sawtooth |
|
STRUCTURE |
|
One of a series of regularly spaced, angular, marginal convexities oriented at an acute angle to the generalized perimeter of a laminar structure. See also sawtoothlet, scallop (crena), scalloplet (crenule), tooth, toothlet. |

|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
|
six-… |

prefix |
|
Indicating presence of or constitution by six entities of the type denoted by the term's stem; as in six-angled, six-sepaled, six-styled. |
|
granulose |

texture |
|
Composed of grain-like particles; loose, dry, and coarsely particulate. |
|
stipe 1 |

STRUCTURE |
|
A small, slender connection between a pollinium caudicle and a viscidium; in Orchidaceae. |
|
taeniate |
= tapeworm-shaped |
solid shape |
|
Slender, elongate, basically cylindric or compressed-cylindric with shallow, narrow, more or less regular constrictions along its length, the whole apparently segmented and straight or variously curved. |
|
lanuginose |
< cottony |
pubescence |
|
Bearing relatively long and fine, intertwined, somewhat matted, capillate trichomes. |
|
woody |
= ligneous |
texture |
|
Of or resembling wood (xylem). |
|
beak 2 |
= rostrum |
STRUCTURE |
|
The inner, horn-like segment of a coronal lobe; esp. in Asclepiadaceae. |
|
mound-shaped |
= cushion-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. |
|
carinate |
= keeled |
solid shape |
|
Having an elongate median longitudinal ridge that is basically triangular in transverse section, resembling the keel of a boat; esp. a leaf blade or sheath, glume, lemma, palea, sepal or petal. |
|
ovary |
|
STRUCTURE |
|
The proximal portion of a pistil (either simple or compound) within which the ovules are borne; usually of somewhat greater diameter and/or volume than the remainder of the pistil. |
|
complex |
|
architecture |
|
Comprising two or more basic structural entities, at least two of which are dissimilar. |
|
pinnatifid |
> pinnatisect; < pinnate |
plane shape |
|
Pinnately divided. |
|
cymbiform |
= boat-shaped, 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. |
|
punctate 2 |
= dotted |
relief |
|
Having small, round, shallow depressions or low protrusions. See also puncticulate (small-dotted). |
|
eccentric |
|
position |
|
Having a center or axis of symmetry not coincident with that of the context of reference. |
|
rough 1 |
= scabrous |
pubescence |
|
Of or bearing coarse, stiff, ascending, trichomes and markedly rough to the touch. |
|
fibrous |
|
texture |
|
Having tough, woody or sclerotic strands distributed through a softer matrix. |
|
sharp |
= acute |
apex |
|
Acutely angular; regularly and more or less straightly attenuate to an angular tip, the sides intersecting at an angle of less than 90°. |
|
fibrous root |
< diffuse root |
STRUCTURE |
|
A diffuse root that includes a significant component of woody or sclerotic strands and is consequently tough and often wiry. |
|
sheath (leaf) |
|
STRUCTURE |
|
The lower (basal or proximal), fundamentally laminar but strongly involute portion of one of the non-petiolate leaves characteristic of most monocotyledons (Liliidae); distinct from the leaf blade, which, when present, is borne distally upon it; analogous, though not necessarily homologous, with a petiole; usually more or less completely enclosing a portion of the stem above the node from which the leaf is borne. |
|
glabrescent |
= balding |
pubescence |
|
Becoming glabrous (bald, psilate) with age. |
|
stamen |
|
STRUCTURE |
|
A seed-plant organ that produces and releases pollen; usually comprising a stalk (filament) that bears a locular structure (anther) containing sporogenous tissue; however, the filament may be lacking and the anther sessile, or the stamen may be undifferentiated, the whole then consisting of microsporangia embedded in or borne upon the surface of a more or less planate body of sterile tissue; one of the constituent organs of a bisexual or a staminate flower; may be distinct or else connate with one or more others and/or may be free or else adnate with one or more other floral structures. |
|
suprafoliar |
|
position |
|
Upon the stems, each directly above (distal to) and very near a point of leaf insertion. |
