floral |
|
insertion |
|
Upon, within, or associated with the flowers. |
pseudopetiole |
|
STRUCTURE |
|
A distinctly constricted, more or less stalk-like, proximal portion of a leaf, evolutionarily derived from the blade, the original petiole reduced to the point of absence or vestigiality; esp. in Poaceae (Gramineae). |
glandular 1 |
|
architecture |
|
Having one or more glands. |
prismatic |
|
solid shape |
|
Uniformly polygonal in transverse section, basally and apically truncate, all faces essentially plane. |
bottom-rooted |
|
habit |
plant |
Aquatic and rooted in the substrate beneath the water. |
hypochilium |
|
STRUCTURE |
|
The proximal portion of a labellum (lip) that has distinct proximal, distal, and sometimes also central parts; in Orchidaceae. See also epichilium, mesochilium. |
homochlamydeous |
|
architecture |
flower |
Having a perianth undifferentiated into distinct proximal and distal envelopes (calyx and corolla); composed of tepals, all essentially alike. |
scarious |
|
texture |
|
Very thin, dry, and not green. |
bulbel |
|
STRUCTURE |
|
A comparatively small bulb branching laterally from a larger, currently primary one. |
intercostal |
|
position |
|
Between the costae. |
induplicate |
|
aestivation |
|
Basically valvate but with each member involute, the lateral abaxial surfaces of adjacent members contiguous. |
lacunate |
|
relief |
|
Having relatively large and deep depressions overall. |
soft |
|
texture |
|
Yielding under slight pressure. |
ciliate |
|
margin |
|
Having fine, hair-like trichomes (cilia) oriented in the general plane of the structure. |
column 2 |
|
STRUCTURE |
|
A fused androecium (connate stamens) closely surrounding but free from the gynoecium; esp. in Malvaceae. |
stipule scar |
|
FEATURE |
|
A scar on a stem or petiole due to abscission of a stipule; having an outline like that of a transverse section through the base of the stipule inserted there; variously disposed, usually in pairs, adjacent to a point of leaf insertion, sometimes confluent with the leaf scar, sometimes confluent with stipule scars associated with an opposite leaf, the two sets of scars then more or less encircling the axis. |
corolla tube 2 |
|
STRUCTURE |
|
The portion of the corolla of a bisexual or staminate disc floret proximal to the level of filament insertion; in Asteraceae (Compositae). |
monadal |
|
arrangement |
pollen |
Shed singly, or essentially so, only loosely and irregularly, if at all, coherent, each original tetrad having separated fully. |
aristate 2 |
|
apex |
pappus scale |
Terminating in one or more awn- or bristle-like appendages. |
actinodromous |
|
venation |
|
Having three or more primary veins that diverge radially from a point at or above the base of the blade and run toward the margin, reaching it or not. |
sub-basifixed |
|
fixation |
|
Attached just above its base. |
disarticulating |
|
architecture |
axis |
Articulate(d) and with the main portions of the whole separating at the joints upon maturity or senescence. |
bark |
|
STRUCTURE |
|
The outermost portion of any shoot or root axis having secondary growth, consisting of all those tissues outside the vascular cambium; sometimes exhibiting zonation into inner, living bark and outer, dead bark; usually described only as to external appearance. |
androgynous |
|
reproduction |
taxon |
Monoecious, each inflorescence having a distal sector with only staminate flowers and a proximal sector with only pistillate ones. |
tomentulose |
|
pubescence |
|
Finely tomentose. |
