straight |
|
course |
|
Lacking significant curves or bends. |
divergent |
|
arrangement |
|
Directed at individually different angles from a common point or relatively limited zone of origin, thus farther apart distally than proximally. |
pistillodium pl. pistillodia |
= pistillode |
STRUCTURE |
|
Any sterile structure deemed to represent a modified pistil, homology being inferred on the basis of structural similarity, ontogeny, and/or position; sometimes nectariferous, sometimes connate with others or adnate to other floral structures. |
pulvinate 2 |
= cushion-shaped, mound-shaped, pulviniform |
solid shape |
|
Essentially round in transverse section, much broader than long or high, with a convex distal face that intersects either a more or less plane proximal face or, when the structure is sessile, its bearing surface. |
flush |
|
prominence |
|
Even with the surrounding surface, neither higher nor lower than its general level. |
cross-vein |
|
STRUCTURE |
|
A relatively short, secondary or higher-order vein that runs directly between two veins of the next lower order, intersecting them more or less perpendicularly. |
macrospore (not recommended) |
= megaspore |
STRUCTURE |
|
A female spore; a spore of the larger of two types produced by the sporophytes of a heterosporous taxon; produced in a megasporangium; giving rise upon germination to a megagametophyte. |
annular |
= ring-shaped |
solid shape |
|
More or less evenly tubular in a closed circle; like a ring or doughnut. |
hexa… |
= six-… |
prefix |
|
Indicating presence of or constitution by six entities of the type denoted by the term's stem; as in hexandrous, hexacarpellate, hexacolporate. |
tessellate 1 |
= checkered |
coloration |
|
Having a pattern of more or less regularly disposed square zones of contrasting hues and/or intensities. |
twice-… |
= bi…, double-… |
prefix |
|
Indicating presence of two hierarchical orders of the type of entity or pattern denoted by the term's stem; as in twice-crenate, twice-palmate. See also two-… (bi…, di…). |
vexillum pl. vexilla |
= banner, standard |
STRUCTURE |
|
The relatively large, erect adaxial (upper) petal in a papilionaceous corolla. |
mucilage |
|
substance |
|
A slimy exudate. |
reticulodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, branching repeatedly, becoming less distinct, and yielding a dense higher-order reticulum near the margin. |
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. |
retrorse |
|
orientation |
|
Directed generally backward, toward the proximal end of the context of reference, parallel or at an acute angle to the bearing structure. |
prominent |
< raised |
prominence |
|
Protruding above the general level of the surrounding surface. See also prominulous. |
patelliform |
= kneecap-shaped |
solid shape |
|
Thickly meniscoid, like a human kneecap. |
symmetric(al) 1 |
|
solid shape |
|
Divisible into essentially equal halves along one or more lines or planes. |
lip cell |
|
STRUCTURE |
|
Either of a pair of adjacent, narrow, transversely oriented, thick-walled cells bordering the pore (stomium) of a sporangium. |
epipetalous |
|
insertion |
|
Upon the petals, or partially adnate thereto and apparently arising therefrom. |
calyx pl. calyces |
|
STRUCTURE |
|
Collectively, the sepals of a flower, whether distinct or connate; the outer or proximal envelope of a differentiated perianth, whether the other envelope (corolla) is also actually present or is deemed to be secondarily absent due to evolutionary reduction. |
headless 2 |
= acephalous |
solid shape |
|
Not terminating in a head-like portion, esp. when one might be expected. |
trowel-shaped |
= trullate, trulliform |
plane shape |
|
Broadest below the middle, more or less straightly attenuate to either end, the sides angled at the level of greatest width; like the blade of a mason's trowel. See also obtrullate, obtrulliform. |
one-… |
= mono…, single-…, uni… |
prefix |
|
Indicating presence of or constitution by one entity of the type denoted by the term's stem; as in one-carpelled, one-loculed, one-seeded. See also entries for particular terms beginning with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. |
