lancehead-shaped 1 |
= lanceolate |
plane shape |

architecture |
|
Having equivalent constituent parts disposed very near to one another. |
tholiform |
= dome-shaped |
solid shape |
|
Convex overall, broadest at the base, and transversely more or less circular to elliptical throughout. |
sawtoothed |
= serrate |
margin |
|
Having regularly spaced, angular convexities oriented at an acute angle to the generalized perimeter. See also scalloped (crenate), small-scalloped (crenulate), small-sawtoothed (serrulate), small-toothed (denticulate), toothed (dentate). |
orbiculate |
= round; orbicular misapplied |
plane shape |
|
Circular. |
epicalyx pl. epicalyces |
= calyculus |
STRUCTURE |
|
A whorl of bracts immediately subtending (beneath or outside) a calyx. |
square |
|
plane shape |
|
Equilaterally rectangular. |
primary vein |
> costa, midnerve (not recommended), midrib, midvein, rib; >< lateral vein |
STRUCTURE |
|
A strand belonging to the first order of vasculature in a leaf or other basically laminar structure. See also secondary vein, tertiary vein, veinlet. |
bi… 1 |
= di…, two-… |
prefix |
|
Indicating presence of or constitution by two entities of the type denoted by the term's stem; as in bicarpellate, biciliate, bifid, bilocular. 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. |
lunate |
= crescent-shaped |
plane shape |
|
Arcuate, broadest at the middle, and attenuate to acute ends; like the stylized outline of a first-quarter moon. |
foveolate |
= fine-pitted, scrobiculate |
relief |
|
Finely foveate (pitted). |
setose |
= hispid; < bristly |
pubescence |
|
Bearing relatively long and slender, more or less straight, terete, fine-pointed, stiff trichomes. See also setulose (hispidulous, small-bristly). |
suborbicular |
= subglobose, subrotund, subspheric(al), subspheroid(al) |
solid shape |
|
Broadly ellipsoid with a length:width ratio closely approaching 1:1; almost orbicular, slightly longer than broad. |
knee root |
|
STRUCTURE |
|
A specialized secondary root of a wetland tree, a portion of which projects above mean water level and appears to bend as a leg does at the knee, its distalmost portion being anchored in the substrate beneath the water. The knee of the root is commonly regarded as a conduit for gas exchange between root interior and atmosphere, a function whose need is posited on the basis of the highly anaerobic and saturated conditions prevailing in wetland substrates. |
club-shaped |
= clavate |
solid shape |
|
Elongate and basically round in transverse section, the diameter greatest at or near a blunt apex, thence attenuate toward the base, the degree of taper greatest between the middle and the upper quarter. |
rank |
|
FEATURE |
|
A sequence of lateral structures arising from the same axis at successive points along its length and diverging from it in the same direction. |
…ranked |
= …stichous |
arrangement |
|
Disposed along the axis in the number of distinct ranks indicated by the prefix; as in two-ranked. |
exocarp |
= epicarp |
STRUCTURE |
|
The outermost tissue layer of a pericarp. |
calyx tube |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a synsepalous (gamosepalous) calyx proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the sepals. |
mucous 2 |
= mucilaginous; < glutinous |
texture |
|
Slimy. |
viscin |
= elastoviscin |
SUBSTANCE |
|
A sticky, elastic material, especially that forming the threads that sometimes connect pollen grains. |
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. |
gynandrium pl. gynandria |
= column, gynostemium |
STRUCTURE |
|
A central floral structure consisting of the partly to wholly fused (connate and adnate) androecium and gynoecium; esp. in Orchidaceae. |
spiral 3 |
= helical |
course |
|
Curving with constant or regularly increasing radius from one end to the other through three dimensions. |
linear 2 |
|
plane shape |
|
Elongate and narrow with the sides more or less straight and parallel over most of its length. |
