solid shape |
|
Relatively thin with opposite, round, broad faces, one convex and one concave (as viewed externally), the circumferential edge angular or rounded; like a meniscus. See also discoid (disciform), lenticular (biconvex, lens-shaped), patelliform (kneecap-shaped). |
claw |

STRUCTURE |
|
The abruptly much narrower proximal portion, when present, of a laminar structure, esp. a petal; of variable shape itself, but usually attenuate toward the base. |

STRUCTURE |
|
Any longitudinal segment of a fruit wall delimited by lines of dehiscence. |

= balding |
pubescence |
|
Becoming glabrous (bald, psilate) with age. |
di… |
= bi…, two-… |
prefix |
|
Indicating presence of or constitution by two entities of the type denoted by the term's stem; as in diadelphous, dicyclic, dimerous. See also individual entries for terms with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination; and also double-… (bi…, twice-…). |
beak 1 |
= rostrum |
STRUCTURE |
|
A relatively long, tapering, more or less rigid and pointed enation or termination. |
surface |
|
FEATURE |
|
The exterior or bounding area or layer of any structure, regarded as being infinitely thin; usually described as to relief, reflectance, and/or vesture. |
epigeous |
= epigeal |
location |
|
Upon or very near the surface of the ground; esp. of cotyledons following seed germination. |
rhizophore |
|
STRUCTURE |
|
A stem branch that bears no leaves and from which roots eventually arise; esp. in Selaginellaceae. |
notch |
= emargination |
FEATURE |
|
A relatively small, acute sinus at the distal end of a laminar structure. |
staminodium pl. staminodia |
= staminode |
STRUCTURE |
|
Any sterile structure deemed to represent a modified stamen, homology being inferred on the basis of structural similarity, ontogeny, and/or position; sometimes petaloid, sometimes nectariferous, sometimes connate with others or adnate to other floral structures. |
pitcher |
= ascidium, pitcher blade |
STRUCTURE |
|
A pitcher-shaped (ascidiform) leaf blade, sometimes lidded (operculate), usually carnivorous; esp. in Nepenthaceae, Sarraceniaceae. |
calceolate |
= slipper-shaped |
solid shape |
|
Relatively thin-walled with an essentially hollow interior that is open on one side at the broader end. |
torn |
= cut, incised, lacerate; > laciniate, slashed |
plane shape |
|
Having straight to irregular lines of separation extending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented). |
fimbria pl. fimbriae |
= fringe |
STRUCTURE |
|
A marginal series or cycle of regular, slender, closely adjacent, more or less flexible divisions or protrusions, when treated as an aggregate structure. |
chamber (not recommended) |
= cell (not recommended), locule |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit or other organ; not necessarily having any evolutionary integrity. |
scar |
|
FEATURE |
|
A discontinuity in surface color and/or relief due to abscission of a structure formerly borne there. |
paleaceous |
= chaffy |
pubescence |
|
Of or bearing small, thin, more or less erect, chartaceous (papery) to membranous, planate trichomes. |
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). |
axillary |
|
position |
|
Within the axil; nodal and at or very close to the vertex of the distal angle between a lateral structure, especially a leaf, and the axis that bears it. |
subvalvate |
|
dehiscence |
|
Incompletely or partly valvate. |
elongate |
|
plane shape |
|
Longer in one dimension than in any other. |
reduced |
|
size |
|
Unusually or unexpectedly small. |
uni… |
= mono…, one-…, single-… |
prefix |
|
Indicating presence of or constitution by one entity of the type denoted by the term's stem; as in unicellular, unifloral, unifoliate. See also entries for particular terms with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. |
furcate |
= forked; > bifurcate |
plane shape |
|
Having two or more terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
