Label: Fusion of filaments to inner perianth series
Entity URI: https://w3id.org/APD/traits/trait_0012434
Type: numeric
Definition: A floral organ morphology trait [TO:0000862] which is the proportion [PATO:0001470] of the length [PATO:0000122] of the stamen [PO:0009029] (or staminode [PO:0009077]) filaments [PO:0009067] that are fused [NCIT:C124537] to the innermost perianth [PO:0009058] organ [PO:0009008] at anthesis [PO:0009068].;The fusion of filaments with the innermost perianth organs at anthesis on a continuous scale, from 0 (filaments completely free from perianth) to 1 (filaments fused along their entire length with the perianth; the 'entire length' of the filament is defined as the distance between the floral base and the joint between filament and anther).
Additional comments: Partial fusion is recorded using an approximate number between these two extremes (e.g., 0.1 corresponds to basal fusion, 0.5 to fusion along half of the length of perianth parts). If two (or more) stamen whorls (including staminodial whorls) differ in their extent of filament fusion with the perianth, this trait is recorded as a range of values. For example, if the filaments of an outermost stamen whorl are fused, up to 90% of their length, but an inner whorl only up to 50%, the trait is assigned a range of 0.5 to 0.9. The rationale for this is to provide a general trait that allows comparison of fusion among all angiosperms. Definition derived from Schoenenberger et al. (2020) for their character '308. Fusion of filaments to inner perianth series (C1)'
units: {dimensionless}
allowable range: 0 - 1 {dimensionless}
