|
Very thin, flexible, and readily torn; like paper. See also membranaceous (membranous), pergamentaceous (parchment-like). |
|
rigid |

texture |
|
Strongly resisting deformation over its length. |
|
succulent |
|

Herbaceous and juicy, often thickened (incrassate). |
|
flexible |
= pliable, pliant, supple |
texture |
|
Able to bend over its length and/or breadth without structural disruption. |
|
bony |
= osseous |
texture |
|
Very hard and rather brittle, like bone. |
|
ceraceous 2 |
cereous, waxen, waxy |
texture |
|
Having the consistency of wax. |
|
oily 2 |
= greasy, oleaginous, unctuous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
|
watery |
|
texture |
|
Liquid and weakly cohesive, flowing freely; like water. This term often implies also transparency. |
|
corneous |
= horny |
texture |
|
Hard, dense, fine-grained or compactly fibrous, and tough; resembling the substance of animal horn. |
|
resinous 2 |
|
texture |
|
Having the consistency of resin. |
|
firm |
|
texture |
|
Yielding under only moderately strong pressure; only slightly deformable without internal structural disruption. |
|
loose 2 |
|
texture |
|
Soft overall, discontinuously and only weakly cohesive. |
|
cereous 2 |
= ceraceous, waxen, waxy |
texture |
|
Having the consistency of wax. |
|
oleaginous 2 |
= greasy, oily, unctuous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
|
crumbling |
= fatiscent; > farinaceous, mealy |
texture |
|
Easily disintegrating in relatively small pieces, either spontaneously or under pressure. |
|
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. |
|
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. |
|
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. |
|
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. |
|
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. |
|
catadromous |
|
venation |
|
Having the first lateral vein in each pinna or primary segment of the frond arise from its midvein on the side toward the base of the frond, the pinnule or secondary segment that it leads to often disproportionately larger than the next distal ones. |
|
one-veined |
= hyphodromous, single-veined |
venation |
|
Having one median, primary vein and no other venation externally evident. |
|
palinactinodromous |
|
venation |
|
Compound actinodromous, with higher-order branch radiations above the level of and similar to the primary one. |
|
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. |
|
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. |
