nectar |
|
SUBSTANCE |
|
An aqueous exudate of high sugar content. |
|
nectariferous |
|
exudation |
|
Producing and secreting nectar; when glands are nectariferous, they are usually indicated nominatively as nectaries. |
|
nectary |
< gland |
STRUCTURE |
|
A multicellular, anatomically distinct structure that produces and exudes nectar. |
|
needle |
< leaf, macrophyll (not recommended), megaphyll |
STRUCTURE |
|
A relatively stiff, compressed-acerose leaf; in Pinophyta. |
|
needle-shaped |
= acerose, acicular |
solid shape |
|
Rounded in cross-section and very slenderly elongate, broadest near the middle, and gradually attenuate to an acute apex and a slightly blunter base. |
|
neotenous |
|
maturation |
structure |
Retaining at maturity attributes that are usually restricted to the juvenile stage. |
|
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. |
|
net-like |
= anastomosing, netted, reticulate |
architecture |
tertiary and higher-order laminar veins, excl veinlets |
Interconnecting more or less regularly. |
|
netted 1 |
= anastomosing, net-like, reticulate |
architecture |
tertiary and higher-order laminar veins, excl veinlets |
Interconnecting more or less regularly. |
|
netted 2 |
= reticulate |
coloration |
|
Having a pattern of interconnected fine lines of contrasting hue and/or intensity. |
|
netted 3 |
= reticulate |
relief |
|
Having prominulous, more or less regularly interconnected lines. |
|
neuter |
|
architecture |
flower, floret |
Lacking both stamens and pistils. |
|
night-blooming |
= nocturnal |
habit |
flower |
Opening during the nighttime. |
|
nine-… |
= ennea… |
prefix |
|
Indicating presence of or constitution by nine entities of the type denoted by the term's stem; as in nine-carpelled, nine-loculed, nine-tepaled. |
|
nocturnal |
= night-blooming |
habit |
flower |
Opening during the nighttime. |
|
nodal |
> interpetiolar |
insertion |
|
Upon or associated with the nodes. |
|
nodal |
> interpetiolar |
position |
|
Upon or associated with the nodes. |
|
nodding |
= cernuous, nutant |
orientation |
stalked structure |
Having the stalk proximally erect and distally recurved, the main body thus oriented outward to downward. See also hanging (pendent, pendulous). |
|
node |
|
STRUCTURE |
|
One of the evident sectors of a stem that occur sequentially along its length and from which leaves (megaphylls) and lateral branches arise exogenously. The anatomy of nodes differs from, but is not abruptly distinct longitudinally from, that of the intervening sectors (internodes), with which it is smoothly confluent and from which is distinguished by the lateral transit and egress of vascular traces interconnecting the stem and the leaves and branches that it bears. |
|
nodiform |
= gongylodate, gongyloid, knob-shaped, knot-shaped |
solid shape |
|
Approximately globose, the surface convoluted or not, like a knob or knot; usually applied only to structures or components that are relatively small. |
|
nodose |
= knobby, knotty |
solid shape |
|
Having nodiform (gongylodate, gongyloid, knob-shaped, knot-shaped) protrusions. See also nodulose. |
|
nodule |
|
STRUCTURE |
|
A small nodiform (gongylodate, gongyloid, knob-shaped, knot-shaped) segment or protrusion; esp. in roots of Fabaceae (Leguminosae) and harboring nitrogen-fixing bacteria. |
|
nodulose |
|
solid shape |
|
Diminutively nodose; esp. roots of Fabaceae (Leguminosae), the nodules harboring nitrogen-fixing bacteria. |
|
non-porous |
|
porosity |
|
Lacking vessels, the tracheary elements limited to tracheids and, sometimes, fiber-tracheids. |
|
non-septate |
|
architecture |
trichome |
Lacking transverse inter- or intracellular septa or partitions. |
