A structure that resembles a stem but is not part of the axial system of a shoot, lacking anatomical differentiation into nodes and internodes. |
|
lenticular 2 |
= biconvex, lens-shaped |
solid shape |
|
Relatively thin with two round, convex, opposite broad faces intersecting acutely at the circumferential edge; like a double-convex lens. See also disciform (discoid), meniscoid. |

|
scutate |
= buckler-shaped, scutiform |
solid shape |
|
Relatively thin with opposite broad oblong faces, planate to shallowly concave-convex, sometimes thickened about the periphery such that each face has a marginal rim; like an oblong shield. See also scutellate (platter-shaped, scutelliform), which is not clearly distinct in its application. |
|
…colpate |
= …fossulate, …furrowed, …grooved, …sulcate, …valleculate |
architecture |

|
infrafoliar |
|
position |
|
Upon the stem directly below a leaf insertion. |
|
superaxillary |
|
insertion |
|
Internodal but close to and directly above the axil(s). |
|
endophytic |
|
habit |
|
Growing within some portion of another, unrelated, living plant. |
|
reproduction |
|
CHARACTER |
|
Type, morphology, disposition, function and/or dissemination of reproductive structures. |
|
ampulliform |
= flask-shaped, 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. |
|
nerve |
= vein; > costa, midnerve , midrib, midvein, rib |
STRUCTURE |
|
A strand belonging to any except the ultimate (least in diameter) order of vasculature in a leaf or other foliaceous structure. See also lateral vein, primary vein, secondary vein, tertiary vein, veinlet. |
|
sinus pl. sinus, sinuses |
|
FEATURE |
|
The space, indentation, or invagination (or, for some descriptive purposes, the outline thereof) between and delimiting any two consecutive or adjacent lobes or teeth of a structure. |
|
hastate 2 |
= halberd-head-shaped |
plane shape |
|
Basically triangular with an acute apex and two large, widely divergent basal lobes, each generally triangular and distally acute; like the stylized outline of the broad lateral face of a halberd head. |
|
crateriform |
= goblet-shaped |
solid shape |
|
Having a distal, concave, relatively thin-walled, basically hemispherical portion surmounting a much narrower, transversely round, pedestal-like base. |
|
phyllodium pl. phyllodia |
= phyllode |
STRUCTURE |
|
A leaf deemed to consist entirely or almost entirely of tissues evolutionarily derived from the petiole, all or a distal portion of which has become laminar, the original blade reduced to the point of absence or vestigiality. |
|
chaff 1 |
|
STRUCTURE |
|
Collectively, the paleae (pales, palets) sometimes borne on the receptacle of a capitulum (head) in Asteraceae (Compositae). |
|
lanceoloid |
= lancehead-shaped, lanciform |
solid shape |
|
Considerably longer than broad, compressed or not, broadest near the base and somewhat concavely attenuate to the apex, the attenuation in all median longitudinal planes or else largely confined to one, depending upon the extent of compression, if any. See also oblanceoloid (oblanciform). |
|
three-… |
= tri… |
prefix |
|
Indicating presence of or constitution by three entities of the type denoted by the term's stem; as in three-cleft, three-flowered, three-ranked. See also thrice… (tri…, triple…). |
|
felted |
> panniform, pannose |
pubescence |
|
Of or bearing closely intertwined, capillate trichomes that form a dense, felt-like mat. |
|
scabrate |
= rough, scabrid, scabridous, scabrous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
|
claw |
= unguis |
STRUCTURE |
|
The abruptly much narrower proximal portion, when present, of a laminar structure, esp. a petal; of variable shape itself, but usually attenuate toward the base. |
|
osseous |
= bony |
texture |
|
Very hard and rather brittle, like bone. |
