axile |
|
placentation |
|
Upon the central axis of a compound, plurilocular ovary. |
prophyllar |
|
position |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
viviparous |
|
reproduction |
|
Producing sexually or asexually generated offspring that begin growth and development while borne upon the parent plant. |
inframedial |
|
position |
|
Slightly below the middle of the structure in point. |
costule |
|
STRUCTURE |
|
A longitudinal primary vein in a diminutive laminar structure, such as the blade of a leaflet, pinna or pinnule; a diminutive costa (rib). |
comose |
|
pubescence |
|
Bearing a prominent single tuft of relatively long and slender, flexible, capillate trichomes (coma). |
supramedial |
|
insertion |
|
Just above the middle of the structure in point. |
dyadal |
|
arrangement |
pollen |
Cohering and shed in pairs, each tetrad having separated into halves. |
pulvinus pl. pulvini |
|
STRUCTURE |
|
A short, cushion-like swelling at the junction of stem and leaf or of inflorescence axis and branch. |
meniscoid |
|
solid shape |
|
Relatively thin with opposite, round, broad faces, one convex and one concave (as viewed externally), the circumferential edge angular or rounded; like a meniscus. See also discoid (disciform), lenticular (biconvex, lens-shaped), patelliform (kneecap-shaped). |
acrocaulous |
|
position |
|
At or very near the stem tip. |
acrodromous |
|
venation |
|
Having two or more primary and/or strongly developed secondary veins that diverge at or above the laminar base and are thence convergently arcuate toward the apex, reaching it or not. |
branchlet |
|
STRUCTURE |
|
A branch of the highest or ultimate order. |
reclining |
|
habit |
axis |
Inserted above substrate level and recurved, the distal portion procumbent. |
transverse 2 |
|
orientation |
|
Perpendicular to the long axis of the context of reference. |
septicidal |
|
dehiscence |
fruit |
Splitting longitudinally into or through the suture(s) in the outer wall and, if present, through the septum(-a) between locules, the latter thus opened indirectly to the outside. |
monopodial |
|
architecture |
axes |
Branching laterally, each axis of each order of branches produced by a single, persistently dominant, apical meristem. See also sympodial. |
caducous |
|
duration |
structure |
Deciduous upon or immediately after emergence, with little or no evident senescence beforehand. |
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. |
decompound |
|
architecture |
|
Comprising two or more orders of equivalent substructural entities; multiply compound. |
involucrate 1 |
|
architecture |
inflorescence |
Subtended by an involucre. |
apiculate |
|
apex |
|
Terminating abruptly in a short, slender, angular tip that is not notably harder or stiffer than the main body of the structure. See also mucronate, mucronulate. |
enation |
|
STRUCTURE |
|
A relatively small outgrowth from an otherwise regular boundary or surface of a larger structure. |
epirhizal |
|
insertion |
|
Upon or arising from the roots. |
divergent |
|
arrangement |
|
Directed at individually different angles from a common point or relatively limited zone of origin, thus farther apart distally than proximally. |
