hyphodromous |
= one-veined, single-veined |
venation |
|
Having one median, primary vein and no other venation externally evident. |
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. |
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. |
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. |
reticulodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, branching repeatedly, becoming less distinct, and yielding a dense higher-order reticulum near the margin. |
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. |
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. |
bony |
= osseous |
texture |
|
Very hard and rather brittle, like bone. |
ceraceous 2 |
cereous, waxen, waxy |
texture |
|
Having the consistency of wax. |
papyraceous |
= chartaceous, papery |
texture |
|
Very thin, flexible, and readily torn; like paper. See also membranaceous (membranous), pergamentaceous (parchment-like). |
elastic |
|
texture |
|
Resiliently deformable with no loss of structural integrity. |
granular |
= granulate, granulose |
texture |
|
Composed of grain-like particles; loose, dry, and coarsely particulate. |
fatiscent |
= crumbling; > farinaceous, mealy |
texture |
|
Easily disintegrating in relatively small pieces, either spontaneously or under pressure. |
supple |
= flexible, pliable, pliant |
texture |
|
Able to bend over its length and/or breadth without structural disruption. |
herbaceous 2 |
|
texture |
|
Composed entirely of relatively soft, non-woody (unlignified) tissues derived from primary growth. |
granulate |
= granular, granulose |
texture |
|
Composed of grain-like particles; loose, dry, and coarsely particulate. |
cereous 2 |
= ceraceous, waxen, waxy |
texture |
|
Having the consistency of wax. |
mucilaginous 2 |
= mucous; < glutinous |
texture |
|
Slimy. |
granulose |
= granular, granulate |
texture |
|
Composed of grain-like particles; loose, dry, and coarsely particulate. |
soft |
|
texture |
|
Yielding under slight pressure. |
mucous 2 |
= mucilaginous; < glutinous |
texture |
|
Slimy. |
cartilage-like |
= cartilaginous |
texture |
|
Firm, dense, tough, somewhat pliable, and resilient, like human cartilage. |
ligneous |
= woody |
texture |
|
Of or resembling xylem (wood). |
parchment-like |
= pergamentaceous |
texture |
|
Very thin, pliable, and fairly tough; like parchment. See also chartaceous (papery, papyraceous), membranaceous (membranous). |
