|
position |
|
Internodal but close to and directly above the axil(s). |

inflorescence |
Having one or more gaps in an otherwise uniform distribution of flowers or branch units along the main axis. |

architecture |
inflorescence |
Comprising one or more scorpioid cymes. See also cincinnate, helicoid-cymose. |

|
praemorse |
|
apex |
|
Truncate with the distal margin irregular or ragged, as if chewed. |
|
sawtoothlet |
|
STRUCTURE |
|
A diminutive sawtooth. See also scallop (crena), scalloplet (crenule), tooth (dens), toothlet. |
|
lamellate |
|
apex |
laminar structure |
Having two small terminal plates of tissue closely parallel to one another and perpendicular to the plane of the lamina. |
|
knee 1 |
|
STRUCTURE |
|
An abrupt bend in an axial or other elongate structure. |
|
dimidiate |
|
solid shape |
|
Halved, figuratively; bilaterally asymmetric, nearly or wholly lacking one side as implicitly compared with some corresponding bilaterally symmetric structure, real or imagined. |
|
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 ). |
|
spikelet |
|
nominative |
inflorescence |
A compound structure belonging to the penultimate subdivisional order of a sedge or grass inflorescence; consisting of one or more florets (each a diminutive flower subtended by specialized bractlets (bracteoles) called scales or glumes in sedges, lemma and palea in grasses), spicately arranged along a common axis (rachilla), the axis and florets together subtended by one or (usually) two bracts (first and second glumes). The spikelet is usually considered to be the basic unit of inflorescence in Cyperaceae and Poaceae (Gramineae). |
|
cymose |
|
architecture |
inflorescence |
Comprising one or more simple or compound cymes. See also cincinnate, cymulose, dichasiate, helicoid-cymose, monochasiate, rhipidiate, scorpioid-cymose. |
