fibrous root |
< diffuse root |
STRUCTURE |
|
A diffuse root that includes a significant component of woody or sclerotic strands and is consequently tough and often wiry. |
scallop |
= crena |
FEATURE |
|
A rounded, marginal convexity or concavity in a series of such that alternate regularly and are oriented more or less perpendicular to the generalized perimeter of a laminar structure. See also sawtooth, sawtoothlet, scalloplet (crenule), tooth (dens), toothlet. |
adaxial |
= ventral (not recommended) |
position |
|
On or pertaining to the side or portion of a lateral structure that faces (or would face) toward the bearing axis when (or if) the axis of the lateral structure is (or were) oriented in the same general direction as the bearing axis. |
staminal |
|
position |
|
Upon or otherwise directly associated with the stamens. |
crateriform |
= goblet-shaped |
solid shape |
|
Having a distal, concave, relatively thin-walled, basically hemispherical portion surmounting a much narrower, transversely round, pedestal-like base. |
subsidiary cell |
|
STRUCTURE |
|
One of the cytologically distinctive epidermal cells that are sometimes present in a stomate and that surround and are regularly oriented in relation to the guard cells. |
prophyllar |
|
insertion |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
main stem |
= primary stem; > bole, trunk |
STRUCTURE |
|
The one, or any of the more than one, first-order stem(s), or first-order portion(s) of the collective stem, of a shoot. |
arrangement |
|
CHARACTER |
|
Disposition of equivalent structures with respect to one another (positions/insertions and/or orientations, regarded collectively) within some explicit or implicit standard context. Overlaps conceptually with habit, insertion, orientation, position, and shape. |
short-shoot |
= spur |
STRUCTURE |
|
A first- or higher-order woody stem branch having relatively unelongated internodes, thus proximate nodes, and limited duration of growth, usually branching little if at all; often a main locus of flower production; usually more or less perpendicular to the axis that bears it and resembling a spur projecting from it; sometimes becoming more or less spinose after elongation ceases; esp. in Rosaceae. |
claw |
= unguis |
STRUCTURE |
|
The abruptly much narrower proximal portion, when present, of a laminar structure, esp. a petal; of variable shape itself, but usually attenuate toward the base. |
peripheral |
|
insertion |
|
Upon or otherwise directly associated with the outer surfaces or regions of a three-dimensional structure. Although use of this term in two-dimensional contexts is technically correct, traditionally the term marginal is preferred in such cases. |
di… |
= bi…, two-… |
prefix |
|
Indicating presence of or constitution by two entities of the type denoted by the term's stem; as in diadelphous, dicyclic, dimerous. See also individual entries for terms with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination; and also double-… (bi…, twice-…). |
laciniate |
= slashed; < cut, incised, lacerate, torn |
plane shape |
|
Having relatively close, more or less straight lines of separation exending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented). |
receptacular bract |
= pale, palea, palet |
STRUCTURE |
|
A small papery (chartaceous) to membranous bract borne on the compound receptacle (torus) of a capitulum (head) in Asteraceae (Compositae). |
ear |
= auricle |
STRUCTURE |
|
A small, rounded, lateral lobe at the base of a laminar structure, lying in more or less the same plane as the remainder of the lamina. |
exudation |
|
CHARACTER |
|
Discharged substance, as to type. |
S-shaped 2 |
= sigmoid |
solid shape |
|
Elongate with more or less constant width or diameter and curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |
mushroom-shaped |
= fungiform |
solid shape |
|
Having a cylindric base and a considerably broader, pulvinate distal portion; like the generalized form of a mushroom. |
waxy 2 |
= ceraceous, cereous, waxy |
texture |
|
Having the consistency of wax. |
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. |
haft |
|
STRUCTURE |
|
The narrow portion of a structure that is notably constricted. |
absent |
|
presence |
|
Not occurring within the context in point. |
sporophyll |
= spore leaf; > fertile frond |
STRUCTURE |
|
A leaf or homologous structure that bears sporangia. See also megasporophyll (macrosporophyll, not recommended), microsporophyll. |
…lobate |
? …cleft, …fid, …lobed, …parted, …partite, …segmented |
solid shape |
|
Having the number of lobes indicated by the prefix; as in bilobate. |
