craspedodromous, simple- |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins and their branches all running toward and terminating at the margin. |
eucamptodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, the secondary veins upwardly arcuate, gradually becoming indistinct interior to the margin, and serially interconnected by cross-branches without formation of marginal loops. |
palinactinodromous |
|
venation |
|
Compound actinodromous, with higher-order branch radiations above the level of and similar to the primary one. |
mixed-craspedodromous |
|
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. |
anadromous |
|
venation |
|
Having the first lateral vein in each pinna or primary segment of the frond arise from its midvein on the side toward the apex of the frond, the pinnule or secondary segment that it leads to often disproportionately larger than the next distal ones. |
campylodromous |
|
venation |
|
Having several primary and/or strongly developed secondary veins that diverge from a point or small area near the base of the blade and run thence ultimately toward the apex, recurving proximally, arcuate and converging distally, reaching the apex or not. |
simple-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins and their branches all running toward and terminating at the margin. |
semicraspedodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, each secondary vein running thence toward and bifurcate near the margin, one branch terminating at the margin, the other upwardly arcuate and merging with the superadjacent secondary vein, thus forming one of a series of marginal loops. |
hard-coated |
= corticate |
texture |
|
Having a hard exterior layer and a distinct, softer interior. |
rigent |
= rigid, stiff |
texture |
|
Strongly resisting deformation over its length. |
membranaceous |
= membranous |
texture |
|
Extremely thin, pliable, and fairly tough; like animal membrane. See also chartaceous (papery, papyraceous), pergamentaceous (parchment-like). |
hard-stemmed |
= sclerocaulous |
texture |
plant |
Having hard, relatively dry, but essentially herbaceous main stems that contain a significant proportion of sclerotic tissue or fibers. |
fibrous |
|
texture |
|
Having tough, woody or sclerotic strands distributed through a softer matrix. |
oily 2 |
= greasy, oleaginous, unctuous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
crustaceous |
= crusty |
texture |
|
Thin, dry, hard, and brittle. |
papery |
= chartaceous, papyraceous |
texture |
|
Very thin, flexible, and readily torn; like paper. See also membranaceous (membranous), pergamentaceous (parchment-like). |
loose 2 |
|
texture |
|
Soft overall, discontinuously and only weakly cohesive. |
waxen 2 |
= ceraceous, cereous, waxy |
texture |
|
Having the consistency of wax. |
crusty |
= crustaceous |
texture |
|
Thin, dry, hard, and brittle. |
rigid |
= rigent, stiff |
texture |
|
Strongly resisting deformation over its length. |
membranous |
= membranaceous |
texture |
|
Extremely thin, pliable, and fairly tough; like animal membrane. See also chartaceous (papery, papyraceous), pergamentaceous (parchment-like). |
oleaginous 2 |
= greasy, oily, unctuous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
limp |
|
texture |
|
Lacking stiffness in in one or more dimensions, thus drooping or sagging where unsupported. |
horny |
= corneous |
texture |
|
Hard, dense, fine-grained or compactly fibrous, and tough; resembling the substance of animal horn. |
corticate |
= hard-coated |
texture |
|
Having a hard exterior layer and a distinct, softer interior. |
