flower_anther_connective_extension

Label: Connective extension (apical)
Entity URI: https://w3id.org/APD/traits/trait_0012414
Type: categorical
Definition: An androecium morphology trait [TO:0000994] which is whether anthers [PO:0009066] have protrusions [NCIT:C50710] that extend above the two theca [PO:0009069] (pollen [PO:0025281] sacs), and, if present, the shape [PATO:0000052] and the relative length [PATO:0000122] of the protrusion relative to the length of the entire anther.;Apical (distal) connective extensions (also called 'distal connective protrusions') are sterile anther structures that distally extend beyond the level of the thecae (i.e., the two lateral pairs of pollen sacs of a tetrasporangiate anther).
Additional comments: This trait records both absence or presence of anther connective extensions and also the shape of these extensions in terms of length in relation to the length of the thecae. Definition and trait values derived from Schoenenberger et al. (2020) for their character '314. Connective extension (apical) (D1)'

Allowed values:

value	description
absent	Apical connective extensions are lacking.
long_extension	Connective extension more than a third but less than length of anther; e.g. Idiospermum australiense.
present_general	Apical connective extensions are present but no information on their length relative to the anthers.
short_extension	Connective extension less than a third of the length of anther.
very_long_extension	Connective extension more than length of anther; e.g. Galbulimima belgraveana.
