limp |
|
texture |
|
Lacking stiffness in in one or more dimensions, thus drooping or sagging where unsupported. |
foliar |
|
position |
|
Upon or otherwise directly associated with the leaves. |
pneumatophore |
|
STRUCTURE |
|
A structurally and functionally specialized root serving as an aboveground aerating organ; found in some woody taxa of wet habitats, notably some mangroves. |
apex pl. apices |
|
CHARACTER |
|
Configuration of the uppermost, distal, or terminal portion of a structure, its extent determined somewhat subjectively in relation to the shape of the structure as a whole. The concept of apex varies from one descriptive context to another, since the apex is not a clearly delimited, morphologically distinct entity. The terms for describing apical condition are not strictly coordinate logically — some are more inclusive than others, some describe conditions involving what can be regarded as appendages, and some refer to the apex in a developmental as well as a strictly topological sense — and precise characterization may require using more than one descriptor. The semantic antecedent of some descriptors is "apex," whereas the antecedent of others is the structure as a whole (e.g., leaf ). |
summer annual |
|
nominative |
plant |
Annual, germinating in spring or early summer, reproducing sexually with no prolonged vegetative stage beforehand, and dying by late summer or autumn. See also winter annual. |
absent |
|
presence |
|
Not occurring within the context in point. |
prickly |
|
architecture |
|
Bearing prickles. |
heterocolpate |
|
architecture |
pollen grain |
Having long, narrow, regularly disposed lacunae (pseudocolpi). |
corymbose |
|
architecture |
inflorescence |
Comprising one or more corymbs. |
thyrse |
|
nominative |
inflorescence |
An elongate, indeterminate main axis bearing numerous lateral branches, each the principal axis of a cymose subdivision. |
papilla pl. papillae |
|
FEATURE |
|
A small, conoidal protrusion resembling a pimple. See also pustule (blister, bulla). |
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. |
axillary |
|
insertion |
|
Within the axil; nodal and at or very close to the vertex of the distal angle between a lateral structure, especially a leaf, and the axis that bears it. |
gum |
|
SUBSTANCE |
|
A highly viscous and sticky exudate that becomes more or less elastic and/or deformably solid upon drying. Overlaps conceptually with latex. |
secund 2 |
|
architecture |
stem |
Having the petioles oriented such that the main bodies of all the leaves lie to one side of the bearing stem. |
intruded |
|
placentation |
|
Upon partial septa excrescent from the wall of a compound, unilocular ovary. |
umbellate |
|
architecture |
inflorescence |
Comprising one or more umbels. |
symmetric(al) 1 |
|
plane shape |
|
Divisible into essentially equal halves along one or more lines or planes. |
campylotropous |
|
orientation |
ovule |
Having the (reniform) ovule curved toward the ovary wall, the micropyle facing the wall, and the funiculus attached near the center of the concave side, the curvature and displacement of funicular insertion due to asymmetrical growth during ontogenesis. |
disc 2 var. disk |
|
STRUCTURE |
|
Collectively, the disc florets of a capitulum (head), or the surface presented by them. |
circumcaulous |
|
position |
|
Upon and surrounding the stem. |
woody clump |
|
nominative |
plant |
An aggregate of woody main stems that arise from belowground organs derived from a single progenitor; the members of a clump are individually tree- or shrub-like and sometimes become physically separate over time. See also bush, frutex, shrub, subshrub, suffrutex, tree, undershrub. |
tepal |
|
STRUCTURE |
|
Any member of an undifferentiated perianth; may be green and foliaceous or colored and petaloid, distinct or else connate with one or more others, and/or free or else adnate with one or more other floral structures. |
brochidodromous |
|
venation |
|
Having a single median primary vein that branches to either side along its length, the secondary veins incurving strongly near but short of the margin, interconnecting serially, and forming a succession of marginal loops. |
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. |
