|
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. |
|
perennial 1 |
|
duration |
plant |
Normally living more than two years, with no definite limit to its life span. |
|
veinlet |
|
STRUCTURE |
|
A strand belonging to the ultimate (least in diameter) order of vasculature in a leaf or other basically laminar structure when that order consists of strands ending freely within areoles and/or connecting distally by pairs across areoles; absent in some taxa. See also costa (rib), lateral vein, midvein (midnerve, midrib), primary vein, secondary vein, tertiary vein, vein (nerve). |
|
embryotega pl. embryotegae, embryotegas |
|
STRUCTURE |
|
A small, hardened, lid-like portion of the testa (seed coat) at the micropyle of some seeds, detaching at germination. |
|
angular |
|
plane shape |
|
Having sides that meet at acute or obtuse angles. |
|
germination 1 |
|
CHARACTER |
|
The process wherein a dormant embryo resumes active metabolism and growth, the primary root and shoot emerging from the seed coat, the young sporophyte thereupon entering the seedling stage. |
