apex pl. apices |
|
CHARACTER |
|
Configuration of the uppermost, distal, or terminal portion of a structure, its extent determined somewhat subjectively in relation to the shape of the structure as a whole. The concept of apex varies from one descriptive context to another, since the apex is not a clearly delimited, morphologically distinct entity. The terms for describing apical condition are not strictly coordinate logically — some are more inclusive than others, some describe conditions involving what can be regarded as appendages, and some refer to the apex in a developmental as well as a strictly topological sense — and precise characterization may require using more than one descriptor. The semantic antecedent of some descriptors is "apex," whereas the antecedent of others is the structure as a whole (e.g., leaf ). |

palea 1 pl. paleae, paleas |

A small papery (chartaceous) to membranous bract borne on the compound receptacle (torus) of a capitulum (head) in Asteraceae (Compositae). |

|
elliptic(al) 2 |
= oval |
plane shape |
|
Elongate, widest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
|
fine-pitted |
= foveolate, scrobiculate |
relief |
|
Finely pitted (foveate). |
|
sigmoid 1 |
= S-shaped |
course |
|
Curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |
|
glochidium pl. glochidia |
= glochid; < bristle, capillus, hair, seta, trichome |
STRUCTURE |
|
A capillus (hair) or bristle (seta) that bears one or more barbs; esp. in Cactaceae. |
|
stellate 3 |
= star-shaped |
solid shape |
|
Having a distal aspect like the stylized shape of a star; stipitate or sessile with elongate branches or appendages radiating widely in three dimensions from a common point at the apex of the proximal axis or, when sessile, upon the bearing surface. |
|
hyaline |
= pellucid; > translucent, transparent |
coloration |
|
Transmitting light uniformly. |
|
symmetric(al) 1 |
|
solid shape |
|
Divisible into essentially equal halves along one or more lines or planes. |
|
laevigate 1 |
|
relief |
|
Very smooth. |

STRUCTURE |
|
A small barbel (barbella); a very diminutive barb. |
|
mixed-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, some becoming indistinct before reaching it, others terminating there. |
|
cane |
< culm, stem |
STRUCTURE |
|
A woody, aboveground culm. Use of this term or culm instead of stem is a matter of tradition and preference, not of descriptive precision or necessity. |
|
one-sided 2 |
= unilateral |
orientation |
|
Disposed or directed toward one side only. |
|
colpate |
= fossulate, furrowed, grooved, sulcate, valleculate |
architecture |
|
Having one or more elongate, relatively narrow and shallow depressions (colpi). |
|
petiolar |
|
position |
|
Upon or otherwise directly associated with the petioles. |
|
pseudoterminal |
|
insertion |
|
Only apparently terminal; originally subapical but displaced toward the apex by differential growth during development. |
|
…colpate |
= …fossulate, …furrowed, …grooved, …sulcate, …valleculate |
architecture |
|
