stem |
> cane, culm |
STRUCTURE |
|
The entire axial system of a shoot, or a component, primary or higher-order (branch) axis of the shoot; differentiated anatomically and morphologically into nodes and internodes, from the former of which it branches exogenously and bears leaves, bracts, and/or inflorescences; usually growing above ground level, but sometimes structurally and functionally specialized and growing underground (e.g., rhizome, tuber) or upon the surface of the ground (e.g., stolon). Although sometimes phenotypically distinctive and often treated separately for descriptive purposes, the axial system of an inflorescence, excluding pedicels or parts of them in some cases, is properly stem in the above general sense. |
auricle |
= ear |
STRUCTURE |
|
A small, rounded, lateral lobe at the base of a laminar structure, lying in more or less the same plane as the remainder of the lamina. |
hooked |
= hamate, uncinate |
apex |
|
Having a recurved terminal portion that resembles a hook. |
weak |
|
texture |
|
Very pliable and unresilient. |
lens-shaped 2 |
= biconvex, lenticular |
solid shape |
|
Relatively thin with two round, convex, opposite broad faces intersecting acutely at the circumferential edge; like a double-convex lens. See also disciform (discoid), meniscoid. |
ring-shaped |
= annular |
solid shape |
|
More or less evenly tubular in a closed circle; like a ring or doughnut. |
sporangiophore |
< stalk |
STRUCTURE |
|
A stalk that bears one or more sporangia. |
terminal |
|
position |
|
Apical and with the same developmental axis as the whole, of which it is the distalmost portion or appendage. |
indument |
|
STRUCTURE / SUBSTANCE |
|
See indumentum. |
seriate |
= cyclic, verticillate, whorled |
arrangement |
|
Disposed along the axis in groups of three or more, the members of each group (cycle, series, verticil, whorl) inserted around the axis at the same level. |
non-porous |
|
porosity |
|
Lacking vessels, the tracheary elements limited to tracheids and, sometimes, fiber-tracheids. |
female |
= feminine |
reproduction |
|
Of the sex that produces megaspores and ova. |
twelve-… |
= dodeca… |
prefix |
|
Indicating presence of or constitution by twelve entities of the type denoted by the term's stem; as in twelve-loculed, twelve-stamened, twelve-styled. |
apiculate |
|
apex |
|
Terminating abruptly in a short, slender, angular tip that is not notably harder or stiffer than the main body of the structure. See also mucronate, mucronulate. |
brochidodromous |
|
venation |
|
Having a single median primary vein that branches to either side along its length, the secondary veins incurving strongly near but short of the margin, interconnecting serially, and forming a succession of marginal loops. |
verticillate |
= cyclic, seriate, whorled |
arrangement |
|
Disposed along the axis in groups of three or more, the members of each group (cycle, series, verticil, whorl) inserted regularly around the axis at the same level. |
lancehead-shaped 1 |
= lanceolate |
plane shape |
|
Elongate, moderately narrow, broadest just above the base and gradually attenuate toward the apex, the sides more or less straight; like the outline of the broad lateral face of a lance head. See also oblanceolate. |
resinous 2 |
|
texture |
|
Having the consistency of resin. |
sperm |
> antherozoid, spermatozoid |
STRUCTURE |
|
A male gamete. |
scale-like |
= squamiform |
solid shape |
|
Isodiametric to elongate in broad outline, relatively very thin, and planate to moderately concave-convex. |
half-terete |
= semiterete |
solid shape |
|
Terete but flattened on one side. |
aciculate |
|
coloration |
|
Having fine, irregularly oriented, straight streaks of contrasting hue and/or intensity. |
cruciate 2 |
= cross-shaped |
solid shape |
|
Having two elongate, basically straight portions intersecting at a point interior to the ends of each. |
