Heterogeneously porous, with macroscopically distinct concentric seasonal growth increments (rings), each with numerous large vessels toward the inside and fewer and smaller ones toward the outside. |
|
blunt 2 |
= obtuse |
base |
|
Bluntly angular; having an angular proximal portion whose generalized sides intersect at an angle of 90° or more. |
|
column 1 |

STRUCTURE |
|
A central floral structure consisting of the partly to wholly fused (connate and adnate) androecium and gynoecium; esp. in Orchidaceae. |
|
pseudoterminal |

position |
|
Only apparently terminal; originally subapical but displaced toward the apex by differential growth during development. |
|
lentiginous |
= dusty, lentiginose |
coating |
|
Covered with a more or less even deposit of minute, dry, macroscopically indistinguishable particles. See also pulverulent (granuliferous, powdery), which is not clearly distinct in its application. |
|
trapeziform |
|
plane shape |
|
Four-sided and either asymmetrical or bilaterally symmetrical like a triangle truncated distally perpendicular to its central axis. |
|
mealy 1 |
= farinaceous; < crumbling, fatiscent |
texture |
|
Of or bearing minute, relatively stout trichomes that are collectively meal- or flour-like and easily detached. |
|
flabelliform |
= fan-shaped, flabellate |
solid shape |
|
Strongly compressed, broadest near the apex and attenuate to a narrow base, plaited longitudinally, the alternating folds radiating from the base, the whole basically triangular in broad aspect; like a partially expanded folding fan. |
|
scutelliform |
= platter-shaped, scutellate |
solid shape |
|
Relatively thin with opposite broad oval faces, shallowly concave-convex; like a serving platter. See also scutate (buckler-shaped, scutiform), which is not clearly distinct in its application. |
|
inframedial |
|
position |
|
Slightly below the middle of the structure in point. |
|
superficial |
= surficial |
insertion |
|
Directly upon the surface of the structure in point. |
|
crenule |
= scalloplet |
FEATURE |
|
A diminutive crena (scallop). See also dens (tooth), sawtooth, sawtoothlet, toothlet. |
|
enlarged |
|
size |
|
Unusually or unexpectedly large. |
|
antheridium pl. antheridia |
|
STRUCTURE |
|
A male gametangium; a multicellular fertile organ of a mature gametophyte within which male gametes (antherozoids, spermatozoids) are produced and from which they are discharged, in some taxa forcibly, through a pore. Technically present but highly reduced and of no descriptive significance in Magnoliophyta and part of Pinophyta. |
|
resinous 1 |
|
coating |
|
Of liquid or hardened resin. |
|
size |
|
CHARACTER |
|
Nature as to absolute or comparative extent in any one dimension or in area or volume. |
|
haustorium pl. haustoria |
|
STRUCTURE |
|
An absorbing and anchoring organ, often root-like, excrescent from a vegetative part of a parasitic or hemiparasitic plant, by which the plant communicates intimately with and derives sustenance and support from its host plant, into whose tissues the haustorium intrudes. |
|
piliferous |
|
apex |
|
Having a distinct, fine, weak, hair-like portion or protrusion. |
|
lanuginose |
< cottony |
pubescence |
|
Bearing relatively long and fine, intertwined, somewhat matted, capillate trichomes. |
|
throat 1 |
|
STRUCTURE |
|
The far distal portion of a perianth, calyx, or corolla tube, or of a leaf sheath, surrounding the orifice of the tube or sheath, sometimes constricted relative to the diameter of the main body of the tube or sheath; except in disc florets of Asteraceae (Compositae). |
|
female cone |
= macrostrobilus (not recommended), megastrobilus |
STRUCTURE |
|
A cone (strobilus) whose fertile organs are all megasporophylls. |
|
scabridous |
= rough, scabrate, scabrid, scabrous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
|
bearded |
= barbate |
pubescence |
|
Having one or more limited sectors bearing relatively long, erect, flexible, capillary trichomes. |
|
woolly |
> lanate |
pubescence |
|
Of or bearing relatively long, moderately stout, intertwined, somewhat matted, capillate trichomes. |
|
oval |
= elliptic(al) |
plane shape |
|
Elongate, widest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
