capsular |
|
architecture |
fruit |
Having the structure and texture of a capsule. |
vascular bundle |
|
STRUCTURE |
|
A discrete strand of conducting tissues (xylem, phloem) and associated cells (e.g., cambium) within a stem or other axial structure. |
antipetalous |
|
insertion |
equivalent floral structures |
Each inserted directly above or below a petal. In place of this term, the phrase "opposite the petals" is often used, but that contradicts the sense of opposite as otherwise employed (arrangement of lateral structures along an axis) and should be avoided. |
tetradynamous |
|
architecture |
flower, androecium |
Diadelphous with four stamens in one set and two in the other. See also didynamous. |
taprooted |
|
architecture |
plant |
Having a taproot. See also diffuse-rooted, fibrous-rooted. |
arcuate 1 |
|
course |
|
Curving more or less regularly in one direction. |
acetabuliform |
|
solid shape |
|
Transversely circular, broader than long, widest near or at the middle, relatively thin-walled, the hollow interior open distally; like a shallow bowl with strongly incurved sides. |
adventitious root |
|
STRUCTURE |
|
A root that arises laterally from some part of a shoot, often from the lower portion of a main stem. |
rhytidomal |
|
insertion |
|
Within, upon, or otherwise directly associated with the bark. |
mesochilium |
|
STRUCTURE |
|
The central portion of a labellum (lip) that has distinct proximal, distal, and central parts; in Orchidaceae. See also epichilium, hypochilium. |
annual 1 |
|
duration |
plant, stem |
Normally living one year or less; growing, reproducing, and dying within one cycle of seasons. |
stipule scar |
|
FEATURE |
|
A scar on a stem or petiole due to abscission of a stipule; having an outline like that of a transverse section through the base of the stipule inserted there; variously disposed, usually in pairs, adjacent to a point of leaf insertion, sometimes confluent with the leaf scar, sometimes confluent with stipule scars associated with an opposite leaf, the two sets of scars then more or less encircling the axis. |
intruded |
|
placentation |
|
Upon partial septa excrescent from the wall of a compound, unilocular ovary. |
peripterous |
|
solid shape |
|
Alate with a single transversely encircling wing. |
polyadal |
|
arrangement |
pollen |
Shed in groups of more than four, each group comprising grains from two or more original tetrads, the latter intact or not. |
floating 1 |
|
habit |
plant |
Buoyant and growing entirely at or near the surface of water, not rooted in any substrate. |
suprafoliar |
|
insertion |
|
Upon the stems, each directly above (distal to) and very near a point of leaf insertion. |
prolate |
|
plane shape |
|
Symmetrically elongate parallel to the developmental or polar axis. |
basiscopic |
|
orientation |
subordinate structure |
Directed, facing, or pointing ("looking") toward the base of the bearing structure. |
brachiate |
|
architecture |
axis |
Having alternate, divaricate branches. |
gelatinous |
|
texture |
|
Jelly-like; soft, moist, continuously cohesive, texturally homogeneous, somewhat resilient, and easily cut. |
commissure |
|
FEATURE |
|
Precisely, the joint or common boundary between the facing surfaces of two coherent or mutually appressed structures such as mericarps or stigmas, but traditionally (though imprecisely) applied to such a facing surface itself. |
palmatipinnate |
|
architecture |
foliaceous structure |
Compound with two orders of leaflets, the first order palmate, the second pinnate. |
disc floret |
|
STRUCTURE |
|
A floret that has an actinomorphic corolla, is bisexual, functionally staminate, or functionally pistillate, and is borne in a radiate, discoid, disciform, or radiant capitulum (head) interior (distal) to any peripheral series of differing florets that may be present; in Asteraceae (Compositae). |
winter annual |
|
nominative |
plant |
Annual, germinating in autumn, overwintering in a vegetative state (usually as a rosette aboveground), reproducing sexually from early spring through summer, and dying promptly thereafter. See also summer annual. |
