STRUCTURE |
|
Any lateral structure ontogenetically and anatomically analogous with, and therefore presumably homologous with, but relatively smaller than, a leaf, especially when subtending an inflorescence, other reproductive structure, or portion thereof; putatively, an evolutionarily reduced leaf. |

relief |
|
Having small, conoidal protrusions overall; appearing pimply. |

texture |
|
Firm, relatively light, discontinuous but strongly cohesive, and resilient. |
|
plumose |
= feather-shaped |
solid shape |

STRUCTURE |
|
A whorl of bracts immediately subtending (beneath or outside) a calyx. |
|
scabrous 2 |

relief |
|
Having small, stout, stiff, more or less acute protrusions. |
|
flexuose |
|
course |
|
See flexuous. |
|
small-scalloped |
= crenulate |
margin |
|
Finely scalloped (crenate). See also sawtoothed (serrate), small-sawtoothed (serrulate), small-toothed (denticulate), toothed (dentate). |
|
gummy |
|
texture |
|
Highly viscous and sticky, liquid or more or less deformably solid, sometimes more or less elastic. |
|
stoma 2 (strict sense) pl. stomata |
= stomatal pore |
FEATURE |
|
The aperture between and regulated by the two guard cells of a stomate (stomatal apparatus). |
|
tartareous |
= tartar-like |
relief |
|
Rough and crumbling spontaneously, becoming erose. |
|
xylem |
= wood |
STRUCTURE |
|
The water-conducting and usually main supporting tissue of a plant or portion thereof, characterized by the presence of tracheary elements (tracheids and sometimes vessel elements); the lignified tissue of a plant or component structure, composed almost entirely of secondary tissue, i.e., that derived by secondary or lateral growth from a cambium in structures a season or more old. See also sapwood, heartwood. |
|
multi… |
= many-…, pluri…, poly… |
prefix |
|
Indicating presence of or constitution by a relatively large number of entities of the type denoted by the term's stem; as in multicarpellate, multicellular, multifacial, multiseriate. See also oligo… (few-…). |
|
carpophore 2 |
= columella; < stalk |
STRUCTURE |
|
Any pedestal-like prolongation of a floral receptacle extending beyond the distalmost level of perianth insertion and bearing the gynoecium. |
|
pistillode |
= pistillodium |
STRUCTURE |
|
Any sterile structure deemed to represent a modified pistil, homology being inferred on the basis of structural similarity, ontogeny, and/or position; sometimes nectariferous, sometimes connate with others or adnate to other floral structures. |
|
deca… |
= ten-… |
prefix |
|
Indicating presence of or constitution by ten entities of the type denoted by the term's stem; as in decandrous, decagynous, decalocular. |
|
putrid |
= fetid |
odor |
|
Stinking like rotting flesh. |
|
elastoviscin |
= viscin |
SUBSTANCE |
|
A sticky, elastic material, especially that forming the threads that sometimes connect pollen grains. |
|
ruminate |
= chewed |
relief |
|
Irregularly convoluted, as if chewed. |
|
filamentous |
|
texture |
|
Composed of filiform (thread-like) strands with no intervening tissue. |
|
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. |
