margin |
|
Finely sawtoothed (serrate). See also scalloped (crenate), small-scalloped (crenulate), small-toothed (denticulate), toothed (dentate). |
|
gum |
|
SUBSTANCE |
|
A highly viscous and sticky exudate that becomes more or less elastic and/or deformably solid upon drying. Overlaps conceptually with latex. |
|
stoma 1 (broad sense) pl. stomata |
= stomatal apparatus, stomate |
STRUCTURE |
|
A localized functional epidermal unit consisting of a microscopic pore and two encircling specialized cells, the guard cells, which, through changes of turgor pressure in response to environmental conditions, regulate the size of the pore and thus the rates of transpiration and gas exchange through it; the whole surrounded or not by associated, cytologically distinctive epidermal cells, the subsidiary or accessory cells, which, when present, are regularly oriented in relation to it. |
|
impressed |
< sunken |
prominence |
|
Shallowly sunken. |
|
tartar-like |
= tartareous |
relief |
|
Rough and crumbling spontaneously, becoming erose. |
|
xylary |
|
position |
|
Within or otherwise directly associated with the wood. |
|
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. |
|
glaucous |
< ceraceous, cereous, pruinose, waxen, waxy |
coating |
|
Whitish pruinose; covered with a thin, opaque, whitish deposit (bloom) of macroscopically indistinguishable waxy particles that rubs off easily. See also caesious, glaucescent. |
|
staminodium pl. staminodia |
= staminode |
STRUCTURE |
|
Any sterile structure deemed to represent a modified stamen, homology being inferred on the basis of structural similarity, ontogeny, and/or position; sometimes petaloid, sometimes nectariferous, sometimes connate with others or adnate to other floral structures. |
|
horn |
= corniculum |
STRUCTURE |
|
A straight or curved, slenderly conic or conoidal protrusion or terminal portion that resembles an animal horn. |
