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
, 2–15 mm long, globoseglobose:
3D shape—more or less spherical
to conicalconical:
3D shape—cone-shaped, with the point of attachment at the broad end
, tereteterete:
approximately circular in cross section; width and thickness approximately equal
or angledangular:
2D shape—having sides that meet at acute or obtuse angles  
in transection, beakedbeak:
a usually firm, terminal appendage, sometimes tapered
, perianthperianth:
collective term for calyx and corolla of a flower
persistent, stylesstyle:
in a flower, the narrow and elongated part of the pistil between the stigma and the ovary; sometimes persisting in fruit
persistent or not, with many seeds. Pericarppericarp:
fruit wall or fruit coat
green, orange, or reddish brown, chartaceouschartaceous:
papery, papyraceous
, ribbedribbed:
surface relief—wide, prominent, linear ridges that are generally rounded and longitudinally situated on the surface
, sometimes pubescentpubescent:
surface relief—bearing hairs
.

Seeds oblongoblong:
2D shape—much longer than broad with nearly parallel sides, corners are rounded
to linearlinear:
(shape) long, narrow, and uniform in width; (of embryo) embryo is straight and much longer than wide
, tereteterete:
approximately circular in cross section; width and thickness approximately equal
in transection, 0.4–11 mm long, often appearing bristle-tailed. Seed coat white or yellow, shinyshiny:
uniformly reflecting a high proportion of incident light at all angles
, deeply sulcatesulcate:
surface relief—having one or more elongate, relatively narrow and shallow depressions or grooves
, reticulatereticulate:
surface relief—netted, raised walls or concave grooves forming a net-like surface pattern with flat, concave, or convex interspaces
or striatestriate:
surface relief—having fine, parallel lines, grooves or ridges
.

Embryo small, globoseglobose:
3D shape—more or less spherical
to ovoidovoid:
