STRUCTURE |
|
An erect or ascending stem that branches from the base of another at or below the surface of the ground; esp. in Poaceae (Gramineae) and other monocotyledons (Liliidae). |
|
excurrent |
|
architecture |
axis, laminar vein |
Branching laterally such that the initial axis retains its prominence over the length of the structure, the succesive orders of branches relatively smaller. See also deliquescent. |
|
paniculate |
|
architecture |
inflorescence |
Comprising one or more panicles. |
|
tillering |
|
architecture |
plant, stem |
Producing tillers; esp. in Poaceae (Gramineae) and other monocotyledons (Liliidae). |

bark |
Shallowly and distantly fissured, falling away in thin, relatively large patches or sheets. |
|
umbo pl. umbines, umbos |
|
FEATURE |
|
A relatively small, rounded or conical, central protrusion upon an essentially round, broad face. |
|
epipterous |
|
solid shape |
|
Alate with a single terminal wing. |
|
tuberous 2 |
|
architecture |
structure |
Resembling a tuber in shape and texture, but not ontogenetically such; esp. roots. |
|
pericarp |
|
STRUCTURE |
|
The portion of a fruit wall that is derived from the ovary wall; consisting of three more or less distinct tissue layers (exocarp or epicarp, mesocarp, and endocarp) that may or may not differ greatly in structure and/or function; the wall of a fruit, excluding any tissues of extra-ovarian (accessory) origin. |
|
ventrifixed |
|
fixation |
|
Attached on the adaxial side well above the base. |
|
pollinial |
|
arrangement |
pollen |
Polyadal with the grains of individual thecae (pollen sacs), or of fused thecae, compacted and forming tightly coherent masses (pollinia) that constitute the basic dispersal units, these sometimes distally attenuate to a sterile caudicle (translator arm), sometimes united by caudicles in groups of two or more, the caudicle(s) sometimes attached to a viscidium, either directly or through an intervening stipe; esp. in Asclepiadaceae, Orchidaceae. |
|
placentation |
|
CHARACTER |
|
Disposition of the placenta(e) within an ovary. |
|
woody clump |
|
nominative |
plant |
An aggregate of woody main stems that arise from belowground organs derived from a single progenitor; the members of a clump are individually tree- or shrub-like and sometimes become physically separate over time. See also bush, frutex, shrub, subshrub, suffrutex, tree, undershrub. |
|
craspedodromous, mixed- |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, some becoming indistinct before reaching it, others terminating there. |
|
pseudopetiolate |
|
architecture |
leaf |
Having a distinctly constricted, more or less stalk-like, proximal portion that is evolutionarily derived from the blade, the original petiole reduced to the point of absence or vestigiality; esp. in Poaceae (Gramineae). |
|
watery |
|
texture |
|
Liquid and weakly cohesive, flowing freely; like water. This term often implies also transparency. |
|
primocane |
|
STRUCTURE |
|
A biennial or perennial stem before it has begun flowering, when the latter does not occur until at least its second season of growth; esp. in Rubus (Rosaceae). |
|
ramentaceous |
|
pubescence |
|
Of small, fragile, scarious, planate trichomes. |
|
cryptocotyloid |
|
germination |
seed |
Having the cotyledon(s) remaining inside the seed coat. |
|
dimidiate |
|
plane shape |
|
Halved, figuratively; bilaterally asymmetric, nearly or wholly lacking one side as implicitly compared with some corresponding bilaterally symmetric structure, real or imagined. |
|
rhytidomal |
|
position |
|
Within, upon, or otherwise directly associated with the bark. |
|
scar |
|
FEATURE |
|
A discontinuity in surface color and/or relief due to abscission of a structure formerly borne there. |
