plane shape |
|
Having four or more intersecting radiate lobes or portions, each distally slender; like the stylized outline of a star. |
|
indurate(d) |
= hard |
texture |
|
Yielding only under strong pressure; not deformable without internal structural disruption. See also callose (callous), corticate (hard-coated), sclerocaulous (hard-stemmed). |

presence |
|
Not occurring within the context in point. |
|
peduncle |
<stalk, stipe (broad sense, not recommended) |
STRUCTURE |
|
The common stalk, when present, of a compound inflorescence or first-order subunit thereof, or of a solitary flower that is deemed to represent an evolutionarily reduced compound inflorescence. |
|
crateriform |
= goblet-shaped |
solid shape |
|
Having a distal, concave, relatively thin-walled, basically hemispherical portion surmounting a much narrower, transversely round, pedestal-like base. |
|
panniform |
< felted |
pubescence |
|
Of closely intertwined, capillate trichomes that form a dense, felt-like mat. See also pannose. |
|
sagittate 2 |
= arrowhead-shaped |
plane shape |
|
Generally triangular, tapering gradually from the base to an acute apex, the base with a relatively large, acute, retrorse lobe to either side; like the outline of the broad lateral face of an arrowhead. |
|
placenta-shaped |
= placentiform |
solid shape |
|
Thickly discoid (disciform); like the generalized form of a human placenta. |
|
central |
= medial, median |
insertion |
|
At, upon, or closely ranged about the structural or symmetrical midpoint or axis. |
|
nodose |
= knobby, knotty |
solid shape |
|
Having nodiform (gongylodate, gongyloid, knob-shaped, knot-shaped) protrusions. See also nodulose. |
|
germination 2 |
|
CHARACTER |
|
The process wherein the contents of a spore begin active growth, exiting the confines of the spore wall via a pore or crack and giving rise to a gametophyte. |
|
runner |
= stolon |
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. |
|
elater 1 |
|
STRUCTURE |
|
An elongate cell with a helical, hygroscopic thickening in its wall, contained within a sporangium, expanding and contracting with changes in humidity and aiding dispersal of the spores; esp. in Hepaticae. |
|
torus 1 pl. tori |
