prefix |
|
Indicating presence of or constitution by nine entities of the type denoted by the term's stem; as in nine-carpelled, nine-loculed, nine-tepaled. |
|
lancehead-shaped 1 |
= lanceolate |
plane shape |
|
Elongate, moderately narrow, broadest just above the base and gradually attenuate toward the apex, the sides more or less straight; like the outline of the broad lateral face of a lance head. See also oblanceolate. |
|
subapical |
= subterminal |
position |
|
Lateral and just below the apex. |
|
foveolate |
= fine-pitted, scrobiculate |
relief |
|
Finely foveate (pitted). |
|
cirrhous |
|
apex |
|
Having a narrow spiral tip that is a continuation of the central primary vein. |
|
auricle |
= ear |
STRUCTURE |
|
A small, rounded, lateral lobe at the base of a laminar structure, lying in more or less the same plane as the remainder of the lamina. |
|
zoned |
|
coloration |
|
Having two or more fairly distinctly delineated areas of contrasting hues and/or intensities. |
|
round |
= orbiculate, orbicular misapplied |
plane shape |
|
Circular. |
|
horn |
= corniculum |
STRUCTURE |
|
A straight or curved, slenderly conic or conoidal protrusion or terminal portion that resembles an animal horn. |
|
muscariform |
= broom-shaped, penicillate |
solid shape |
|
Having a proximal axis that bears a distal cluster of elongate slender branches or appendages, these variously ascending to erect; like a broom. |
|
bristly |
> hispid, setose |
pubescence |
|
Of or bearing relatively long and slender, more or less straight, terete, fine-pointed, stiff trichomes. |
|
calyx pl. calyces |
|
STRUCTURE |
|
Collectively, the sepals of a flower, whether distinct or connate; the outer or proximal envelope of a differentiated perianth, whether the other envelope (corolla) is also actually present or is deemed to be secondarily absent due to evolutionary reduction. |
|
pappus scale |
|
STRUCTURE |
|
A pappus element that is more or less planate and relatively thin and broad; may terminate in one or more awn- or bristle-like appendages. |
|
tetrad scar |
|
FEATURE |
|
A surficial ridge or angle resulting from coherence with other spores produced from the same mother cell. |
|
macrosporangium pl. macrosporangia (not recommended) |
= megasporangium |
STRUCTURE |
|
A sporangium that produces megaspores. |
|
receptacular |
|
position |
|
Upon, arising from, or otherwise directly associated with the receptacle. |
|
knee root |
|
STRUCTURE |
|
A specialized secondary root of a wetland tree, a portion of which projects above mean water level and appears to bend as a leg does at the knee, its distalmost portion being anchored in the substrate beneath the water. The knee of the root is commonly regarded as a conduit for gas exchange between root interior and atmosphere, a function whose need is posited on the basis of the highly anaerobic and saturated conditions prevailing in wetland substrates. |
|
stoma 1 (broad sense) pl. stomata |
= stomatal apparatus, stomate |
STRUCTURE |
|
A localized functional epidermal unit consisting of a microscopic pore and two encircling specialized cells, the guard cells, which, through changes of turgor pressure in response to environmental conditions, regulate the size of the pore and thus the rates of transpiration and gas exchange through it; the whole surrounded or not by associated, cytologically distinctive epidermal cells, the subsidiary or accessory cells, which, when present, are regularly oriented in relation to it. |
|
floral |
|
insertion |
|
Upon, within, or associated with the flowers. |
|
rhytidomal |
|
position |
|
Within, upon, or otherwise directly associated with the bark. |
|
unguis pl. ungues |
= claw |
STRUCTURE |
|
The abruptly much narrower proximal portion, when present, of a laminar structure, esp. a petal; of variable shape itself, but usually attenuate toward the base. |
|
blotch |
= macula, spot |
FEATURE |
|
An area that differs in color from the rest of a structure's surface. See also eyespot. |
