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. |
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. |
brochidodromous |
|
venation |
|
Having a single median primary vein that branches to either side along its length, the secondary veins incurving strongly near but short of the margin, interconnecting serially, and forming a succession of marginal loops. |
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. |
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. |
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. |
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. |
one-veined |
= hyphodromous, single-veined |
venation |
|
Having one median, primary vein and no other venation externally evident. |
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. |
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. |
