|
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. |
|
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. |
|
blotch |
= macula, spot |
FEATURE |
|
An area that differs in color from the rest of a structure's surface. See also eyespot. |
|
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. |
|
locule |
= cell (not recommended), chamber (not recommended) |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit, sporangium or other organ; not necessarily having any evolutionary integrity. |
|
pore |
|
FEATURE |
|
A small aperture or opening in a wall or covering that allows transport between interior and exterior. |
|
sinus pl. sinus, sinuses |
|
FEATURE |
|
The space, indentation, or invagination (or, for some descriptive purposes, the outline thereof) between and delimiting any two consecutive or adjacent lobes or teeth of a structure. |
|
scrobis pl. scrobes |
= fovea, pit |
FEATURE |
|
A small, rounded depression. |
|
tetrad scar |
|
FEATURE |
|
A surficial ridge or angle resulting from coherence with other spores produced from the same mother cell. |
|
equatorial ridge |
|
FEATURE |
|
A circumferential ring about a megaspore in the plane of its equator, raised above the remainder of the wall surface; in some heterosporous taxa of Polypodiophyta. |
|
centralium pl. centralia |
|
FEATURE |
|
A central longitudinal cavity within the seed; esp. in Arecaceae (Palmae). |
|
face |
|
FEATURE |
|
A relatively large, flat or shallowly curved portion of the external surface of a three-dimensional structure, bounded by more or less distinct topological discontinuities. |
|
micropyle |
|
FEATURE |
|
The small pore in the integuments of an ovule at its apex, through which the pollen tube grows; or the corresponding aperture or scar in the coat of the seed that develops subsequently. |
|
bud-scale scar |
|
FEATURE |
|
A scar on a stem due to abscission of a bud scale. The scar(s) encircle(s) the axis to which the bud was terminal, each single scar having an outline like that of a transverse section through the base of the bud scale that was inserted there. Sets of bud scale scars (one set per bud) usually delimit seasonal stem growth increments in temperate zone taxa. |
|
groove |
= colpus, fossula, furrow, sulcus, vallecula |
FEATURE |
|
A longitudinal depression that is relatively shallow and narrow. |
|
punctum pl. puncta |
= dot |
FEATURE |
|
A small, generally round sector of distinct coloration or relief. |
|
surface |
|
FEATURE |
|
The exterior or bounding area or layer of any structure, regarded as being infinitely thin; usually described as to relief, reflectance, and/or vesture. |
|
papilla pl. papillae |
|
FEATURE |
|
A small, conoidal protrusion resembling a pimple. See also pustule (blister, bulla). |
