polyplicate |
|
architecture |
pollen grain |
Inaperturate with meridional folds, thus appearing longitudinally wrinkled. |
|
valvate 4 |
|
dehiscence |
fruit |
With longitudinal segments of the wall (valves) separating partly or wholly from one another, spreading outward from the base or apex, and sometimes falling away. |
|
free-central |
|
placentation |
|
Upon the free axial column of a compound, unilocular ovary. |
|
gum |
|
SUBSTANCE |
|
A highly viscous and sticky exudate that becomes more or less elastic and/or deformably solid upon drying. Overlaps conceptually with latex. |
|
canalicular |
|
insertion |
|
Upon or otherwise directly associated with the channel of a petiole or petiolule. |
|
flower |
|
STRUCTURE |
|
A functionally integrated, complex structure comprising sets of sporophytic and/or associated sterile structures disposed in standard sequence along a common axis; consisting of one or more constituent members each of, in ascending (proximal to distal) order of insertion, perianth (tepals, or else sepals and/or petals), androecium (stamens, staminodes and/or other associated structures), and/or gynoecium (pistils and/or other associated structures), the foregoing all borne laterally from the distal portion (receptacle) of the axis; depending upon the combination of structures present, may be bisexual, staminate only, pistillate only, or sterile; characteristic of and unique to the Magnoliophyta (Angiospermae). When a fertile androecium and gynoecium are both present a flower is termed perfect. When perfect and also with calyx and corolla both present, a flower is termed complete. Both terms are somewhat archaic and of limited descriptive value. |
|
zoned |
|
coloration |
|
Having two or more fairly distinctly delineated areas of contrasting hues and/or intensities. |
|
gummy |
|
texture |
|
Highly viscous and sticky, liquid or more or less deformably solid, sometimes more or less elastic. |
|
canalicular |
|
position |
|
Upon or otherwise directly associated with the channel of a petiole or petiolule. |
|
pubescent 1 (broad sense) |
|
pubescence |
|
Bearing trichomes. This is one of the most ambiguous terms in the botanical lexicon; it should not be used unless its intended meaning is explicit. |
|
glochidiate |
|
pubescence |
|
Bearing glochids (glochidia). |
|
resinous 2 |
|
texture |
|
Having the consistency of resin. |
|
intravaginal |
|
position |
|
Within the leaf sheath. |
|
inflorescence 2 |
|
STRUCTURE |
|
The basic architectural unit of the flower-producing portion of a plant; comprising one or more flowers, their associated supporting axes (peduncles, main axes, branches and pedicels), if any, and the appendages thereto (bracts, bractlets or bracteoles or prophylls, involucres, involucels, and glumes), if any; delimited by the insertion or gradation of a single peduncle, peduncle cluster, pedicel, pedicel cluster, or sessile flower, as the case may be, directly upon or into some proximal vegetative structure not of one of these types; depending upon the type(s) of flowers included, may be bisexual (all flowers bisexual), staminate (all flowers staminate), pistillate (all flowers pistillate), sterile (all flowers sterile), or mixed (two or more types of flowers present); most appropriately described using nominative terms. |
|
coloration |
|
CHARACTER |
|
Hue(s), intensity(ies), and/or pattern (if any) of coloring. When more than one hue and/or intensity is involved, a term describing the pattern of contrast will be applicable, and the description as a whole should be phrased to indicate the particular role of each in the pattern; e.g., "ovaries striate, yellow on green"; "petals pink, spotted yellow basally"; "sepals green, suffused with red". |
|
sepal |
|
STRUCTURE |
|
One of the one or more constituent members of a calyx; usually green and leaf-like, but sometimes with color and/or texture otherwise, sometimes petaloid; may be distinct or else connate with one or more others and/or may be free or else adnate to one or more other floral structures. |
|
knee 2 |
|
STRUCTURE |
|
An emergent portion of an otherwise normally submerged secondary root of a wetland tree, resembling a bent human knee. |
|
spathe |
|
STRUCTURE |
|
A usually relatively large, sometimes showy, foliose bract subtending and sometimes partially enclosing an inflorescence, esp. a spadicate one; in Liliidae (monocotyledons). |
|
acrocaulous |
|
position |
|
At or very near the stem tip. |
|
sinuate |
|
margin |
|
Having regular, curved, smoothly connected, alternating concavities and convexities. See also repand. |
|
cylindric(al) |
|
solid shape |
|
Solid and transversely round with a more or less uniform diameter, the ends blunt. |
|
manifestation |
|
CHARACTER |
|
Degree or nature of evidence when present within the context in point. |
|
naked 2 |
|
architecture |
bud |
Lacking enclosing protective scales, the outermost embryonic components exposed and not differing significantly from those within. See also perulate. |
|
dichasiate |
|
architecture |
inflorescence |
Comprising one or more simple or compound dichasia. See also cincinnate, cymose, cymulose, helicoid-cymose, monochasiate, scorpioid-cymose. |
|
surface |
|
FEATURE |
|
The exterior or bounding area or layer of any structure, regarded as being infinitely thin; usually described as to relief, reflectance, and/or vesture. |
