eradicate |
= rootless |
architecture |
plant |
Lacking a root. |
rhizome |
= rootstock |
STRUCTURE |
|
An underground, usually horizontal stem, often superficially resembling a root but easily distinguished by the presence of nodes, from which it branches exogenously to produce the aboveground portion(s) of the shoot. |
rosulate |
= rosetted |
arrangement |
leaves |
Forming a rosette; strongly congested and disposed radially about the main stem at or very near its base, seeming to arise at the same level and often overlapping laterally; esp. in perennial herbs. |
small-beaked |
= rostellate |
apex |
|
Diminutively beaked (rostrate). |
beaklet 1 |
= rostellum |
STRUCTURE |
|
A small beak or rostrum. |
beaklet 2 |
= rostellum |
STRUCTURE |
|
A sterile excrescent stigma lobe protruding between the anther and the functional stigma lobes of a column; sometimes forming one or more viscidia at pollinium maturity; esp. in Orchidaceae. |
beaked |
= rostrate |
apex |
|
Terminating in a relatively long, tapering, more or less rigid point. See also small-beaked (rostellate). |
beak 1 |
= rostrum |
STRUCTURE |
|
A relatively long, tapering, more or less rigid and pointed enation or termination. |
beak 2 |
= rostrum |
STRUCTURE |
|
The inner, horn-like segment of a coronal lobe; esp. in Asclepiadaceae. |
rosetted |
= rosulate |
arrangement |
leaves |
Forming a rosette; strongly congested and disposed in radial symmetry about the main stem at or very near its base, seeming to arise at the same level and often overlapping laterally; esp. in perennial herbs. |
wheel-shaped |
= rotate |
solid shape |
perianth, calyx, corolla |
Having a very short, cupulate tube and a broad, divergent to divaricate limb; resembling a wheel when viewed from the distal end. |
scabrous 1 |
= rough |
pubescence |
|
Of or bearing coarse, stiff, ascending trichomes and markedly rough to the touch. |
scabrous 2 |
= rough, scabrate, scabrid, scabridous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
scabridous |
= rough, scabrate, scabrid, scabrous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
scabrid |
= rough, scabrate, scabridous, scabrous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
scabrate |
= rough, scabrid, scabridous, scabrous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
orbiculate |
= round; orbicular misapplied |
plane shape |
|
Circular. |
paracytic |
= rubiaceous |
architecture |
stomate |
Having one or more subsidiary cells to either side, all oriented parallel to its long axis. |
obsolete (not recommended) |
= rudimentary; > vestigial |
manifestation |
|
Not developing fully and not functional compared with corresponding structures in other taxa. |
corrugate 2 |
= rugose, wrinkled |
relief |
|
Having irregular, narrow ridges or creases, the intervening areas flat or only slightly concave or convex, appearing overall as though crumpled and then spread out. See also rugulose. |
chewed |
= ruminate |
relief |
|
Irregularly convoluted, as if chewed. |
stolon |
= runner |
STRUCTURE |
|
A slender stem that grows horizontally upon or just beneath the ground surface, rooting at the nodes and giving rise to erect shoot segments at some nodes and/or at its apex. |
stoloniferous |
= runnering, sarmentose |
architecture |
plant |
Producing stolons (runners), by means of which it propagates vegetatively. |
sarmentose |
= runnering, stoloniferous |
architecture |
plant |
Producing stolons (runners), by means of which it propagates vegetatively. |
sigmoid 1 |
= S-shaped |
course |
|
Curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |
