FEATURE |
|
A longitudinal depression that is relatively shallow and narrow. |
|

|
Aspect as to proportion and pattern of incident light reflected from the surface. |
|
waisted |
|
solid shape |
|
Constricted in width or breadth at or near the middle of its length. |
|
seed coat |
= testa |
STRUCTURE |
|
The outer protective layer of a seed, developed from the ovular integument(s). |
|
capitate 2 |
= headed |
solid shape |
|
Abruptly enlarged distally to a relatively short, terminal portion that is basically round in transverse section. |
|
abrupt |
= truncate |
apex |
|
Having a distal boundary that is generally straight or plane and approximately perpendicular to the central axis. |
|
indument |
|
STRUCTURE / SUBSTANCE |
|
See indumentum. |
|
floricane |
|
STRUCTURE |
|
A biennial or perennial stem after it has begun flowering, when that does not occur until at least its second season of growth; applied especially to the stems of brambles (Rubus spp.). |
|
pseudopetiole |
|
STRUCTURE |
|
A distinctly constricted, more or less stalk-like, proximal portion of a leaf, evolutionarily derived from the blade, the original petiole reduced to the point of absence or vestigiality; esp. in Poaceae (Gramineae). |
|
lacuna pl. lacunae |
|
FEATURE |
|
A hole or cavity; an empty space surrounded by tissue in two or three dimensions. |
|
tri… 2 |
= thrice-…, triple-… |
prefix |
|
Indicating presence of three hierarchical orders of the type of entity or pattern denoted by the term's stem; as in tripinnate. See also entries for particular terms beginning with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. |
|
lepis pl. lepides |
= squama; < scale, trichome |
STRUCTURE |
|
A relatively thick, planate trichome. See also squamella. |
|
pistillode |
= pistillodium |
STRUCTURE |
|
Any sterile structure deemed to represent a modified pistil, homology being inferred on the basis of structural similarity, ontogeny, and/or position; sometimes nectariferous, sometimes connate with others or adnate to other floral structures. |
|
ellipsoid(al) |
|
solid shape |
|
Elliptic in any median longitudinal section; elongate, transversely circular, broadest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
|
obovate |
|
plane shape |
|
Inversely ovate (egg-shaped). |
|
subterranean |
= hypogeal, hypogeous |
location |
|
Within the ground, beneath its surface. |
|
sepal |
|
STRUCTURE |
|
One of the one or more constituent members of a calyx; usually green and leaf-like, but sometimes with color and/or texture otherwise, sometimes petaloid; may be distinct or else connate with one or more others and/or may be free or else adnate to one or more other floral structures. |
|
fiddlehead |
= crozier |
STRUCTURE |
|
A circinate leaf (frond) prior to full expansion, while still wholly or distally coiled; esp. in Polypodiophyta. |
|
planoconvex |
|
solid shape |
|
Relatively thin with opposite broad faces, one plane and one convex. |
|
cruciate 2 |
= cross-shaped |
solid shape |
|
Having two elongate, basically straight portions intersecting at a point interior to the ends of each. |
|
glandless |
= eglandular |
architecture |
|
Lacking glands. |
|
spurred |
= calcarate |
base |
|
Having a relatively slender protrusion resembling a spur. |
|
venation |
|
CHARACTER |
|
Configuration of laminar vasculature as to its hierarchical organization and the dispositions of component orders. For descriptive purposes, the orders of vasculature are ranked with reference only to the lamina in point, irrespective of rank within any larger vascular context. |
|
scalloped |
= crenate |
margin |
|
Having regularly alternating, rounded convexities and concavities oriented more or less perpendicular to the generalized perimeter. See also sawtoothed (serrate), small-sawtoothed (serrulate), small-scalloped (crenulate), small-toothed (denticulate), toothed (dentate). |
