unifacial |
|
architecture |
|
Having two opposite broad surfaces that are essentially similar in appearance. |
carpophore 3 |
= columella; < stalk |
STRUCTURE |
|
The stalk supporting a mericarp after dehiscence of a schizocarpic fruit, the central axis of the fruit having split longitudinally to yield two or four such stalks; composed of receptacular and (primarily) gynoecial tissues; esp. in Apiaceae (Umbelliferae). |
round |
= orbiculate, orbicular misapplied |
plane shape |
|
Circular. |
opposite 2 |
|
arrangement |
|
Having the members of each whorl inserted directly above and/or below those of the next adjacent whorl(s). See also antipetalous, antisepalous. |
interpetiolar |
< nodal |
position |
|
Upon the stem between the bases of opposite leaves. |
joint |
= articulation |
STRUCTURE |
|
A distinct, relatively narrow zone of demarcation between adjacent main portions of an elongate structure, often thicker than the rest of the structure and sometimes a site of eventual abscission. |
branch |
|
STRUCTURE |
|
Any higher-order division of or outgrowth from an axis, vein or veinlet when such division or outgrowth is equivalent in nature to the structure of origin. |
small-dotted |
= puncticulate |
coloration |
|
Finely dotted (punctate). |
filament |
|
STRUCTURE |
|
The stalk, when present, of a stamen, clearly differentiated from and bearing at its summit an anther. |
bell-shaped |
= campanulate |
solid shape |
|
Circular in cross-section, inflated proximally, thence broadening gradually to a flared distal portion. |
conic(al) |
= cone-shaped |
apex |
|
Transversely round, essentially triangular in median longitudinal section, and broadest proximally. See also obconic(al). |
turion |
< sucker |
STRUCTURE |
|
A scaly sucker. |
spotted |
= blotched, maculate |
coloration |
|
Having one or more areas that differ in color from the rest of the surface. See also eyespotted. |
rhytidomal |
|
position |
|
Within, upon, or otherwise directly associated with the bark. |
style |
|
STRUCTURE |
|
A narrow, usually elongate, ontogenetically distal portion of a simple or compound pistil, overtopping the ovary and bearing one or more stigmas; arising from the summit of the ovary, but sometimes apparently from its base at maturity to ontogenetic displacement from its primordial distal position. In a compound pistil the various simple (carpellary) components of the style(s) may not be connate over their entire lengths; the pistil is then regarded as having a branched style or styles. |
induplicate |
|
aestivation |
|
Basically valvate but with each member involute, the lateral abaxial surfaces of adjacent members contiguous. |
indurate(d) |
= hard |
texture |
|
Yielding only under strong pressure; not deformable without internal structural disruption. See also callose (callous), corticate (hard-coated), sclerocaulous (hard-stemmed). |
scutate |
= buckler-shaped, 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 scutellate (platter-shaped, scutelliform), which is not clearly distinct in its application. |
…dentate 2 |
= …-toothed |
margin |
|
Having the number of orders of dentes (teeth) indicated by the prefix, one upon another; as in twice-dentate. See also …crenate (…-scalloped), …serrate (…-sawtoothed). |
puberulent |
|
pubescence |
|
Finely pubescent in the restricted sense of that term. |
bifurcate |
< forked, furcate |
solid shape |
|
Having two terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
shoot 1 |
|
STRUCTURE |
|
Collectively, all those portions of a plant body that are anatomically distinct from the root, the component axes differentiated into nodes and internodes, and branching exogenously from the former. |
fan-shaped |
= flabellate, flabelliform |
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. |
annulus 2 pl. annuli |
|
STRUCTURE |
|
A row of protruding specialized sporangial wall cells that extends upward from the base of the sporangium and over its apex, thus forming an incomplete circumferential ring; esp. in Polypodiophyta. The inner and radial walls of the annular cells are markedly thickened and the structure functions as a spore-releasing and -disseminating mechanism as a result of differential stresses developed within the mature sporangial wall upon desiccation. |
barb 1 |
|
STRUCTURE |
|
Any relatively short, stiff, sharp, acutely inserted or bent, antrorse or retrorse, terminal or lateral appendage. |
