|
subtending |
|
position |
|
Arising from the axis just below and very near to the base of some other specified lateral structure. This term is meaningless if the structure that is subtended is not indicated. |
|
abortive |
|
maturation |
spore, pollen, seed |
Never attaining functional maturity due to defective or arrested development. |
|
diplecolobal |
|
arrangement |
cotyledons |
Incumbent but with the cotyledons folded together twice or more, the folds transverse. |
|
muriculate |
|
relief |
|
Finely muricate. |
|
syncolporate |
|
architecture |
pollen grain |
Syncolpate, each groove containing a pore. |
|
emergent |
|
location |
plant, structure of aquatic plant |
Rising from beneath the water surface to a point above it. |
|
odorless |
|
odor |
|
Lacking a distinct odor. |
|
suprabracteal |
|
insertion |
|
Upon the axes, each directly above (distal to) and very near a point of bract insertion. |
|
tiller |
|
STRUCTURE |
|
An erect or ascending stem that branches from the base of another at or below the surface of the ground; esp. in Poaceae (Gramineae) and other monocotyledons (Liliidae). |
|
excurrent |
|
architecture |
axis, laminar vein |
Branching laterally such that the initial axis retains its prominence over the length of the structure, the succesive orders of branches relatively smaller. See also deliquescent. |
|
paniculate |
|
architecture |
inflorescence |
Comprising one or more panicles. |
|
umbilicate |
|
solid shape |
|
Having a relatively small, transversely round, central depression in an essentially round broad face. |
|
epiphytic |
|
habit |
plant |
Physically supported in its entirety by another plant through all or the major part of its life. |
|
tuberous 1 |
|
architecture |
plant |
Bearing tubers. |
|
perianth tube |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a syntepalous (gamotepalous) perianth proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the tepals. |
|
pollinarium pl. pollinaria |
|
STRUCTURE |
|
A pollinium together with, when present, its stipe and viscidium; the entire unit of pollinium dispersal. |
|
V-form |
|
arrangement |
bundle scars |
Disposed in an open-ended triangular pattern, like the letter V. |
|
pseudomonadal |
|
arrangement |
pollen |
Apparently monadal but each grain actually comprising an unseparated original tetrad in which the contiguous walls between component grains have dissolved. |
|
bottom-rooted |
|
habit |
plant |
Aquatic and rooted in the substrate beneath the water. |
|
ramal |
|
position |
|
Upon or otherwise directly associated with the stem branches. |
|
rhytidomal |
|
insertion |
|
Within, upon, or otherwise directly associated with the bark. |
|
bulbel |
|
STRUCTURE |
|
A comparatively small bulb branching laterally from a larger, currently primary one. |
|
integumentary |
|
derivation |
aril |
Produced from or a modification of one or both seed integuments. |
|
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 ). |
