Bluntly angular; having an angular proximal portion whose generalized sides intersect at an angle of 90° or more. |
|
venation |
|
CHARACTER |
|
Configuration of laminar vasculature as to its hierarchical organization and the dispositions of component orders. For descriptive purposes, the orders of vasculature are ranked with reference only to the lamina in point, irrespective of rank within any larger vascular context. |
|
margin |
|
CHARACTER |
|
Configuration of all or part of the periphery of a planate structure, sometimes referred to as though it were discrete and an entity in its own right for descriptive purposes. The extent of the area considered to pertain to the margin in a given case is, of necessity, subjectively determined. As a general rule, peripheral concavities that do not exceed 1/5 the distance from the generalized edge to the center or main axis of the structure are considered components of marginal configuration, deeper concavities being considered components of overall shape. The margin is sometimes considered to be only the infinitely thin boundary itself, and such a definition is probably the one most technically correct from the standpoint of geometry and general usage. However, it is inconsistent with traditional usage in descriptive botany, which treats the margin as an entity of substance both semantically and conceptually. The semantic antecedent of some descriptors is "margin," whereas the antecedent of others is the structure as a whole (e.g., leaf). |
|
odor |
|
CHARACTER |
|
Olfactory stimulation. |
|
sculpture |
= relief |
CHARACTER |
|
General topographic aspect of a surface. Overlaps conceptually with solid shape. |
|
texture |
|
CHARACTER |
|
Substantial properties. Overlaps conceptually with solid shape, as to thickness. |
|
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." |
