rhytidomal |
|
insertion |
|
Within, upon, or otherwise directly associated with the bark. |
|
exudation |
|
CHARACTER |
|
Discharged substance, as to type. |
|
semiterete |
= half-terete |
solid shape |
|
Terete but flattened on one side. |
|
spore case |
= sporangium |
STRUCTURE |
|
A spore-producing organ; basically capsular, often supported by a slender stalk (sporangiophore), often lidded (operculate). In Bryophyta and Polypodiophyta, a distinct portion of the sporangial wall effects regular dehiscence at maturity. Spore cases or their equivalents are also present, but of little or no descriptive significance, in seed plants. |
|
subterranean |
= hypogeal, hypogeous |
location |
|
Within the ground, beneath its surface. |
|
tortuous |
|
course |
|
Strongly irregular with sharp bends and/or curves. |
|
velvety |
= velutinous |
pubescence |
|
Of or bearing dense, moderately firm, more or less erect, capillate trichomes, like velvet pile to the touch. |
|
aestivation |
|
CHARACTER |
|
Disposition of perianth (undifferentiated), calyx, or corolla members in the bud. |
|
ascidiform |
= pitcher-shaped |
solid shape |
|
Having a more or less tubular, radially or bilaterally symmetrical body closed at the base and broadening toward a more or less open apex sometimes lidded or overarched by a prolongation of one side; like a pitcher. |
|
buckler-shaped |
= scutate, scutiform |
solid shape |
|
Relatively thin with opposite broad oblong faces, planate to shallowly concave-convex, sometimes thickened about the periphery such that each face has a marginal rim; like an oblong shield. See also platter-shaped (scutellate, scutelliform), which is not clearly distinct in its application. |
|
obcordiform |
|
solid shape |
|
Inversely cordiform (heart-shaped). |
|
circinate 1 |
|
solid shape |
|
Terete and rolled downward from the apex in a tight coil. |
|
pectinate |
= comb-shaped |
plane shape |
|
Finely divided, the divisions slender, oriented more or less perpendicular to the central axis, and resembling the teeth of a comb. |
|
porosity |
|
CHARACTER |
|
Presence and disposition of vessels (pores) in wood (xylem). |
|
relief |
= sculpture |
CHARACTER |
|
General topographic aspect of a surface. Overlaps conceptually with solid shape. |
|
equatorial ridge |
|
FEATURE |
|
A circumferential ring about a megaspore in the plane of its equator, raised above the remainder of the wall surface; in some heterosporous taxa of Polypodiophyta. |
|
scrotiform |
= scrotum-shaped |
solid shape |
|
Saccate (bag-, pouch- or sack-shaped) and somewhat swollen bilaterally in the distal portion; like a scrotum. |
|
spheroid(al) |
= globose, globular, orbicular, rotund, spheric(al) |
solid shape |
|
Uniformly convex, circular in any median section and in outline when viewed from any angle; like a sphere or globe. |
|
strophiole |
= caruncle |
STRUCTURE |
|
An outgrowth from the seed coat (testa) around or near the hilum and micropyle, or from the raphe. |
|
infrabracteal |
|
position |
|
Upon the axis directly below a bract insertion. |
|
lepidote |
= squamose; < scaly |
pubescence |
|
Bearing lepides (squamae). See also squamellose. |
|
unilateral 3 |
= one-sided |
insertion |
|
Upon or arising from one side only of the bearing structure. |
|
acicular 2 |
= acerose, needle-shaped |
solid shape |
|
Rounded in cross-section and very slenderly elongate, broadest near the middle, and gradually attenuate to an acute apex and a slightly blunter base; like a needle. |
|
approximate |
= close |
arrangement |
|
Disposed relatively near to one another. |
|
lodicule |
= squamella |
STRUCTURE |
|
One of two or three small, scale-like structures inserted at the base of the androecium, distal to the palea, in most grass (Poaceae) flowers; often regarded as a vestigial branch or perianth member. |
