plated |
|
relief |
bark |
Fissured in a more or less regular, anastomosing pattern with distinct, relatively large, undisturbed sectors intervening, the latter ultimately falling away more or less intact after attaining considerable thickness. |
grumous |
|
solid shape |
|
Having an external aspect like a cluster of grains, basically convex overall. |
puberulent |
|
pubescence |
|
Finely pubescent in the restricted sense of that term. |
resin |
|
SUBSTANCE |
|
A substance of high molecular weight consisting of organic acids, esters, and/or terpenes, produced within plant tissue and exuded from wounds as a liquid that hardens to an amorphous glassy state upon exposure. |
herbaceous 1 |
|
habit |
plant |
Having no significant degree of secondary growth in any part of the shoot, which thus does not develop woody (lignified) tissue. |
raphe |
|
STRUCTURE |
|
That portion of the funicle adnate to the integument of an anatropous ovule; represented by a longitudinal ridge or other discontinuity in the surface and/or color of the testa on one side of the mature seed. |
hyponastic |
|
development |
laminar structure |
Having the abaxial surface differentiating and growing faster than the adaxial surface, thus, until maturity, development of the former more advanced than the latter at any given time and the structure as a whole involute or incurved. |
intravaginal |
|
insertion |
|
Within the leaf sheath. |
inflorescence 1 |
|
architecture |
|
Mode or progressive pattern of bearing flowers; most appropriately described using adjectival terms. |
knee 1 |
|
STRUCTURE |
|
An abrupt bend in an axial or other elongate structure. |
circumcaulous |
|
insertion |
|
Upon and surrounding the stem. |
ligule 4 |
|
STRUCTURE |
|
The distal, relatively flat portion of the zygomorphic corolla of a ligulate floret, terminating in 5 teeth or lobes; in Asteraceae (Compositae). |
continuous 1 |
|
architecture |
inflorescence |
Having the flowers or branch units distributed evenly along the axis, with no significant interruption. |
complete |
|
architecture |
flower |
Having all sets of basic floral structures (calyx and corolla, or else undifferentiated perianth; androecium; and gynoecium) present and functionally normal. |
mammose |
|
solid shape |
|
Having mammae. |
naked 1 |
|
architecture |
|
Lacking a covering that might have been expected. |
diaphragmed |
|
architecture |
pith |
Uninterrupted by cavities but heterogeneous in texture at axis maturity, with sectors of spongy tissue separated by relatively thin transverse plates of denser tissue that occur at the nodes or are otherwise regularly spaced along the axis. |
monochlamydeous |
|
architecture |
flower |
Having a monocyclic perianth. |
supramedial |
|
position |
|
Just above the middle of the structure in point. |
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. |
decurrent |
|
base |
laminar structure |
Having the lamina prolonged and adherent to the supporting axis beneath the point of vascular insertion, the prolonged portion termed a sterigma. |
oblong 2 |
|
solid shape |
|
Compressed-ellipsoid, the sides approximately parallel from near one end to near the other. See also ellipsoid(al). |
dorsiventral |
|
architecture |
|
Having structurally distinct abaxial (dorsal) and adaxial (ventral) portions or aspects. |
biennial 1 |
|
duration |
plant, stem |
Normally living two years; germinating or forming and growing vegetatively during one cycle of seasons, then reproducing sexually and dying during the following one. |
non-porous |
|
porosity |
|
Lacking vessels, the tracheary elements limited to tracheids and, sometimes, fiber-tracheids. |
