peduncle |

STRUCTURE |
|
The common stalk, when present, of a compound inflorescence or first-order subunit thereof, or of a solitary flower that is deemed to represent an evolutionarily reduced compound inflorescence. |
|
hypochilium |

STRUCTURE |
|
The proximal portion of a labellum (lip) that has distinct proximal, distal, and sometimes also central parts; in Orchidaceae. See also epichilium, mesochilium. |
|
drooping |

|
Erect to salient (patent, porrect, spreading) proximally and curving downward distally. |
|
cushion-shaped |
= mound-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. |
|
acrid 1 |
= pungent |
apex |
|
Terminating abruptly in a rigid, relatively short, sharp point composed of both vascular and laminar tissues. |
|
…gonous |
= …angled |
solid shape |
|
Elongate with the number of longitudinal angles indicated by the prefix, the intervening sides transversely straight to concave; as in hexagonous, trigonous. See also deltoid, …gonal (…angular), obdeltoid, triquetrous. |
|
ceraceous 1 |
= cereous, waxen, waxy; > caesious, glaucescent, glaucous, pruinose |
coating |
|
Covered with wax or a wax-like substance. |
|
pleated 2 |
= plaited, plicate |
vernation |
|
Having alternately adaxial and abaxial lengthwise folds, resembling a closed fan. |
|
axehead-shaped |
= dolabrate |
solid shape |
|
Like an axe head oriented cutting edge downward. |
|
lid |
= operculum |
STRUCTURE |
|
A distal, cover-like portion of a structure whose main body is otherwise closed, transversely discontinuous with the main body around most of the circumference, or becoming partially or wholly separate by transverse dehiscence; as of a pitcher (ascidium), pollen grain, pyxis, or spore case (sporangium). |
|
eucamptodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, the secondary veins upwardly arcuate, gradually becoming indistinct interior to the margin, and serially interconnected by cross-branches without formation of marginal loops. |
|
rostellate |
= small-beaked |
apex |
|
Diminutively rostrate (beaked). |
|
obovoid |
|
solid shape |
|
Inversely ovoid (egg-shaped). |
|
bract 2 (strict sense) |
|
STRUCTURE |
|
Any primary or first-order lateral structure ontogenetically and anatomically analogous with, and therefore presumably homologous with, but relatively smaller than, a leaf, especially when subtending an inflorescence, other reproductive structure, or portion thereof; putatively, an evolutionarily reduced leaf. |
|
hirtellous |
|
pubescence |
|
Finely hirsute. |
|
complex |
|
architecture |
|
Comprising two or more basic structural entities, at least two of which are dissimilar. |
|
pulvinate 2 |
= cushion-shaped, mound-shaped, 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. |
|
crisped |
= crispate, curly |
margin |
|
Having closely and irregularly spaced, irregularly shaped, often compound convexities that curve irregularly through three dimensions. |
|
megasporocarp |
= macrosporocarp (not recommended) |
STRUCTURE |
|
A sporocarp that bears only megasporangia. |
|
seedling |
|
PLANT |
|
A plant in the first stages of its growth following emergence from the seed. |
|
geniculate |
= kneed |
solid shape |
|
Elongate, abruptly bent, somewhat thicker at the angle, and appearing as though articulate like a leg at the knee. |
|
pappus pl. pappi |
|
STRUCTURE |
|
A set of one or more awns (aristae, bristles, setae) or scales at the summit of an inferior ovary just beneath or outside the free portion of the corolla; persisting in the fruit (cypsela) and often aiding wind or animal dispersal; in Asteraceae (Compositae). Considered by some to be an evolutionarily modified upper calyx portion, the lower portion having been incorporated into the floral tube casing adnate to the ovary wall; considered by others to be an outgrowth from the ovary wall. |
|
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. |
|
intercostal |
|
position |
|
Between the costae. |
|
suprabracteal |
|
insertion |
|
Upon the axes, each directly above (distal to) and very near a point of bract insertion. |
