|
Hard-leathery; callose tissue usually is also thicker than comparable adjacent tissue. |
|
flaccid |

texture |
|
Limp, sometimes appearing withered or shrunken. See also tumid (swollen, turgid). |
|
callous |
= callose |
texture |
|
Hard-leathery; callous tissue usually is also thicker than comparable adjacent tissue. |

|
texture |
|
Soft, light, discontinuous but cohesive, and somewhat resilient. |
|
sclerocaulous |
= hard-stemmed |
texture |
plant |
Having hard, relatively dry, but essentially herbaceous main stems that contain a significant proportion of sclerotic tissue or fibers. |
|
sarcocaulous |
= fleshy-stemmed |
texture |
plant |
Having main stems that are sarcous (carnose, fleshy). |
|
viscid 2 |
< glutinous |
texture |
|
Sticky. |
|
sarcous |
= carnose, fleshy |
texture |
|
Fairly firm and dense, juicy or at least moist, and easily cut. |
|
granular |
= granulate, granulose |
texture |
|
Composed of grain-like particles; loose, dry, and coarsely particulate. |
|
osseous |
= bony |
texture |
|
Very hard and rather brittle, like bone. |
|
brittle |
= friable |
texture |
|
Dry, firm and easily broken. |
|
granulate |
= granular, granulose |
texture |
|
Composed of grain-like particles; loose, dry, and coarsely particulate. |
|
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. |
|
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. |
|
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. |
|
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. |
|
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. |
|
cladodromous |
|
venation |
|
Having a single median primary vein that branches to either side along its length, the secondary veins running thence toward the margin, but freely ramifying and becoming indistinct before reaching it. |
|
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. |
|
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. |
|
parallelodromous |
|
venation |
|
Having two or more primary veins that run more or less parallel to one another over most of the laminar length and converge near the apex. |
|
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. |
