orientation |
anther |
Oppositely parallel to the filament on the adaxial side of the latter. |
|
isopetalous |
|
architecture |
flower, perianth, corolla |
Having the petals essentially alike in size and shape. |
|
latex pl. latices, latexes |
|
SUBSTANCE |
|
A moderately viscous and sticky exudate, often milky, sometimes otherwise colored or clear. Overlaps conceptually with gum. |
|
spikelet |
|
nominative |
inflorescence |
A compound structure belonging to the penultimate subdivisional order of a sedge or grass inflorescence; consisting of one or more florets (each a diminutive flower subtended by specialized bractlets (bracteoles) called scales or glumes in sedges, lemma and palea in grasses), spicately arranged along a common axis (rachilla), the axis and florets together subtended by one or (usually) two bracts (first and second glumes). The spikelet is usually considered to be the basic unit of inflorescence in Cyperaceae and Poaceae (Gramineae). |
|
spikeleted |
|
architecture |
inflorescence |
Having the penultimate subdivisional order consisting of spikelets. |
|
staminate |
|
architecture |
inflorescence, flower, floret |
Having functional stamens but no functional pistils, thus unisexual and male. |
|
anthela pl. anthelae |
|
nominative |
inflorescence |
A cyme with the main axis markedly shorter than the lateral axes, appearing generally paniculate when compound; esp. in Juncaceae. |
|
colporate |
|
architecture |
pollen grain |
Having one or more elongate, relatively narrow and shallow depressions (colpi), each containing a pore. |
|
dimidiate |
|
plane shape |
|
Halved, figuratively; bilaterally asymmetric, nearly or wholly lacking one side as implicitly compared with some corresponding bilaterally symmetric structure, real or imagined. |
|
androecial tube |
|
STRUCTURE |
|
The tubular portion of an androecium in which the component structures have fused with one another laterally over part or all their lengths. |
|
craspedodromous, mixed- |
|
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. |
|
embryo |
|
STRUCTURE |
|
The rudimentary spermatophyte contained within a viable seed. |
|
determinate |
|
development |
|
Having the terminal (central, apical, or distal) portion differentiating first and the lateral (peripheral, basal, or proximal) portions later, development thus proceeding sequentially downward or outward, growth of the whole thereby organizationally limited. |
|
calyx pl. calyces |
|
STRUCTURE |
|
Collectively, the sepals of a flower, whether distinct or connate; the outer or proximal envelope of a differentiated perianth, whether the other envelope (corolla) is also actually present or is deemed to be secondarily absent due to evolutionary reduction. |
|
dwarfed |
|
size |
plant |
Strongly reduced; unusually or unexpectedly very small throughout. |
|
appressed |
|
orientation |
lateral structure |
Angled at or near the base and closely flattened against the surface of the bearing structure, thus more or less parallel to it. |
|
base |
|
CHARACTER |
|
Configuration of the lowermost or proximal portion of a structure, its extent determined somewhat subjectively in relation to the shape of the structure as a whole. The concept of base varies from one descriptive context to another, since the base is not a clearly delimited, morphologically distinct entity. The terms for describing basal condition are not strictly coordinate logically — some are more inclusive than others, and some describe conditions involving what can be regarded as appendages — and precise characterization may require using more than one descriptor. The semantic antecedent of some descriptors is "base," whereas the antecedent of others is the structure as a whole (e.g., leaf ). |
|
centralium pl. centralia |
|
FEATURE |
|
A central longitudinal cavity within the seed; esp. in Arecaceae (Palmae). |
|
umbellate |
|
architecture |
inflorescence |
Comprising one or more umbels. |
|
cryptocotyloid |
|
germination |
seed |
Having the cotyledon(s) remaining inside the seed coat. |
|
…ternate |
|
architecture |
foliaceous structure |
Compound with the number of orders of leaflets indicated by the prefix, each order ternate; as in biternate, thrice-ternate. |
|
epipetalous |
|
position |
|
Upon the petals, or partially adnate thereto and apparently arising therefrom. |
|
perforate |
|
architecture |
foliaceous structure |
Having portions of the laminar (blade) area naturally devoid of any tissue. |
