dwarfed |
|
size |
plant |
Strongly reduced; unusually or unexpectedly very small throughout. |
|
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. |
|
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. |
|
rectangular |
|
plane shape |
|
Basically four-sided, the sides more or less straight, those of each opposing pair more or less parallel, the generalized angles between adjacent sides approximately 90°. |
|
suprafoliar |
|
insertion |
|
Upon the stems, each directly above (distal to) and very near a point of leaf insertion. |
|
viviparous |
|
reproduction |
|
Producing sexually or asexually generated offspring that begin growth and development while borne upon the parent plant. |
|
epirhizal |
|
insertion |
|
Upon or arising from the roots. |
|
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. |
|
rhizomatous |
|
architecture |
plant |
Having rhizomes. |
|
placentation |
|
CHARACTER |
|
Disposition of the placenta(e) within an ovary. |
|
tetrad scar |
|
FEATURE |
|
A surficial ridge or angle resulting from coherence with other spores produced from the same mother cell. |
|
cyathiate |
|
architecture |
inflorescence |
Comprising one or more cyathia. |
|
polygamodioecious |
|
reproduction |
taxon |
Basically dioecious but with some plants bearing some bisexual flowers. |
|
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. |
|
sapwood |
|
STRUCTURE |
|
That portion of the wood (xylem) of a stem or root whose cells are still living and functional; concentric about the heartwood once the latter has begun to form. |
|
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). |
|
stigma pl. stigmata, stigmas |
|
STRUCTURE |
|
An exposed, localized portion of a pistil that retains deposited pollen and stimulates its germination, the pollen tubes then growing through or along it toward the ovule(s). |
|
homogamous 2 |
|
reproduction |
plant, inflorescence |
Having flowers that do not differ in sexual constitution. |
|
true |
|
derivation |
indusium |
Constituting a distinct enation from the epidermis, not simply a marginal fold of the lamina as a whole. |
|
flange |
|
STRUCTURE |
|
A relatively broad, circumferential rim or ridge that protrudes laterally. |
