gum |
|
SUBSTANCE |
|
A highly viscous and sticky exudate that becomes more or less elastic and/or deformably solid upon drying. Overlaps conceptually with latex. |
viscin |
= elastoviscin |
SUBSTANCE |
|
A sticky, elastic material, especially that forming the threads that sometimes connect pollen grains. |
resin |
|
SUBSTANCE |
|
A substance of high molecular weight consisting of organic acids, esters, and/or terpenes, produced within plant tissue and exuded from wounds as a liquid that hardens to an amorphous glassy state upon exposure. |
latex pl. latices, latexes |
|
SUBSTANCE |
|
A moderately viscous and sticky exudate, often milky, sometimes otherwise colored or clear. Overlaps conceptually with gum. |
elastoviscin |
= viscin |
SUBSTANCE |
|
A sticky, elastic material, especially that forming the threads that sometimes connect pollen grains. |
farina pl. farinae, farinas |
|
SUBSTANCE |
|
A dry, meal- or flour-like covering. |
sap |
|
SUBSTANCE |
|
Generally, the fluid content of a plant body; more precisely, the sugary fluid transported by the phloem. |
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). |
leathery |
= coriaceous |
texture |
|
Moderately thick, tough, and very pliable. |
brittle |
= friable |
texture |
|
Dry, firm and easily broken. |
sarcocaulous |
= fleshy-stemmed |
texture |
plant |
Having main stems that are sarcous (carnose, fleshy). |
hard-coated |
= corticate |
texture |
|
Having a hard exterior layer and a distinct, softer interior. |
chartaceous |
= papery, papyraceous |
texture |
|
Very thin, flexible, and readily torn; like paper. See also membranaceous (membranous), pergamentaceous (parchment-like). |
sclerocaulous |
= hard-stemmed |
texture |
plant |
Having hard, relatively dry, but essentially herbaceous main stems that contain a significant proportion of sclerotic tissue or fibers. |
sarcous |
= carnose, fleshy |
texture |
|
Fairly firm and dense, juicy or at least moist, and easily cut. |
hard-stemmed |
= sclerocaulous |
texture |
plant |
Having hard, relatively dry, but essentially herbaceous main stems that contain a significant proportion of sclerotic tissue or fibers. |
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. |
pithy |
= medullose |
texture |
|
Loose or spongy internally, denser and firmer externally. |
herbaceous 2 |
|
texture |
|
Composed entirely of relatively soft, non-woody (unlignified) tissues derived from primary growth. |
mucilaginous 2 |
= mucous; < glutinous |
texture |
|
Slimy. |
viscid 2 |
< glutinous |
texture |
|
Sticky. |
gummy |
|
texture |
|
Highly viscous and sticky, liquid or more or less deformably solid, sometimes more or less elastic. |
limp |
|
texture |
|
Lacking stiffness in in one or more dimensions, thus drooping or sagging where unsupported. |
bony |
= osseous |
texture |
|
Very hard and rather brittle, like bone. |
