herbaceous 2 |
|
texture |
|
Composed entirely of relatively soft, non-woody (unlignified) tissues derived from primary growth. |
|
hard |
= indurate(d) |
texture |
|
Yielding only under strong pressure; not deformable without internal structural disruption. See also callose (callous), hard-coated (corticate), hard-stemmed (sclerocaulous). |
|
pliant |
= flexible, pliable, supple |
texture |
|
Able to bend over its length and/or breadth without structural disruption. |
|
hard-coated |
= corticate |
texture |
|
Having a hard exterior layer and a distinct, softer interior. |
|
fleshy |
= carnose, sarcous |
texture |
|
Fairly firm and dense, juicy or at least moist, and easily cut. |
|
mucous 2 |
= mucilaginous; < glutinous |
texture |
|
Slimy. |
|
crustaceous |
= crusty |
texture |
|
Thin, dry, hard, and brittle. |
|
succulent |
|
texture |
|
Herbaceous and juicy, often thickened (incrassate). |
|
hard-stemmed |
= sclerocaulous |
texture |
plant |
Having hard, relatively dry, but essentially herbaceous main stems that contain a significant proportion of sclerotic tissue or fibers. |
|
loose 2 |
|
texture |
|
Soft overall, discontinuously and only weakly cohesive. |
|
ceraceous 2 |
cereous, waxen, waxy |
texture |
|
Having the consistency of wax. |
|
fleshy-stemmed |
= sarcocaulous |
texture |
plant |
Having main stems that are fleshy (carnose, sarcous). |
|
watery |
|
texture |
|
Liquid and weakly cohesive, flowing freely; like water. This term often implies also transparency. |
|
crusty |
= crustaceous |
texture |
|
Thin, dry, hard, and brittle. |
|
oily 2 |
= greasy, oleaginous, unctuous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
|
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. |
|
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. |
|
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. |
|
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. |
|
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. |
|
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. |
|
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. |
