germination 1 |
|
CHARACTER |
|
The process wherein a dormant embryo resumes active metabolism and growth, the primary root and shoot emerging from the seed coat, the young sporophyte thereupon entering the seedling stage. |
|
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. |
|
nutrition |
|
CHARACTER |
|
Mode of acquiring nutrients. |
|
manifestation |
|
CHARACTER |
|
Degree or nature of evidence when present within the context in point. |
|
reflectance |
|
CHARACTER |
|
Aspect as to proportion and pattern of incident light reflected from the surface. |
|
coating |
|
CHARACTER |
|
Exudate that covers the surface proper. See also indumentum (vesture), pubescence. |
|
exudation |
|
CHARACTER |
|
Discharged substance, as to type. |
|
aestivation |
|
CHARACTER |
|
Disposition of perianth (undifferentiated), calyx, or corolla members in the bud. |
|
porosity |
|
CHARACTER |
|
Presence and disposition of vessels (pores) in wood (xylem). |
|
relief |
= sculpture |
CHARACTER |
|
General topographic aspect of a surface. Overlaps conceptually with solid shape. |
|
derivation |
|
CHARACTER |
|
Ontogenetic origin. |
|
size |

CHARACTER |
|
Nature as to absolute or comparative extent in any one dimension or in area or volume. |
|
tailed 2 |
= caudate |
base |
|
With one or more relatively slender, retrorse basal enations or appendages. |
|
rounded |
|
base |
|
Convex overall and more or less regularly curved. |
|
sheathing 2 |
|
base |
laminar structure |
Terete or involute and closely enclosing the supporting axis for some distance above the point of insertion. |
|
cordate 1 |
= heart-shaped |
base |
laminar structure |
Having two equal, more or less rounded, retrorse lobes, one to either side, overlapping or not, the intervening sinus relatively deep. |
|
concave-tapered 2 |
= attenuate |
base |
|
Gradually diminishing in width or diameter toward the proximal end, the sides longitudinally concave. Corresponds with acuminate for apex shape. |
|
truncate 2 |
|
base |
|
Having a generalized proximal boundary that is more or less straight or plane and approximately perpendicular to the central axis. |
|
hastate 1 |
= halberd-head-shaped |
base |
laminar structure |
Having two generally triangular lobes, one to either side, oriented more or less perpendicular to the central axis. |
|
spurred |
= calcarate |
base |
|
Having a relatively slender protrusion resembling a spur. |
|
oblique 1 |
|
base |
|
Asymmetric about its longitudinal axis. |
|
wedge-shaped 1 |
= cuneate, obtriangular |
base |
laminar structure |
Attenuate with the sides more or less straight and intersecting at an acute angle. |
|
attenuate 1 |
= concave-tapered |
base |
|
Gradually diminishing in width or diameter toward the proximal end, the sides longitudinally concave. Corresponds with acuminate for apex shape. |
|
cuneate 1 |
= obtriangular, wedge-shaped |
base |
laminar structure |
Attenuate with the sides more or less straight and intersecting at an acute angle. |
|
decurrent |
|
base |
laminar structure |
Having the lamina prolonged and adherent to the supporting axis beneath the point of vascular insertion, the prolonged portion termed a sterigma. |
