STRUCTURE / SUBSTANCE |
|
See vesture. |
|
barbellulate |
|
architecture |
|
Bearing one or more barbellules (barbellulae). |
|
stipel |
|
STRUCTURE |
|
A stipular analogue subtending a leaflet. |
|
face |
|
FEATURE |
|
A relatively large, flat or shallowly curved portion of the external surface of a three-dimensional structure, bounded by more or less distinct topological discontinuities. |
|
umbellate |
|
architecture |
inflorescence |
Comprising one or more umbels. |
|
scaly 2 |
|
architecture |
bud, bulb |
Invested by scale-like (squamiform) structures. |
|
biennial 2 |
|
nominative |
plant |
Of biennial duration. |
|
subtending |
|
insertion |
|
Arising from the axis just below and very near to the base of some other specified lateral structure. This term is meaningless if the structure that is subtended is not indicated. |
|
lenticel |
|
STRUCTURE |
|
A specialized, anatomically distinct structure within the periderm of a stem, consisting of comparatively spongy, sometimes suberized tissue distinct from others of the periderm; extending radially through the periderm and visible as a circular to elongate discontinuity in the color, texture, and/or relief of the outer surface of the stem; serving as a conduit for gas exchange between the stem interior and the atmosphere. |
|
deciduous 2 |
|
habit |
plant |
Perennial and having all leaves separating and falling away during a particular portion of the yearly cycle, especially the autumn or the dry season, between growing seasons. Semantically, this term is properly applied only to the entity that falls, not to the structure that it separates and falls from; in traditional usage, though, the term has been applied to trees and other perennial plants that shed all their leaves at some time during the yearly cycle. |
|
style |
|
STRUCTURE |
|
A narrow, usually elongate, ontogenetically distal portion of a simple or compound pistil, overtopping the ovary and bearing one or more stigmas; arising from the summit of the ovary, but sometimes apparently from its base at maturity to ontogenetic displacement from its primordial distal position. In a compound pistil the various simple (carpellary) components of the style(s) may not be connate over their entire lengths; the pistil is then regarded as having a branched style or styles. |
|
epinastic |
|
development |
laminar structure |
Having the adaxial surface differentiating and growing faster than the abaxial surface, thus, until maturity, development of the former more advanced than that of the latter at any given time and the structure as a whole revolute or recurved. |
|
laminate |
|
architecture |
foliaceous structure |
Having an expanded, more or less planate, distal portion (lamina or blade). |
|
anchoring |
|
habit |
trichome |
Serving as a means of attachment to some external support. |
|
aristate 2 |
|
apex |
pappus scale |
Terminating in one or more awn- or bristle-like appendages. |
|
suprabasal |
|
position |
|
Just above the base of the structure in point. |
|
piliferous |
|
apex |
|
Having a distinct, fine, weak, hair-like portion or protrusion. |
|
apotropous |
|
orientation |
ovule |
Anatropous but the whole recurved such that the raphe (adnate portion of the funiculus) faces the ovary wall (placenta) and the ovule is parallel to it, the micropyle facing the free basal portion of the funiculus. |
|
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. |
|
fruit |
|
STRUCTURE |
|
Any unitary seed-bearing structure of a flowering plant, consisting of the matured or ripened pistil(s) of one or more flowers along with any other floral or vegetative tissue(s) persisting adnate to them; characteristic of and unique to Magnoliophyta (Angiospermae). |
|
rhytidomal |
|
position |
|
Within, upon, or otherwise directly associated with the bark. |
|
aciculate |
|
coloration |
|
Having fine, irregularly oriented, straight streaks of contrasting hue and/or intensity. |
|
plane shape |
|
CHARACTER |
|
Overall two-dimensional form or aspect(s) thereof. Overlaps conceptually with architecture, arrangement, habit, insertion, orientation, and position. |
|
microgametophyte |
|
PLANT |
|
A gametophyte whose fertile organs (gametangia) are all antheridia. |
|
cell 1 |
|
STRUCTURE |
|
Any of the basic structural/functional units that collectively or individually make up the various tissues of a plant; comprising, at least while physiologically active, a nucleus with included genetic material (chromosomes), a surrounding cytoplasm with included organelles (e.g., ribosomes, mitochondria, plastids), an enclosing membrane, and an exterior cellulosic wall. |
