Having a relatively slender protrusion resembling a spur. |
|
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. |

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

|
manifestation |
|
CHARACTER |
|
Degree or nature of evidence when present within the context in point. |
|
reflectance |
|
CHARACTER |
|
Aspect as to proportion and pattern of incident light reflected from the surface. |
|
aestivation |
|
CHARACTER |
|
Disposition of perianth (undifferentiated), calyx, or corolla members in the bud. |
|
porosity |
|
CHARACTER |
|
Presence and disposition of vessels (pores) in wood (xylem). |
|
relief |
= sculpture |
CHARACTER |
|
General topographic aspect of a surface. Overlaps conceptually with solid shape. |
|
derivation |
|
CHARACTER |
|
Ontogenetic origin. |
|
size |
|
CHARACTER |
|
Nature as to absolute or comparative extent in any one dimension or in area or volume. |
|
coating |
|
CHARACTER |
|
Exudate that covers the surface proper. See also indumentum (vesture), pubescence. |
|
exudation |
|
CHARACTER |
|
Discharged substance, as to type. |
|
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). |
