|
insertion |
|
Upon or otherwise directly associated with the vasculature. |
|
zygomorphic |
|
architecture |
perianth, calyx, corolla |
Bilaterally symmetric; divisible into two essentially equal portions along only one median logitudinal plane. |
|
epipetalous |
|
insertion |
|
Upon the petals, or partially adnate thereto and apparently arising therefrom. |
|
latrorse |
|
dehiscence |
anther |
Opening laterally, on the tangential sides. See also extrorse, introrse. |
|
oblique 2 |
|
orientation |
planate lateral structure |
Lying in a plane not coincident with the one defined by its longitudinal axis and that of the bearing structure. |
|
heterotrophic |
|
nutrition |
plant |
Dependent upon other organisms for some or all of its essential nourishment, assimilating such materials either directly from the other organisms, living or dead, or from their products. |
|
corolla tube 2 |
|
STRUCTURE |
|
The portion of the corolla of a bisexual or staminate disc floret proximal to the level of filament insertion; in Asteraceae (Compositae). |
|
throat 2 |
|
STRUCTURE |
|
The fully connate portion of the limb of a disc floret, proximal to the lobes (distinct distal portions of the petals); in Asteraceae (Compositae). |
|
intricate |
|
arrangement |
|
Entangled; irregularly intertwined and not readily disentangled. |
|
amplexicaul |
|
architecture |
foliaceous structure |
See amplexicaulous. |
|
ridged |
|
solid shape |
|
Having one or more ridges; esp. fruits of Apiaceae (Umbelliferae). |
|
tubercle |
|
FEATURE |
|
A small, rounded, knot-like swelling or wart-like protrusion. |
|
tree |
|
nominative |
plant |
Perennial, woody, more or less erect, relatively tall, with one or more distinct aboveground portions each with a single, relatively stout, columnar, main stem (trunk or bole) that bears branches. See also bush, frutex, shrub, subshrub, suffrutex, undershrub, woody clump. |
|
multiciliate |
|
architecture |
|
Having several to many cilia. |
|
knee root |
|
STRUCTURE |
|
A specialized secondary root of a wetland tree, a portion of which projects above mean water level and appears to bend as a leg does at the knee, its distalmost portion being anchored in the substrate beneath the water. The knee of the root is commonly regarded as a conduit for gas exchange between root interior and atmosphere, a function whose need is posited on the basis of the highly anaerobic and saturated conditions prevailing in wetland substrates. |
|
subsidiary cell |
|
STRUCTURE |
|
One of the cytologically distinctive epidermal cells that are sometimes present in a stomate and that surround and are regularly oriented in relation to the guard cells. |
|
asymmetric(al) 1 |
|
solid shape |
|
Not divisible into essentially equal halves along any line or plane. |
|
cupule |
|
STRUCTURE |
|
A cup-like structure inserted at the base of a fruit, partially enclosing it or not; composed of a persistent, usually dried, sometimes hardened involucre, perianth, or portion thereof, the constituent parts often coalescent, yielding a unitary structure. |
|
oblanceolate |
|
plane shape |
|
Inversely lanceolate (lancehead-shaped). |
|
infrapetiolar |
|
insertion |
bud |
Axillary and surrounded by the petiole base at maturity. |
|
synanthous |
|
maturation |
non-floral structure |
Maturing at the same time as the flowers. See also coetaneous. |
