dot-like |
= punctiform |
plane shape |
|
Very small and generally circular in outline. |
tetrad scar |
|
FEATURE |
|
A surficial ridge or angle resulting from coherence with other spores produced from the same mother cell. |
spadix pl. spadices |
|
STRUCTURE |
|
A thick, fleshy, primary inflorescence axis bearing sessile flowers more or less sunken into its surface, the whole subtended and sometimes partially enclosed by a specialized bract, the spathe; esp. in Araceae. |
bulb |
|
STRUCTURE |
|
A thickened underground perennating structure consisting of a stem with numerous closely proximate nodes bearing many tightly imbricate, thickened, often fleshy, foliaceous organs containing large amounts of stored food, usually in the form of starch; the whole usually enveloped and protected by imbricated scarious or fibrous foliaceous organs. |
vascular bundle |
|
STRUCTURE |
|
A discrete strand of conducting tissues (xylem, phloem) and associated cells (e.g., cambium) within a stem or other axial structure. |
bent |
= flexed |
solid shape |
|
Having an abrupt bend at some point along its length. See also declinate (inclinate), geniculate (kneed), inflexed, reflexed. |
scale-like |
= squamiform |
solid shape |
|
Isodiametric to elongate in broad outline, relatively very thin, and planate to moderately concave-convex. |
aerial |
|
location |
|
Above ground or water level. |
apical |
< distal |
insertion |
|
At or very near the developmental end or tip (apex) of a structure. |
leaf 1 pl. leaves |
= frond, macrophyll (not recommended), megaphyll; > frond, needle |
STRUCTURE |
|
A principal, vegetative shoot organ borne laterally from a stem node; its vascular tissues, if any, continuous with those of the stem; undergoing no significant secondary growth; usually more or less bilaterally symmetrical; comprising a distal, usually laminar blade and/or a proximal stalk (petiole) or sheath; usually a primary site of photosynthesis. |
macrostrobilus pl. macrostrobili (not recommended) |
= female cone, megastrobilus |
STRUCTURE |
|
A strobilus (cone) whose fertile organs are all megasporophylls. |
rudimentary |
= obsolete (not recommended); > vestigial |
manifestation |
|
Not developing fully and not functional compared with corresponding structures in other taxa. |
epipetalous |
|
insertion |
|
Upon the petals, or partially adnate thereto and apparently arising therefrom. |
falcate 1 |
= sickle-shaped |
plane shape |
|
Elongate and laterally arcuate with the lateral edges more or less concentric, the degree of curvature decreasing distally or not; like the outline of the face of a sickle blade. |
epipetalous |
|
position |
|
Upon the petals, or partially adnate thereto and apparently arising therefrom. |
falcate 2 |
= sickle-shaped |
solid shape |
|
Elongate, strongly compressed, and arcuate in the plane of compression, the two faces more or less plane and parallel, the degree of curvature decreasing distally or not; like a sickle blade. |
half-obterete |
= semiobterete |
solid shape |
|
Inversely half-terete; obterete but flattened on one side. |
irregular 2 |
|
course |
|
Deviating asymmetrically from a straight line. |
four-… |
= quadr(i)…, tetra… |
prefix |
|
Indicating presence of or constitution by four entities of the type denoted by the term's stem; as in four-angled, four-petaled, four-ranked. |
discal |
|
position |
|
Upon or otherwise directly associated with the floral disc. |
barbate |
= bearded |
pubescence |
|
Having one or more limited sectors bearing fairly long, erect, flexible, capillary trichomes. |
S-shaped 2 |
= sigmoid |
solid shape |
|
Elongate with more or less constant width or diameter and curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |
