notch |
= emargination |
FEATURE |
|
A relatively small, acute sinus at the distal end of a laminar structure. |
|
scar |
|
FEATURE |
|
A discontinuity in surface color and/or relief due to abscission of a structure formerly borne there. |
|
clinandrium pl. clinandria |
|
FEATURE |
|
The cavity in a floral column (gynostemium) within which the anthers are borne. |
|
commissure |
|
FEATURE |
|
Precisely, the joint or common boundary between the facing surfaces of two coherent or mutually appressed structures such as mericarps or stigmas, but traditionally (though imprecisely) applied to such a facing surface itself. |
|
blister |
= bulla, pustule |
FEATURE |
|
A relatively coarse, rounded protrusion or convexity. See also papilla. |
|
axil |
|
FEATURE |
|
The space bounded by and near the vertex of the distal angle between a lateral structure, especially a leaf, and the axis that bears it. |
|
cell 2 (not recommended) |
= chamber (not recommended), locule |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit, sporangium or other organ; not necessarily having any evolutionary integrity. |
|
callus |
|
FEATURE |
|
A small, relatively hard covering, outgrowth, or swelling of tissue; esp. in axes of grass (Poaceae) inflorescences just distal to points of eventual disarticulation. |
|
blotch |
= macula, spot |
FEATURE |
|
An area that differs in color from the rest of a structure's surface. See also eyespot. |
|
enzymatic |
|
exudation |
|
Secreting a digestive exoenzyme; in carnivorous plants. |
|
oil-secreting |
|
exudation |
|
Producing and exuding an oily substance, often aromatic; when oil-secreting glands are indicated in the nominative, often they are called simply oil glands. |
|
glandular 2 |
|
exudation |
|
Anatomically distinct and producing and exuding a particular substance. |
|
laticiferous |
|
exudation |
|
Producing and exuding latex. |
|
salt-excreting |
|
exudation |
|
Accumulating salt and discharging it directly to the exterior in a concentrated aqueous solution, the salt then crystallizing on the exterior following evaporation of the fluid medium; when salt-excreting glands are indicated in the nominative, usually they are called simply salt glands. |
|
nectariferous |
|
exudation |
|
Producing and secreting nectar; when glands are nectariferous, they are usually indicated nominatively as nectaries. |
|
partial |
|
extent |
|
Not reaching fully from the ovary wall or pericarp to the center of the ovary or fruit and/or from the apex to the base of its interior, thus not completely separating adjacent locules, which are recognized and delimited by extrapolating from the incomplete septal boundary(ies), the ovary or fruit nonetheless effectively unilocular. |
|
full |
|
extent |
|
Reaching from the ovary wall or pericarp to the center of the ovary or fruit and from the apex to the base of its interior, thus separating adjacent locules completely. |
