stigma pl. stigmata, stigmas |
|
STRUCTURE |
|
An exposed, localized portion of a pistil that retains deposited pollen and stimulates its germination, the pollen tubes then growing through or along it toward the ovule(s). |
canaliculate |
= channeled |
solid shape |
|
Having a longitudinal, transversely rounded depression; esp. a petiole or petiolule. |
lumen pl. lumina |
|
FEATURE |
|
A space enclosed by the wall(s) or membrane(s) of a structure. |
suprabracteal |
|
insertion |
|
Upon the axes, each directly above (distal to) and very near a point of bract insertion. |
crown-shaped |
= coroniform |
solid shape |
|
Shortly and broadly tubular overall, circumferentially continuous at the base, distally so or not; like a monarch's crown. |
oily 1 |
= greasy, oleaginous, unctuous |
coating |
|
Of a grease- or oil-like film. |
prickle |
|
STRUCTURE |
|
Any unvascularized spine-like enation originating in the epidermis, cortex, or mesophyll of any shoot part. See also spine, thorn. |
diffuse root |
> fibrous root |
STRUCTURE |
|
Any member of a dense system of adventitious, slender roots that arise from the base of a main stem and functionally replace an evanescent primary root. |
mucilaginous 2 |
= mucous; < glutinous |
texture |
|
Slimy. |
tooth pl. teeth |
= dens |
STRUCTURE |
|
One of a series of regularly spaced, angular, marginal convexities oriented more or less perpendicular to the generalized perimeter of a laminar structure. See also sawtooth, sawtoothlet, scallop (crena), scalloplet (crenule), toothlet. |
erose 2 |
= eroded |
relief |
|
Appearing as if chewed or gnawed; having very irregular localized deviations from its generalized line. |
limp |
|
texture |
|
Lacking stiffness in in one or more dimensions, thus drooping or sagging where unsupported. |
barbate |
= bearded |
pubescence |
|
Having one or more limited sectors bearing fairly long, erect, flexible, capillary trichomes. |
fine-pitted |
= foveolate, scrobiculate |
relief |
|
Finely pitted (foveate). |
scar |
|
FEATURE |
|
A discontinuity in surface color and/or relief due to abscission of a structure formerly borne there. |
leaf 2 pl. leaves |
= microphyll |
STRUCTURE |
|
A small, lateral, leaf-like enation that, evolutionarily, is not a true leaf, i.e., whose vasculature, if any, consists of only a single median strand not ontogenetically integral with the vasculature of the bearing stem and not associated with leaf gaps in the stele of the stem; in Psilotophyta, Lycopodiophyta, Equisetophyta. |
subtending |
|
position |
|
Arising from the axis just below and very near to the base of some other specified lateral structure. This term is meaningless if the structure that is subtended is not indicated. |
zig-zag |
= flexuous |
course |
|
Having alternating angular bends to either side, more or less straight between the bends. |
stalkless |
= exstipitate, sessile, unstalked |
architecture |
|
Lacking a stalk, thus inserted ("sitting") directly upon the bearing structure. |
oblanceoloid |
= oblanciform |
solid shape |
|
Inversely lanceoloid (lancehead-shaped, lanciform). |
pluri… |
= many-…, multi…, 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 plurilocular, pluriseriate. See also oligo… (few-…). |
silky |
= sericeous |
pubescence |
|
Of or bearing long, fine, appressed, capillate trichomes and like silk to the touch. |
tessellate 2 |
= checkered |
relief |
|
Having a pattern of regularly disposed squares marked by raised or depressed vasculature. |
epicalyx pl. epicalyces |
= calyculus |
STRUCTURE |
|
A whorl of bracts immediately subtending (beneath or outside) a calyx. |
…whorled |
= …cyclic, …seriate, …verticillate |
arrangement |
|
Disposed in the number of whorls (cycles, series, verticils) indicated by the prefix; as in three-whorled, 1-whorled. |
