stellate 1 |
= radiant, radiate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
|
horseshoe-shaped |
= hippocrepiform |
solid shape |
|
Relatively slender and strongly compressed, the whole strongly curved over its length in a plane perpendicular to the direction of compression and forming an incomplete circle, the ends somewhat straighter than the rest and parallel or nearly so; like a horseshoe. |
|
symmetric(al) 1 |
|
architecture |
|
Divisible into essentially equal halves along one or more lines or planes. |
|
ladder-like |

arrangement |
|
Disposed in vertical sequence with long axes horizontal and parallel. |
|
tuberculose 2 |
= tubercular |
solid shape |
|
Comprising small knot-like segments. |
|
androphore |
>< stalk |
STRUCTURE |
|
A stalk or tube that rises above the level of perianth insertion and bears the distinct portions of the androecium from its summit; as in Malvaceae, where the androphore is a tube formed by connation of the filaments. |
|
barbella pl. barbellae |
= barbel |
STRUCTURE |
|
A small barb. |
|
mitre-shaped |
= mitriform |
solid shape |
|
Broadest and transversely round to oval proximally, tapering bilaterally above the middle to a central peak; like a peaked hat or cap. |
|
canaliculate |
= channeled |
solid shape |
|
Having a longitudinal, transversely rounded depression; esp. a petiole or petiolule. |
|
cucullus pl. cuculli |
= hood |
STRUCTURE |
|
A cucullate (cuculliform) structure or component, esp. in an inflorescence or flower. |
|
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). |
|
farinose |
< mealy |
pubescence |
|
Bearing minute, relatively stout trichomes, collectively meal- or flour-like (farinaceous) and easily detached. See also farinaceous. |
|
septum pl. septa |
> dissepiment, replum, trabecula |
STRUCTURE |
|
A topologically and/or texturally distinct wall or partition that separates chambers or locules within an ovary, fruit or sporangium. |
|
galea pl. galeae, galeas |
|
STRUCTURE |
|
A galeate (galeiform, helmet-shaped) sepal or petal in a zygomorphic calyx or corolla, differing markedly in shape from and sometimes partially enclosing the other sepals or petals. |
|
squamate |
= lepidote, squamose; < scaly |
pubescence |
|
Bearing squamae (lepides). See also squamellose. |
|
sulcus pl. sulci |
= colpus, fossula, furrow, groove, vallecula |
FEATURE |
|
An elongate depression that is relatively shallow and narrow. |
|
trapeziform |
|
plane shape |
|
Four-sided and either asymmetrical or bilaterally symmetrical like a triangle truncated distally perpendicular to its central axis. |
|
…verticillate |
= …cyclic, …seriate, …whorled |
arrangement |
|
Disposed in the number of verticils (cycles, series, whorls) indicated by the prefix; as in five-whorled, 3-whorled. |
|
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. |
|
median |
= central, medial |
insertion |
|
At, upon, or closely ranged about the structural or symmetrical midpoint or axis. |
|
bulliform |
|
solid shape |
|
Resembling a blister; broad, relatively thin at the periphery, the lower surface approximately flat, the upper shallowly to strongly convex. |
|
oblong 1 |
|
plane shape |
|
Compressed-elliptic, the sides approximately parallel from near one end to near the other. See also elliptic(al) (oval). |
|
penicillate |
= broom-shaped, muscariform |
solid shape |
|
Having a proximal axis that bears a distal cluster of elongate slender branches or appendages, these variously ascending to erect; like a broom. |
|
crena pl. crenae |
= scallop |
FEATURE |
|
A rounded, marginal convexity or concavity in a series of such that alternate regularly and are oriented more or less perpendicular to the generalized perimeter of a laminar structure. See also crenule (scalloplet), dens (tooth), sawtooth, sawtoothlet, toothlet. |
|
primary axis |
> ray |
STRUCTURE |
|
A main or first-order axis within any specified, uniformly delimited structural context. |
