barbellule |
= barbellula |
STRUCTURE |
|
A small barbel (barbella); a very diminutive barb. |
|
simple 1 |

architecture |
|
Externally unitary and comprising only one basic morphological unit; not compound in either sense of that term. |
|
kneed |
= geniculate |
solid shape |
|
Elongate, abruptly bent, somewhat thicker at the angle, and appearing as though articulate like a leg at the knee. |
|
petiolar |
|
insertion |
|
Upon or otherwise directly associated with the petioles. |
|
mucronate |
|
apex |
|
Terminating abruptly in a short, hard point that is a continuation of vascular tissue. See also apiculate, mucronulate. |
|
equitant |
|
arrangement |
|
Alternate, distichous, basal, and congested, each conduplicate with its lateral edges overlapping and/or overlapped by those of the immediately adjacent one(s). |
|
fringe |
= fimbria |
STRUCTURE |
|
A marginal series or cycle of regular, slender, closely adjacent, more or less flexible segments or protrusions, when treated as an aggregate structure. |
|
squamella 3 pl. squamellae |
= lodicule, squamule |
STRUCTURE |
|
One of two or three small, scale-like structures inserted at the base of the androecium, distal to the palea, in most grass (Poaceae) flowers; often regarded as a vestigial branch or perianth member. |
|
acicular 2 |
= acerose, needle-shaped |
solid shape |
|
Rounded in cross-section and very slenderly elongate, broadest near the middle, and gradually attenuate to an acute apex and a slightly blunter base; like a needle. |
|
collar 1 |
|
STRUCTURE |
|
The free portion (if any) of a floral tube, distal to its casing and/or neck when one or both is/are present. |
|
lineate 2 |
> streaked, striate |
relief |
|
Having very narrow, straight, shallow depressions or low protrusions. See also lineolate. |
|
presence |
|
CHARACTER |
|
Occurrence within the context in point. |
|
disc floret |
|
STRUCTURE |
|
A floret that has an actinomorphic corolla, is bisexual, functionally staminate, or functionally pistillate, and is borne in a radiate, discoid, disciform, or radiant capitulum (head) interior (distal) to any peripheral series of differing florets that may be present; in Asteraceae (Compositae). |
|
architecture |
|
CHARACTER |
|
Composite structural configuration as to type, orientation, symmetry, insertion, position, fusion, presence, number, relative size, shape, texture, differentiation, and/or derivation of components and features. Overlaps conceptually with habit. |
|
turnip-shaped |
= napiform |
solid shape |
|
Depressed-globose overall and strongly concave-tapered (acuminate) at the base; like the generalized form of a turnip. |
|
flagellum pl. flagella |
|
STRUCTURE |
|
A very slender whip-like structure that extends from the main body of an antherozoid and, by active undulation, propels the cell through a liquid medium. |
|
…serrate |
= …-sawtoothed |
margin |
|
Having the number of orders of sawteeth indicated by the prefix, one upon another; as in biserrate. See also …crenate (…-scalloped), …dentate (…-toothed). |
|
cane |
< culm, stem |
STRUCTURE |
|
A woody, aboveground culm. Use of this term or culm instead of stem is a matter of tradition and preference, not of descriptive precision or necessity. |
|
penta… |
= five-… |
prefix |
|
Indicating presence of or constitution by five entities of the type denoted by the term's stem; as in pentandrous, pentacarpellate, pentacolporate. |
|
suberous |
= corky |
texture |
|
Firm, relatively light, discontinuous but strongly cohesive, and resilient. |
|
microsporocarp |
|
STRUCTURE |
|
A sporocarp that bears only microsporangia. |
|
cushion-shaped |
= mound-shaped, pulvinate, pulviniform |
solid shape |
|
Essentially round in transverse section, much broader than long or high, with a convex distal face that intersects either a more or less plane proximal face or, when the structure is sessile, its bearing surface. |
|
raised |
> prominent, prominulous |
prominence |
|
Protruding above the general level of the surrounding surface. |
|
entire |
|
margin |
|
Uninterrupted; not deviating significantly from its general line, thus lacking any localized convexities or concavities. |
|
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). |
