exudation |
|
Anatomically distinct and producing and exuding a particular substance. |
|
staminode |
= staminodium |
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. |
|
hook-shaped |
= unciform |
solid shape |
|
Very slenderly elongate with a more or less straight proximal portion and a recurved terminal portion, the whole resembling a hook. |
|
surficial |
= superficial |
position |
|
Directly upon the surface of the structure in point. |
|
labium pl. labia |
= lip; > labellum |
STRUCTURE |
|
Any substructure that resembles a lip, especially a portion of a perianth, calyx or corolla; in Lamiaceae (Labiatae) sometimes restricted to the abaxial (lower) of the two corolla lips. |
|
truncate 2 |
|
base |
|
Having a generalized proximal boundary that is more or less straight or plane and approximately perpendicular to the central axis. |
|
watery |
|
texture |
|
Liquid and weakly cohesive, flowing freely; like water. This term often implies also transparency. |
|
androecium pl. androecia |
|
STRUCTURE |
|
The stamen(s), staminode(s), if any, and their ontogenetically associated structure(s), if any, of a single flower, taken collectively. |
|
banner |
= standard, vexillum |
STRUCTURE |
|
The relatively large, erect adaxial (upper) petal in a papilionaceous corolla. |
|
microspore |
|
STRUCTURE |
|
A male spore; a spore of the smaller of the two types produced by the sporophytes of a heterosporous taxon; produced in a microsporangium; giving rise upon germination to a microgametophyte. |
|
calyx pl. calyces |
|
STRUCTURE |
|
Collectively, the sepals of a flower, whether distinct or connate; the outer or proximal envelope of a differentiated perianth, whether the other envelope (corolla) is also actually present or is deemed to be secondarily absent due to evolutionary reduction. |
|
oily 1 |
= greasy, oleaginous, unctuous |
coating |
|
Of a grease- or oil-like film. |
|
crusty |
= crustaceous |
texture |
|
Thin, dry, hard, and brittle. |
|
pruinose |
> caesious, glaucescent, glaucous; < ceraceous, cereous, waxen, waxy |
coating |
|
Covered with a thin, opaque deposit (bloom) of macroscopically indistinguishable waxy particles that rubs off easily. |
|
dorsiventral |
|
architecture |
|
Having structurally distinct abaxial (dorsal) and adaxial (ventral) portions or aspects. |
|
ridge |
|
FEATURE |
|
A very narrow, elongate, relatively low protrusion; esp. on fruits in Apiaceae (Umbelliferae). |
|
falcate 1 |
= sickle-shaped |
plane shape |
|
Elongate and laterally arcuate with the lateral edges more or less concentric, the degree of curvature decreasing distally or not; like the outline of the face of a sickle blade. |
|
furcate |
= forked; > bifurcate |
plane shape |
|
Having two or more terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
|
spot |
= blotch, macula |
FEATURE |
|
An area that differs in color from the rest of a structure's surface, usually due to differing coloration. See also eyespot. |
|
sucker |
> turion |
STRUCTURE |
|
A shoot arising adventitiously from a root or stem below or at ground level. |
|
involute 2 |
|
vernation |
|
Each rolled adaxially from the lateral margins. |
|
trabeculate |
< septate |
architecture |
|
Having one or more trabeculae. |
|
ventrifixed |
|
fixation |
|
Attached on the adaxial side well above the base. |
