|
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. |

|
Disposed relatively near to one another. |
|
boat-shaped |

|
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). |
|
flask-shaped |
= ampulliform, lageniform |
solid shape |
|
Generally circular in cross-section, broadest at or below the middle, approximately globose below that and constricted above to a relatively narrow neck; like a flask. |
|
size |
|
CHARACTER |
|
Nature as to absolute or comparative extent in any one dimension or in area or volume. |
|
greasy 1 |
= oily, oleaginous, unctuous |
coating |
|
Of a grease- or oil-like film. |
|
stipe 2 (broad sense, not recommended) |
< stalk; > gynophore, hypogynium, peduncle, petiole |
STRUCTURE |
|
A stalk of or supporting a frond, inflorescence, or gynoecium. |
|
lanulose |
|
pubescence |
|
Finely lanate. |
|
mucilage |
|
substance |
|
A slimy exudate. |
|
beaked |
= rostrate |
apex |
|
Terminating in a relatively long, tapering, more or less rigid point. See also small-beaked (rostellate). |
|
cariniform |
= keel-shaped |
solid shape |
|
Elongate, basically triangular in transverse section, tapering at one or both ends, the outer edge thus somewhat arcuate, the whole resembling the keel of a boat. |
|
ovate |
= egg-shaped |
plane shape |
|
Elongate and wholly convex, widest near a bluntly rounded base and attenuate to a narrower rounded apex; like the lateral outline of a fowl egg. See also obovate. |
|
composite |
= compound |
architecture |
|
Unitary as a whole but comprising two or more equivalent substructural entities, these topologically distinct (e.g., leaflets in a compound leaf) or not (e.g., carpels in a compound pistil). |
|
pinnatifid |
> pinnatisect; < pinnate |
solid shape |
|
Pinnately divided. |
|
puncticulate |
= small-dotted |
coloration |
|
Finely punctate (dotted). |
