:
spindle-shaped; broadest at the middle and tapering at both ends
to trigonoustrigonous:
3D shape—having three faces that meet at distinct angles; triangular in outline
, tereteterete:
approximately circular in cross section; width and thickness approximately equal
to triangulartriangular:
2D shape—three relatively straight sides with distinct corners; more angular than teardrop-shaped
in transectiontransection:
a cross section; representing a plane made by cutting across an organ at a right angle to its length
, stylestyle:
in a flower, the narrow and elongated part of the pistil between the stigma and the ovary; sometimes persisting in fruit
persistent, many seeded. Pericarppericarp:
fruit wall or fruit coat
brown, chartaceouschartaceous:
=papery, papyraceous
.

Seed linear linear:
(shape) long, narrow, and uniform in width; (of embryo) embryo is straight and much longer than wide
to oblongoblong:
2D shape—much longer than broad with nearly parallel sides, corners are rounded
, polygonalpolygonal:
=angular
or falcatefalcate:
shaped like a scythe or sickle
, 5–6 mm long. Seed coat brown, papillatepapillate:
surface relief—bearing minute, distinct, broad-based projections, tapering to a rounded apex
, and densely covered with colorless hairs (appearing felted).

Embryo linear, curvedcurved:
(of embryo) linear embryo is curved into an arch or horseshoe with the ends far apart
or straight, about 1/2 the length of the seed. Endospermendosperm:
nutritive starch- and oil-containing tissue present in many seeds
copious, starchless.
