|
setiform |
= bristle-shaped, setaceous |
solid shape |
|
Elongate, slender, terete, straight, terminating in a fine point, and apparently stiff; like a bristle. |
|
geniculate |
= kneed |
solid shape |
|
Elongate, abruptly bent, somewhat thicker at the angle, and appearing as though articulate like a leg at the knee. |
|
supple |
= flexible, pliable, pliant |
texture |
|
Able to bend over its length and/or breadth without structural disruption. |
|
knee root |
|
STRUCTURE |
|
A specialized secondary root of a wetland tree, a portion of which projects above mean water level and appears to bend as a leg does at the knee, its distalmost portion being anchored in the substrate beneath the water. The knee of the root is commonly regarded as a conduit for gas exchange between root interior and atmosphere, a function whose need is posited on the basis of the highly anaerobic and saturated conditions prevailing in wetland substrates. |
|
triple-… |
= thrice-…, tri-… |
prefix |
|
Indicating presence of three hierarchical orders of the type of entity or pattern denoted by the term's stem; as in triple-palmate. See also three-…. |
|
axehead-shaped |
= dolabrate |
solid shape |
|
Like an axe head oriented cutting edge downward. |
|
meniscoid |
|
solid shape |
|
Relatively thin with opposite, round, broad faces, one convex and one concave (as viewed externally), the circumferential edge angular or rounded; like a meniscus. See also discoid (disciform), lenticular (biconvex, lens-shaped), patelliform (kneecap-shaped). |
|
callose |
= callous |
texture |
|
Hard-leathery; callose tissue usually is also thicker than comparable adjacent tissue. |
|
obtuse 2 |
= blunt |
base |
|
Bluntly angular; having an angular proximal portion whose generalized sides intersect at an angle of 90° or more. |
|
close |
= approximate |
arrangement |
|
Disposed relatively near to one another. |
|
pericarp |
|
STRUCTURE |
|
The portion of a fruit wall that is derived from the ovary wall; consisting of three more or less distinct tissue layers (exocarp or epicarp, mesocarp, and endocarp) that may or may not differ greatly in structure and/or function; the wall of a fruit, excluding any tissues of extra-ovarian (accessory) origin. |
|
cross-shaped 2 |
= cruciate |
solid shape |
|
Having two elongate, basically straight portions intersecting at a point interior to the ends of each. |
|
divergent |
|
arrangement |
|
Directed at individually different angles from a common point or relatively limited zone of origin, thus farther apart distally than proximally. |
|
extent |
|
CHARACTER |
|
Reach of the septum or septa within the ovary or fruit, relative to the ovary wall or pericarp and its center. |
|
selliform var. sellaeform |
= saddle-shaped |
solid shape |
|
Relatively thin, broad and long, strongly compound-curved, concavely from end to end and convexly from side to side; like the generalized shape of a saddle. |
|
splendent |
= glittering |
reflectance |
|
Interruptedly glossy (laevigate, lustrous, polished, shining, shiny) and thus sparkling when viewed from changing angles. |
|
helmet-shaped |
= galeate, galeiform |
solid shape |
|
Convex overall with a more or less smoothly curved apex, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a helmet. See also hood-shaped (cucullate, cuculliform), which overlaps conceptually. |
|
subspheric(al) |
= subglobose, suborbicular, subrotund, subspheroid(al) |
solid shape |
|
Broadly ellipsoid with a length:width ratio closely approaching 1:1; almost spheric(al), slightly longer than broad. |
|
intricate |
|
arrangement |
|
Entangled; irregularly intertwined and not readily disentangled. |
|
…-toothed 1 |
= …dentate |
apex |
|
Generally truncate but with the number of antrorse, attenuate, distal lobes indicated by the prefix; as in three-toothed. |
|
lineolate 2 |
|
relief |
|
Finely lineate, the depressions or protrusions short and often irregularly oriented. |
|
vein |
= nerve; > costa, midnerve, midrib, midvein, rib |
STRUCTURE |
|
A strand belonging to any except the ultimate (least in diameter) order of vasculature in a leaf or other foliaceous structure. See also lateral vein, primary vein, secondary vein, tertiary vein, veinlet. |
|
adventitious |
|
derivation |
|
Arising more or less unpredictably from an organ, tissue, or site that is an unusual, abnormal, or atypical origin for structures of its type. |
|
arrowhead-shaped 2 |
= sagittate |
plane shape |
|
Generally triangular, tapering gradually from the base to an acute apex, the base with a relatively large, acute, retrorse lobe to either side; like the outline of the broad lateral face of an arrowhead. |
|
mamma pl. mammae |
|
STRUCTURE |
|
A rounded-conoidal protrusion, resembling the breast of a mammal. |
