palinactinodromous |
|
venation |
|
Compound actinodromous, with higher-order branch radiations above the level of and similar to the primary one. |
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. |
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. |
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. |
single-veined |
= hyphodromous, one-veined |
venation |
|
Having one median, primary vein and no other venation externally evident. |
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. |
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. |
watery |
|
texture |
|
Liquid and weakly cohesive, flowing freely; like water. This term often implies also transparency. |
oily 2 |
= greasy, oleaginous, unctuous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
stiff |
= rigent, rigid |
texture |
|
Strongly resisting deformation over its length. |
papery |
= chartaceous, papyraceous |
texture |
|
Very thin, flexible, and readily torn; like paper. See also membranaceous (membranous), pergamentaceous (parchment-like). |
oleaginous 2 |
= greasy, oily, unctuous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
waxen 2 |
= ceraceous, cereous, waxy |
texture |
|
Having the consistency of wax. |
medullose |
= pithy |
texture |
|
Loose or spongy internally, denser and firmer externally. |
fibrous |
|
texture |
|
Having tough, woody or sclerotic strands distributed through a softer matrix. |
glutinous 2 |
> mucilaginous, mucous, viscid |
texture |
|
Sticky or slimy. |
waxy 2 |
= ceraceous, cereous, waxy |
texture |
|
Having the consistency of wax. |
gelatinous |
|
texture |
|
Jelly-like; soft, moist, continuously cohesive, texturally homogeneous, somewhat resilient, and easily cut. |
weak |
|
texture |
|
Very pliable and unresilient. |
supple |
= flexible, pliable, pliant |
texture |
|
Able to bend over its length and/or breadth without structural disruption. |
crumbling |
= fatiscent; > farinaceous, mealy |
texture |
|
Easily disintegrating in relatively small pieces, either spontaneously or under pressure. |
coriaceous |
= leathery |
texture |
|
Moderately thick, tough, and very pliable. |
callose |
= callous |
texture |
|
Hard-leathery; callose tissue usually is also thicker than comparable adjacent tissue. |
unctuous 2 |
= greasy, oily, oleaginous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
