|
sagittate 1 |
= arrowhead-shaped |
base |
laminar structure |
Having two retrorse, generally triangular lobes, one to either side. |

|
halberd-head-shaped 1 |
= hastate |
base |
laminar structure |
Having two generally triangular lobes, one to either side, oriented more or less perpendicular to the central axis. |
|
obtuse 2 |
= blunt |
base |
|
Bluntly angular; having an angular proximal portion whose generalized sides intersect at an angle of 90° or more. |
|
eared |
= auriculate |
base |
laminar structure |
Having two small, rounded, lateral lobes, one to either side, that lie in more or less the same plane as the remainder of the lamina. |
|
blunt 2 |
= obtuse |
base |
|
Bluntly angular; having an angular proximal portion whose generalized sides intersect at an angle of 90° or more. |
|
tailed 2 |
= caudate |
base |
|
With one or more relatively slender, retrorse basal enations or appendages. |
|
position |
|
CHARACTER |
|
Location or disposition with reference to some dissimilar structure(s) or larger context. The lexicons relating to position and insertion overlap to a great degree, since these two morphological concepts are often inseparable in practice. Also overlaps conceptually with arrangement, habit, orientation, and shape. |
|
development |
= ontogeny |
CHARACTER |
|
Mode or pattern of growth and differentiation. |
|
course |
|
CHARACTER |
|
Linear pattern of the centerline through the length of an axis or vein. |
|
vernation |
|
CHARACTER |
|
Disposition of leaves in the bud. |
|
maturation |
|
CHARACTER |
|
Timing of the attainment of functional maturity, sometimes relative to other structures, sometimes as to constituent structures relative to each other. |
|
architecture |
|
CHARACTER |
|
Composite structural configuration as to type, orientation, symmetry, insertion, position, fusion, presence, number, relative size, shape, texture, differentiation, and/or derivation of components and features. Overlaps conceptually with habit. |
|
presence |
|
CHARACTER |
|
Occurrence within the context in point. |
|
reproduction |
|
CHARACTER |
|
Type, morphology, disposition, function and/or dissemination of reproductive structures. |
|
fusion |
|
CHARACTER |
|
Physical connection of equivalent or dissimilar structural entities (as recognized on evolutionary, morphological, anatomical, ontogenetic, and/or topological grounds). Terms that denote the interconnection of equivalent structures are predicated on a single collective subject and suffice in themselves to describe the condition; e.g., "sepals connate." However, those that denote the connection of dissimilar structures require explicit notation of each type of structure involved, in either a compound-subject construction or else a single-subject/object-of-preposition construction; e.g., "stamens and corolla adnate" or "stamens adnate to corolla." Qualifying detail is sometimes appropriate; e.g., "filaments connate basally," "filaments adnate to the petals over their lower halves." |
|
insertion |
|
CHARACTER |
|
Mode or locus of attachment of a structure to some dissimilar bearing structure. The lexicons relating to insertion and position overlap to a great degree, since these two morphological concepts are often inseparable in practice. Also overlaps conceptually with arrangement, habit, orientation, and shape. |
|
coloration |
|
CHARACTER |
|
Hue(s), intensity(ies), and/or pattern (if any) of coloring. When more than one hue and/or intensity is involved, a term describing the pattern of contrast will be applicable, and the description as a whole should be phrased to indicate the particular role of each in the pattern; e.g., "ovaries striate, yellow on green"; "petals pink, spotted yellow basally"; "sepals green, suffused with red". |
|
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 ). |
|
solid shape |
|
CHARACTER |
|
Overall three-dimensional form or aspect(s) thereof. Overlaps conceptually with architecture, arrangement, habit, insertion, orientation, position, relief, and texture (as to thickness). |
|
ontogeny |
= development |
CHARACTER |
|
Mode or pattern of growth and differentiation. |
