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. |

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). |

sub-basifixed |
|
fixation |
|
Attached just above its base. |
|
versatile |
|
fixation |
|
Attached in a manner allowing free rotation and declination. |
|
fixed |
|
fixation |
|
Attached to the bearing structure in a manner allowing no significant rotation or declination in relation to it. |
|
basifixed |
|
fixation |
|
Attached at its base. |

coherent |
|
fusion |
equivalent structures |
Joined superficially, with no significant histological continuity. |
|
fasciate(d) |
|
fusion |
equivalent structures |
Abnormally proliferated in size and/or number and more or less connate, the result often monstrous. |
|
discrete |
= distinct |
fusion |
equivalent structures |
