• Label: Number of perianth parts
• Entity URI: https://w3id.org/APD/traits/trait_0012464
• Type: numeric
• Definition: A perianth morphology trait [TO:0000275] which is the total count [NCIT:C25463] of perianth [PO:0009058] parts, including sepals [PO:0009031], petals [PO:0009032], and any form of tepal [PO:0009033].;The total number of perianth parts, including sepals, petals, or any form of tepal.
• Additional comments: A value of zero was scored when the perianth is absent. In flowers with perianth whorls fused along their complete length (e.g., Convolvulus), perianth parts are counted based on merism (e.g., if a calyx has 5 distinct sepals and the corolla is entirely fused, then the corolla is often interpreted to consist of five fused petals), anatomy (e.g., number of vascular traces), development (e.g., number of primordia), or comparison with closely related taxa. Definition derived from Schoenenberger et al. (2020) for their character '201. Number of perianth parts (C1)'
• units: {count}
• allowable range: 0 - 1000 {count}
