|
scrotiform |
= scrotum-shaped |
solid shape |
|
Saccate (bag-, pouch- or sack-shaped) and somewhat swollen bilaterally in the distal portion; like a scrotum. |
|
spheroid(al) |
= globose, globular, orbicular, rotund, spheric(al) |
solid shape |
|
Uniformly convex, circular in any median section and in outline when viewed from any angle; like a sphere or globe. |
|
strophiole |
= caruncle |
STRUCTURE |
|
An outgrowth from the seed coat (testa) around or near the hilum and micropyle, or from the raphe. |
|
infrabracteal |
|
position |
|
Upon the axis directly below a bract insertion. |
|
lepidote |
= squamose; < scaly |
pubescence |
|
Bearing lepides (squamae). See also squamellose. |
|
unilateral 3 |
= one-sided |
insertion |
|
Upon or arising from one side only of the bearing structure. |
|
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. |
|
approximate |
= close |
arrangement |
|
Disposed relatively near to one another. |
|
lodicule |
= squamella |
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. |
|
boat-shaped |
= cymbiform, navicular |
solid shape |
|
Like the generalized form of a boat hull, the walls relatively thin to moderately thick, the interior essentially empty and open along one side. |
|
centralium pl. centralia |
|
FEATURE |
|
A central longitudinal cavity within the seed; esp. in Arecaceae (Palmae). |
|
panniform |
< felted |
pubescence |
|
Of closely intertwined, capillate trichomes that form a dense, felt-like mat. See also pannose. |
|
pleated 2 |
= plaited, plicate |
vernation |
|
Having alternately adaxial and abaxial lengthwise folds, resembling a closed fan. |
|
derivation |
|
CHARACTER |
|
Ontogenetic origin. |
|
ensiform |
= sword-shaped |
solid shape |
|
Elongate and moderately slender, strongly compressed, the opposite faces plane, parallel, broadest at the base and gradually attenuate to a short, more strongly attenuate, acute apex; like a broadsword blade. |
|
sawtoothed |
= serrate |
margin |
|
Having regularly spaced, angular convexities oriented at an acute angle to the generalized perimeter. See also scalloped (crenate), small-scalloped (crenulate), small-sawtoothed (serrulate), small-toothed (denticulate), toothed (dentate). |
