non-porous |
|
porosity |
|
Lacking vessels, the tracheary elements limited to tracheids and, sometimes, fiber-tracheids. |
|
chambered |
|
architecture |
pith |
Interrupted by cavities that are more or less regularly spaced along the axis and that result from disintegration of tissue prior to axis maturity. |
|
squarrose |
|
orientation |
lateral structure |
Having the proximal portion appressed and the distal portion deflexed, the latter more or less perpendicular to the surface of the bearing structure. |
|
obterete |
|
solid shape |
|
Inversely terete. |
|
samara |
|
nominative |
fruit |
Dry, indehiscent and having one or more integral alate portions that aid in aerial dispersal. |
|
toothlet |
|
STRUCTURE |
|
A diminutive tooth (dens). See also sawtooth, sawtoothlet, scallop (crena), scalloplet (crenule). |
|
deliquescent 1 |
|
architecture |
axis, laminar vein |
Branching laterally and repeatedly such that the initial axis loses its prominence over the length of the structure and seems to dissolve into the succesive orders of branches. See also excurrent. |
|
lineolate 2 |
|
relief |
|
Finely lineate, the depressions or protrusions short and often irregularly oriented. |
|
fixation |
|
CHARACTER |
|
Mode of attachment to a supporting structure. |
|
homochlamydeous |
|
architecture |
flower |
Having a perianth undifferentiated into distinct proximal and distal envelopes (calyx and corolla); composed of tepals, all essentially alike. |
|
scar |
|
FEATURE |
|
A discontinuity in surface color and/or relief due to abscission of a structure formerly borne there. |
|
diffuse |
|
architecture |
plant, stem |
Having branches remote and divergent to divaricate. |
|
flaccid |
|
texture |
|
Limp, sometimes appearing withered or shrunken. See also tumid (swollen, turgid). |
|
stilt root |
|
STRUCTURE |
|
A relatively stout or strong adventitious root arising from a woody stem branch and extending downward directly toward the substrate, within which it ultimately becomes anchored, thus supporting the branch of origin; as in some Ficus (Moraceae). |
|
cleistogamous |
|
reproduction |
flower |
Having the perianth remaining closed through anthesis, preventing deposit of pollen from other flowers, thus only self-pollination possible. |
|
bifacial |
|
architecture |
|
Having two opposite broad surfaces that differ distinctly in appearance. |
|
fluted |
|
solid shape |
|
Having rounded to angular longitudinal grooves. |
|
striped |
|
coloration |
|
Having one or more elongate, relatively narrow and, when multiple, more or less parallel, areas of contrasting hue and/or intensity. |
|
inferior 2 |
|
position |
ovary |
Wholly enclosed by a floral tube casing, the distal portions of the perianth and/or androecium thus arising from its apex. |
|
parietal |
|
placentation |
|
Upon the inner wall surface of a unilocular ovary, thus peripheral within the locule. |
|
alternate 2 |
|
arrangement |
structures in multiple whorls |
Having those of each whorl staggered radially in relation to those of the adjacent whorl(s). |
|
rachis 2 var. rhachis |
|
STRUCTURE |
|
A main or first-order axis of an inflorescence. |
|
subtending |
|
insertion |
|
Arising from the axis just below and very near to the base of some other specified lateral structure. This term is meaningless if the structure that is subtended is not indicated. |
|
connivent |
|
arrangement |
|
Converging and distally contiguous; esp. arcuate stamens with anthers contiguous. |
|
intricate |
|
arrangement |
|
Entangled; irregularly intertwined and not readily disentangled. |
