declined |
= inclined |
orientation |
|
Directed downward or backward. |
supramedial |
|
position |
|
Just above the middle of the structure in point. |
lanulose |
|
pubescence |
|
Finely lanate. |
granulose |
= granular, granulate |
texture |
|
Composed of grain-like particles; loose, dry, and coarsely particulate. |
spore |
|
STRUCTURE |
|
A simple, usually unicellular, sometimes oligocellular propagule derived by meiotic division of a diploid (2n chromosomes) sporocyte within a sporangium, thus of haploid (n chromosomes) genetic constitution. A spore constitutes the first ontogenetic stage of a gametophytic generation and gives rise to a usually multicellular gametophyte upon germination. Though technically present in seed-bearing plants, by itself it is descriptively significant only in those taxa that do not produce seeds. |
ascidium pl. ascidia |
= pitcher, pitcher-blade |
STRUCTURE |
|
An ascidiform (pitcher-shaped) leaf blade, sometimes operculate (lidded), usually carnivorous; esp. in Nepenthaceae, Sarraceniaceae. |
unctuous 1 |
= greasy, oily, oleaginous |
coating |
|
Of a grease- or oil-like film. |
micropyle |
|
FEATURE |
|
The small pore in the integuments of an ovule at its apex, through which the pollen tube grows; or the corresponding aperture or scar in the coat of the seed that develops subsequently. |
pollen |
|
STRUCTURE |
|
Collectively, the spores or grains produced within the thecae of anthers, each containing a very small microgametophyte (or its evolutionary homologue); serving as disseminules from which microgametes are released after transport to a receptive micropylar pollen droplet (in Pinophyta) or stigma (in Magnoliophyta) by a variety of vectors, notably wind, water, insects, bats, and birds. |
trabeculate |
< septate |
architecture |
|
Having one or more trabeculae. |
rhytidomal |
|
position |
|
Within, upon, or otherwise directly associated with the bark. |
villose |
= shaggy, villous |
pubescence |
|
Bearing sparse, long, slender, soft, capillate trichomes that are not intertwined. See also villosulous. |
scale 1 |
< bract |
STRUCTURE |
|
A basically dry, more or less appressed, diminutive bract. The choice of term as between the more general bract and the more restricted scale is sometimes problematic and, when so, often is dictated by custom according to the structure and taxon involved. |
cucullus pl. cuculli |
= hood |
STRUCTURE |
|
A cucullate (cuculliform) structure or component, esp. in an inflorescence or flower. |
strigillose |
= strigulose |
pubescence |
|
Finely strigose. |
subulate 2 |
= awl-shaped |
solid shape |
|
Slender, essentially terete, and straight, gradually attenuate from a relatively narrow base to a very narrow, blunt to angular apex. |
knot-shaped |
= gongylodate, gongyloid, knob-shaped, nodiform |
solid shape |
|
Approximately globose, the surface convoluted or not, like a knob or knot; usually applied only to structures or components that are relatively small. |
dorsal (not recommended) |
= abaxial |
position |
|
On or pertaining to the side or portion of a lateral structure that faces (or would face) away from the bearing axis when (or if) the axis of the lateral structure is (or were) oriented in the same general direction as the bearing axis. |
glabrate |
= near-bald |
pubescence |
|
Nearly glabrous, with only a very sparse covering of trichomes. |
tuft |
> coma |
STRUCTURE |
|
A distinct, compact, relatively dense, homogeneous aggregation of plants or constituent structures such as stems, branches, leaves, bracts or trichomes. |
fixation |
|
CHARACTER |
|
Mode of attachment to a supporting structure. |
theca pl. thecae |
= pollen sac |
STRUCTURE |
|
Any of the one, two or four ontogenetically distinct, pollen-producing sectors (microsporangia) of an anther. In some taxa the walls between pairs of adjacent thecae break down as an anther approaches maturity, the mature anther thus ultimately containing half as many locules as thecae. |
corrugate 2 |
= rugose, wrinkled |
relief |
|
Having irregular, narrow ridges or creases, the intervening areas flat or only slightly concave or convex, appearing overall as though crumpled and then spread out. See also rugulose. |
remote |
= distant |
arrangement |
|
Disposed relatively far from one another along the axis. |
alveolate |
= honeycombed |
relief |
|
Having generally uniform, regularly and closely disposed, transversely polygonal depressions overall, the pattern resembling the external aspect of a honeycomb. |
