|
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. |
|
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. |
|
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. |
|
stipule scar |
|
FEATURE |
|
A scar on a stem or petiole due to abscission of a stipule; having an outline like that of a transverse section through the base of the stipule inserted there; variously disposed, usually in pairs, adjacent to a point of leaf insertion, sometimes confluent with the leaf scar, sometimes confluent with stipule scars associated with an opposite leaf, the two sets of scars then more or less encircling the axis. |
|
papilla pl. papillae |
|
FEATURE |
|
A small, conoidal protrusion resembling a pimple. See also pustule (blister, bulla). |
|
ridge |
|
FEATURE |
|
A very narrow, elongate, relatively low protrusion; esp. on fruits in Apiaceae (Umbelliferae). |
|
spot |
= blotch, macula |
FEATURE |
|
An area that differs in color from the rest of a structure's surface, usually due to differing coloration. See also eyespot. |
|
clinandrium pl. clinandria |
|
FEATURE |
|
The cavity in a floral column (gynostemium) within which the anthers are borne. |
|
blister |
= bulla, pustule |
FEATURE |
|
A relatively coarse, rounded protrusion or convexity. See also papilla. |
|
suture |
|
FEATURE |
|
An evident line of ontogenetic union. |
|
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. |
|
pustule |
= blister, bulla |
FEATURE |
|
A relatively coarse, rounded protrusion or convexity. See also papilla. |
|
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. |
|
lumen pl. lumina |
|
FEATURE |
|
A space enclosed by the wall(s) or membrane(s) of a structure. |
|
stoma 2 (strict sense) pl. stomata |
= stomatal pore |
FEATURE |
|
The aperture between and regulated by the two guard cells of a stomate (stomatal apparatus). |
