Description

Fruit dehiscentdehiscent:
(v. dehisce) splitting open at maturity to release contents (of a fruit)
, loculicidalloculicidal:
type of capsular dehiscence, opening longitudinally through the locules (compare septicidal)
capsulecapsule:
a dry, dehiscent fruit formed by two or more carpels
, 3–8 mm long, globoseglobose:
3D shape—more or less spherical
, tereteterete:
approximately circular in cross section; width and thickness approximately equal
in transectiontransection:
a cross section; representing a plane made by cutting across an organ at a right angle to its length
, one-seeded, covered by persistent white, wooly perianthperianth:
collective term for calyx and corolla of a flower
. Pericarppericarp:
fruit wall or fruit coat
appears white, pubescentpubescent:
surface relief—bearing hairs
.

Seed globoseglobose:
3D shape—more or less spherical
, 1–2 mm long. Seed coat black, shinyshiny:
uniformly reflecting a high proportion of incident light at all angles
, with phytomelanphytomelan:
carbonaceous, opaque material that usually covers the seed coat to give it a black appearance, common in certain monocot families
crust.

Embryo curvedcurved:
(of embryo) linear embryo is curved into an arch or horseshoe with the ends far apart
, about as long as endospermendosperm:
nutritive starch- and oil-containing tissue present in many seeds
. Endospermendosperm:
nutritive starch- and oil-containing tissue present in many seeds
copious.
