|
receptacular |
|
position |
|
Upon, arising from, or otherwise directly associated with the receptacle. |
|
suprabasal |
|
insertion |
|
Just above the base of the structure in point. |
|
coronal |
|
position |
|
Upon or otherwise directly associated with the corona. |
|
knee 2 |
|
STRUCTURE |
|
An emergent portion of an otherwise normally submerged secondary root of a wetland tree, resembling a bent human knee. |
|
epiphyllous |
|
insertion |
|
Upon the leaves, or partially adnate thereto and apparently arising therefrom. |
|
muticous |
|
apex |
|
Lacking a distinct terminal point (when one might be expected). |
|
rhachis |
|
STRUCTURE |
|
See rachis. |
|
casing |
|
STRUCTURE |
|
The portion (if any) of a floral tube that is adnate to the gynoecium. See also collar, neck. |
|
nodulose |
|
solid shape |
|
Diminutively nodose; esp. roots of Fabaceae (Leguminosae), the nodules harboring nitrogen-fixing bacteria. |
|
pollinium pl. pollinia |
|
STRUCTURE |
|
A mass of coherent pollen grains disseminated as a unit by adhering to a pollinating insect, representing the entire content of a single theca or of fused thecae; often distally attenuate to a sterile caudicle (translator arm), which may attach to a viscidium, either directly or through an intervening stipe; esp. in Asclepiadaceae, Orchidaceae. |
|
square |
|
plane shape |
|
Equilaterally rectangular. |
|
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. |
