clavate |
= club-shaped |
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. |
apex pl. apices |
|
CHARACTER |
|
Configuration of the uppermost, distal, or terminal portion of a structure, its extent determined somewhat subjectively in relation to the shape of the structure as a whole. The concept of apex varies from one descriptive context to another, since the apex is not a clearly delimited, morphologically distinct entity. The terms for describing apical condition are not strictly coordinate logically — some are more inclusive than others, some describe conditions involving what can be regarded as appendages, and some refer to the apex in a developmental as well as a strictly topological sense — and precise characterization may require using more than one descriptor. The semantic antecedent of some descriptors is "apex," whereas the antecedent of others is the structure as a whole (e.g., leaf ). |
dextrorse |
= rightward |
orientation |
|
Directed to the right, relative to the direction of growth along an explicit or implicit axis of reference. See also sinistrorse (leftward). |
lacerate |
= cut, incised, torn; > 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). |
terminal |
|
position |
|
Apical and with the same developmental axis as the whole, of which it is the distalmost portion or appendage. |
receptacular |
|
position |
|
Upon, arising from, or otherwise directly associated with the receptacle. |
S-shaped 1 |
= sigmoid |
course |
|
Curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |
muscariform |
= broom-shaped, penicillate |
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. |
waxy 1 |
= ceraceous, cereous, waxen; > caesious, glaucescent, glaucous, pruinose |
coating |
|
Covered with wax or a wax-like substance. |
bifurcate |
< forked, furcate |
plane shape |
|
Having two terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
habit |
|
CHARACTER |
|
General appearance and/or function, usually including explicit or implicit reference to one or more aspects of habitat or other features of the external environment; a logically imprecise traditional category of terms that overlaps conceptually with architecture, arrangement, duration, insertion, location, orientation, position, shape, and texture. |
abrupt |
= truncate |
apex |
|
Having a distal boundary that is generally straight or plane and approximately perpendicular to the central axis. |
sporocarp |
= spore body |
STRUCTURE |
|
A multicellular structure that bears and more or less encloses several to (usually) many sporangia, the latter often aggregated into sori within it See also megasporocarp (macrosporocarp, not recommended), microsporocarp. |
corm |
|
STRUCTURE |
|
A short, thickened, solid, usually subterranean, sometimes fleshy stem base containing stored carbohydrates and serving as a perennating organ. |
lobate |
? cleft, dissected, divided, lobed, parted, partite, segmented |
solid shape |
|
Having one or more component sectors or peripheral protrusions that is/are delimited by concavities in the surface or margin and that is/are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |
fluted |
|
solid shape |
|
Having rounded to angular longitudinal grooves. |
septal |
|
position |
|
Upon or otherwise directly associated with the septum or septa. |
one-… |
= mono…, single-…, uni… |
prefix |
|
Indicating presence of or constitution by one entity of the type denoted by the term's stem; as in one-carpelled, one-loculed, one-seeded. 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. |
pectinate |
= comb-shaped |
plane shape |
|
Finely divided, the divisions slender, oriented more or less perpendicular to the central axis, and resembling the teeth of a comb. |
hydrocyanic |
= almondy |
odor |
|
Pungently fruity like almonds, due to the presence of hydrocyanin or a closely related compound. |
rachis 1 var. rhachis |
|
STRUCTURE |
|
A main or first-order axis of a compound leaf blade. |
versatile |
|
fixation |
|
Attached in a manner allowing free rotation and declination. |

> mucilaginous, mucous, viscid |
texture |
|
Sticky or slimy. |
conduplicate 2 |
= duplicate |
vernation |
|
Each leaf folded sharply inward along its longitudinal axis, the adaxial surfaces of each side facing one another. |
planoconvex |
|
solid shape |
|
Relatively thin with opposite broad faces, one plane and one convex. |
