torus 2 pl. tori |
= receptacle |
STRUCTURE |
|
The short, expanded, compound axial structure surmounting a peduncle and basal to two or more flowers, or to the florets of a capitulum (head) in Asteraceae (Compositae), where it may bear paleae (receptacular bracts), scales, bristles, trichomes, or subulate enations, and may be smooth or variously pitted (alveolate, foveolate). |
|
arching |
= recurved |
orientation |
|
Curving backward or downward. |
|
deflexed |
= reflexed |
orientation |
|
Abruptly bent outward (abaxially), downward, or backward at some point along its length. |
|
actinomorphic |
= regular |
architecture |
perianth, calyx, corolla |
Radially symmetric; divisible into two essentially equal portions along any median longitudinal plane. |
|
sculpture |
= relief |
CHARACTER |
|
General topographic aspect of a surface. Overlaps conceptually with solid shape. |
|
distant |
= remote |
arrangement |
|
Disposed relatively far from one another along the axis. |
|
kidney-shaped 1 |
= reniform |
plane shape |
|
Broadly elongate and arcuate, each end bluntly rounded; like the generalized outline of the broad face of a human kidney. |
|
kidney-shaped 2 |
= reniform |
solid shape |
|
Thickly elongate and arcuate, circular or compressed-circular in transverse section, each end bluntly rounded; like the generalized shape of a human kidney. |
|
creeping |
= repent |
habit |
axis |
Procumbent and rooting adventitiously at intervals along its length. |
|
netted 2 |
= reticulate |
coloration |
|
Having a pattern of interconnected fine lines of contrasting hue and/or intensity. |
|
netted 3 |
= reticulate |
relief |
|
Having prominulous, more or less regularly interconnected lines. |
|
rootstock |
= rhizome |
STRUCTURE |
|
An underground, usually horizontal stem, often superficially resembling a root but easily distinguished by the presence of nodes, from which it branches exogenously to produce the aboveground portion(s) of the shoot. |
|
rhombic |
= rhombate |
plane shape |
|
Broadest at the middle and more or less regularly attenuate to either end, the sides angled at the middle and more or less straight from there to either end. |
|
rhombate |
= rhombic |
plane shape |
|
Broadest at the middle and more or less regularly attenuate to either end, the sides angled at the middle and more or less straight from there to either end. |
|
diamond-shaped |
= rhomboid |
solid shape |
|
Transversely square, broadest and longitudinally angular at the middle, regularly attenuate to angular ends, all faces essentially plane; like the stylized shape of a diamond. |
|
costa pl. costae |
= rib; > midnerve (not recommended), midrib, midvein; >< lateral vein |
STRUCTURE |
|
A primary vein of a laminar structure, having a longitudinal course, either medial or lateral, often prominent. See also secondary vein, tertiary vein, veinlet. |
|
costate |
= ribbed |
architecture |
laminar structure |
Having one or more costae (ribs). |
|
stiff |
= rigent, rigid |
texture |
|
Strongly resisting deformation over its length. |
|
rigid |
= rigent, stiff |
texture |
|
Strongly resisting deformation over its length. |
|
dextrorse |
= rightward |
orientation |
|
Directed to the right, relative to the direction of growth along an explicit or implicit axis of reference. See also sinistrorse (leftward). |
|
rigent |
= rigid, stiff |
texture |
|
Strongly resisting deformation over its length. |
|
annular |
= ring-shaped |
solid shape |
|
More or less evenly tubular in a closed circle; like a ring or doughnut. |
|
radix pl. radices |
= root |
STRUCTURE |
|
A vascularized axis that is not internally differentiated into nodes and internodes and that branches endogenously, serving for anchorage, absorption and/or storage; collectively, all those portions of a plant body not belonging (anatomically) to the shoot. See also adventitious root, climbing root, diffuse root, knee root, primary root, prop root, secondary root, stilt root. |
|
radicate |
= rooted |
architecture |
plant |
Having one or more roots. |
|
radicant |
= rooting |
architecture |
structure |
Developing adventitious roots; esp. stems or leaves. |
