radical |
|
position |
|
Upon, arising from, or otherwise directly associated with the root. |
collateral |
|
insertion |
buds |
In pairs within or immediately straddling the leaf axils, the members of a pair lateral to one another. |
fistulose |
|
solid shape |
|
Basically tubular with closed ends. |
symmetric(al) 2 |
|
architecture |
flower |
Having the perianth members in whorls that are actinomorphic and equal in number of members. |
spikeleted |
|
architecture |
inflorescence |
Having the penultimate subdivisional order consisting of spikelets. |
puberulent |
|
pubescence |
|
Finely pubescent in the restricted sense of that term. |
floret |
|
STRUCTURE |
|
A very small, structurally specialized flower, especially when occurring in capitulum (head; Asteraceae), or in a spikelet (Poaceae), where it includes the immediately subtending bracts (lemma and palea). |
aciculate |
|
coloration |
|
Having fine, irregularly oriented, straight streaks of contrasting hue and/or intensity. |
polygamomonoecious |
|
reproduction |
taxon |
Basically monoecious but with some or all plants bearing some bisexual flowers. |
superposed 2 |
|
insertion |
buds |
Axillary in pairs, one member of each pair directly above the other. |
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 ). |
indeterminate |
|
development |
|
Having the lateral (peripheral, basal, or proximal) portions differentiating first and the terminal (central, apical, or distal) portion later, development thus proceeding sequentially upward or inward. |
anther |
|
STRUCTURE |
|
The fertile, loculate, pollen-bearing portion of a stamen, containing one, two, or four thecae (pollen sacs), when that portion is differentiated from and borne at the summit of a narrower supporting stalk (filament), or when such differentiation is deemed to have occurred in the evolutionary past with subsequent reduction of the filament (the anther then sessile and constituting the entirety of the stamen). |
scape |
|
STRUCTURE |
|
A leafless, essentially naked, inflorescence-bearing stem (or peduncle) arising directly from a caudex or rhizome, its point of insertion slightly beneath, at, or slightly above the substrate surface. |
bulliform |
|
solid shape |
|
Resembling a blister; broad, relatively thin at the periphery, the lower surface approximately flat, the upper shallowly to strongly convex. |
prominence |
|
CHARACTER |
|
Elevation or depression of a discrete feature relative to the surrounding surface. |
obovate |
|
plane shape |
|
Inversely ovate (egg-shaped). |
aquatic |
|
habit |
plant |
Growing in water. |
leaf scar |
|
FEATURE |
|
A scar on a twig or stem due to abscission of a megaphyll; having an outline like that of a transverse section through the base of the petiole, sheath, or blade that was inserted there. |
persistent |
|
duration |
structure |
Remaining attached and conspicuous until the bearing structure reaches maturity. |
exsert(ed) |
|
position |
anther, style |
Protruding beyond the floral envelope. See also included. |
involucrate 1 |
|
architecture |
inflorescence |
Subtended by an involucre. |
woody-clumping |
|
habit |
plant |
Having or developing the character of a woody clump. See also arboreous, arborescent, bushy, frutescent, fruticose, shrubby, subshrubby, suffrutescent, suffruticose, tree-like. |
tertiary vein |
|
STRUCTURE |
|
A strand belonging to the third order of vasculature in a leaf or other basically laminar structure, except when that is the ultimate order (consisting of veinlets); branching from a primary or secondary vein. See also costa, lateral vein, primary vein, rib, secondary vein, veinlet. |
monadal |
|
arrangement |
pollen |
Shed singly, or essentially so, only loosely and irregularly, if at all, coherent, each original tetrad having separated fully. |
