dwarfed |
|
size |
plant |
Strongly reduced; unusually or unexpectedly very small throughout. |
|
reproduction |
|
CHARACTER |
|
Type, morphology, disposition, function and/or dissemination of reproductive structures. |
|
symmetric(al) 1 |
|
plane shape |
|
Divisible into essentially equal halves along one or more lines or planes. |
|
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). |
|
contiguous |
|
arrangement |
|
Touching one another. |
|
involucel |
|
STRUCTURE |
|
One or more closely proximate whorls of bractlets (bracteoles, prophylls) immediately subtending (below or outside) a subordinate portion of an inflorescence that is subtended as a whole by an involucre, the bractlets often leaf-like, sometimes petaloid. |
|
perfoliate |
|
architecture |
foliaceous structure |
Having a sessile lamina (blade) that uninterruptedly encircles the bearing axis, which thus passes through it at some point within the margin. See also amplexicaulous, connate-perfoliate. |
|
enation |
|
STRUCTURE |
|
A relatively small outgrowth from an otherwise regular boundary or surface of a larger structure. |
|
tepal |
|
STRUCTURE |
|
Any member of an undifferentiated perianth; may be green and foliaceous or colored and petaloid, distinct or else connate with one or more others, and/or free or else adnate with one or more other floral structures. |
|
spur 1 |
|
STRUCTURE |
|
A hollow protrusion from a calyx or corolla, often nectariferous. |
|
gibbous |
|
solid shape |
|
Bulging unilaterally near the base. |
|
monochasium pl. monochasia |
|
nominative |
inflorescence |
Determinate and falsely dichotomous with each axial segment bearing a single, sessile terminal flower; presumably derived from a dichasium by loss of the lateral flowers. See also cincinnus, cyme, cymule, dichasium, helicoid cyme, scorpioid cyme. |
|
epirhizal |
|
insertion |
|
Upon or arising from the roots. |
|
throat 2 |
|
STRUCTURE |
|
The fully connate portion of the limb of a disc floret, proximal to the lobes (distinct distal portions of the petals); in Asteraceae (Compositae). |
|
apiculum 1 pl. apicula |
|
STRUCTURE |
|
A short, slender, angular tip that is not notably harder or stiffer than the main body of the bearing structure. See also mucro. |
|
placentation |
|
CHARACTER |
|
Disposition of the placenta(e) within an ovary. |
|
tree |
|
nominative |
plant |
Perennial, woody, more or less erect, relatively tall, with one or more distinct aboveground portions each with a single, relatively stout, columnar, main stem (trunk or bole) that bears branches. See also bush, frutex, shrub, subshrub, suffrutex, undershrub, woody clump. |
|
cyathiate |
|
architecture |
inflorescence |
Comprising one or more cyathia. |
|
polygamodioecious |
|
reproduction |
taxon |
Basically dioecious but with some plants bearing some bisexual flowers. |
|
secondary root |
|
STRUCTURE |
|
Any root branch that originates directly or indirectly from a primary root. |
|
hemiparasitic |
|
nutrition |
plant |
Partially parasitic; facultatively heterotrophic to a limited degree and capable of obtaining a portion of its essential nourishment directly from other living organisms, to which no reciprocal benefit accrues. |
|
pseudobulb |
|
STRUCTURE |
|
An enlarged internode of an aboveground stem, storing water and photosynthate, resembling a bulb; esp. in Orchidaceae. |
|
lip cell |
|
STRUCTURE |
|
Either of a pair of adjacent, narrow, transversely oriented, thick-walled cells bordering the pore (stomium) of a sporangium. |
|
proliferous |
|
reproduction |
plant, structure |
Bearing plantlets, as from the leaf margin in some Kalanchoë (Crassulaceae). |
|
homogamous 2 |
|
reproduction |
plant, inflorescence |
Having flowers that do not differ in sexual constitution. |
