insertion |
|
Within the leaf sheath. |
ramal |
|
position |
|
Upon or otherwise directly associated with the stem branches. |
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. |
episepalous |
|
insertion |
|
Upon the sepals, or partially adnate thereto and apparently arising therefrom. |
barbed 1 |
|
apex |
|
Terminated by a small, relatively stiff, acutely reflexed, hook-like structure. |
V-form |
|
arrangement |
bundle scars |
Disposed in an open-ended triangular pattern, like the letter V. |
suffused |
|
coloration |
|
Having two or more hues, shades, and/or intensities intermingled, the contrasting components distinguishable only submacroscopically. |
knee 1 |
|
STRUCTURE |
|
An abrupt bend in an axial or other elongate structure. |
prismatic |
|
solid shape |
|
Uniformly polygonal in transverse section, basally and apically truncate, all faces essentially plane. |
eucamptodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, the secondary veins upwardly arcuate, gradually becoming indistinct interior to the margin, and serially interconnected by cross-branches without formation of marginal loops. |
abortive |
|
maturation |
spore, pollen, seed |
Never attaining functional maturity due to defective or arrested development. |
microphyll |
|
STRUCTURE |
|
A small, lateral, leaf-like enation that, evolutionarily, is not a true leaf, i.e., whose vasculature, if any, consists of only a single median strand not ontogenetically integral with the vasculature of the bearing stem and not associated with leaf gaps in the stele of the stem; in Bryophyta, Psilotophyta, Lycopodiophyta, Equisetophyta. |
farina pl. farinae, farinas |
|
SUBSTANCE |
|
A dry, meal- or flour-like covering. |
oblong 2 |
|
solid shape |
|
Compressed-ellipsoid, the sides approximately parallel from near one end to near the other. See also ellipsoid(al). |
coating |
|
CHARACTER |
|
Exudate that covers the surface proper. See also indumentum (vesture), pubescence. |
pachycaulous |
|
architecture |
plant |
Having thick, more or less succulent stems. |
alternate 1 |
|
arrangement |
|
Inserted singly along the axis, each at a different level and each diverging on a different radius than the ones next above and below. |
prop-rooted |
|
architecture |
plant |
Bearing and buttressed by prop roots. |
angled |
|
solid shape |
|
Having sides that meet at acute or obtuse angles. |
decussate |
|
arrangement |
|
Opposite with successive pairs radially oriented at right angles to one another, thus polystichous with four equidistant ranks. |
location |
|
CHARACTER |
|
Position with respect to aspects of environmental context. |
biennial 1 |
|
duration |
plant, stem |
Normally living two years; germinating or forming and growing vegetatively during one cycle of seasons, then reproducing sexually and dying during the following one. |
pulvinate 1 |
|
architecture |
inflorescence axis, petiole |
Having a pulvinus. |
rhizophore |
|
STRUCTURE |
|
A stem branch that bears no leaves and from which roots eventually arise; esp. in Selaginellaceae. |
heterocolpate |
|
architecture |
pollen grain |
Having long, narrow, regularly disposed lacunae (pseudocolpi). |
