ascidiform |

lateral structure |
Spreading at the base and then curving upward or forward, the distal portion more or less parallel to the bearing structure. |
articulation |

STRUCTURE |
|
A distinct, relatively narrow zone of demarcation between adjacent main portions of an elongate structure, often thicker than the rest of the structure and sometimes a site of eventual abscission. |
articulate(d) |
= jointed |
architecture |
|
Elongate with one or more distinct, relatively narrow zones of demarcation between adjacent main portions of the whole, these articulations (joints) often thicker and sometimes sites of eventual abscission. |
arrowhead-shaped 2 |
= sagittate |
plane shape |
|
Generally triangular, tapering gradually from the base to an acute apex, the base with a relatively large, acute, retrorse lobe to either side; like the outline of the broad lateral face of an arrowhead. |
arrowhead-shaped 1 |
= sagittate |
base |
laminar structure |
Having two retrorse, generally triangular lobes, one to either side. |
arrangement |
|
CHARACTER |
|
Disposition of equivalent structures with respect to one another (positions/insertions and/or orientations, regarded collectively) within some explicit or implicit standard context. Overlaps conceptually with habit, insertion, orientation, position, and shape. |
aromatic |
|
odor |
|
Having a distinct odor; usually restricted to pleasant odors. |
aristate 2 |
|
apex |
pappus scale |
Terminating in one or more awn- or bristle-like appendages. |
aristate 1 |
= awned, bristled |
apex |
|
Bearing one or more aristae (awns, bristles, setae). |
arista pl. aristae |
= awn, bristle, seta |
STRUCTURE |
|
A slender, more or less straight and stiff, fine-pointed, terminal or subterminal appendage or prolongation, sometimes a continuation of the bearing structure's central primary vein, as on a glume, lemma, or palea in Poaceae (Gramineae). |
arillus pl. arilli |
= aril (strict sense); < aril (broad sense) |
STRUCTURE |
|
An appendicular structure that wholly or partly envelops a seed and is an outgrowth from the funicle or raphe, and thus is ontogenetically derived from the placenta; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored. |
arillode |
< aril (broad sense) |
STRUCTURE |
|
A "false" aril; an appendicular structure that wholly or partly envelops a seed and is produced from or a modification of the outer integument or (in some Pinophyta) a subtending involucre, but not from the funicle or raphe, and thus is not ontogenetically derived from the placenta; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored. |
arillate |
|
architecture |
seed |
Having an aril. |
aril 2 (strict sense) |
= arillus |
STRUCTURE |
|
An appendicular structure that wholly or partly envelops a seed and is an outgrowth from the funicle or raphe, and thus is ontogenetically derived from the placenta; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored. |
aril 1 (broad sense) |
> arillode, arillus |
STRUCTURE |
|
An appendicular structure that wholly or partly envelops a seed and is produced from or a modification of the funicle, raphe, outer integument, or (in some Pinophyta) a subtending involucre; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored. |
areole 2 |
= areola |
STRUCTURE |
foliaceous structure |
Any distinguishable laminar portion bounded on all sides by anastomosing veins and not traversed or dissected by any vasculature other than veinlets. |
areole 1 |
= areola |
STRUCTURE |
|
Any distinctive surficial discontinuity of generally circular outline, whether concave, flush, or convex; when protuberant, sometimes bearing trichomes or spines, as in some Cactaceae. This term is used only when such entities are deemed structurally distinctive enough to merit description in their own rights, rather than as aspects of the surface. |
areolate |
|
relief |
|
Having numerous, small, irregularly disposed, transversely angular, shallow depressions or low protrusions overall. |
areola 2 pl. areolae |
= areole |
STRUCTURE |
foliaceous structure |
Any distinguishable laminar portion bounded on all sides by anastomosing veins and not traversed or dissected by any vasculature other than veinlets. |
areola 1 pl. areolae |
= areole |
STRUCTURE |
|
Any distinctive surficial discontinuity of generally circular outline, whether concave, flush, or convex; when protuberant, sometimes bearing trichomes or spines, as in some Cactaceae. This term is used only when such entities are deemed structurally distinctive enough to merit description in their own rights, rather than as aspects of the surface. |
arcuate 2 |
|
plane shape |
|
Elongate and more or less regularly curved from one end to the other, one side convex, the opposite concave. |
