Only apparently axillary; originally extraaxillary but displaced to the axil by differential growth during development. |
|
acicular 1 |

plane shape |
|
Very slenderly elongate, widest near the middle, and gradually attenuate to an acute apex and a blunter base; like the lateral outline of a needle. |
|

Upon or otherwise directly associated with the septum or septa. |
|
dorsifixed |
|
fixation |
|
Attached on the abaxial side well above the base. |
|
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). |

shoot 1 |
|
STRUCTURE |
|
Collectively, all those portions of a plant body that are anatomically distinct from the root, the component axes differentiated into nodes and internodes, and branching exogenously from the former. |
