Knapp, Sandra & Barboza, Gloria & Bohs, Lynn & Särkinen, Tiina. (2019). A revision of the Morelloid Clade of Solanum L. (Solanaceae) in North and Central America and the Caribbean. PhytoKeys. 123. 1-144. 10.3897/phytokeys.123.31738. (Vínculo)
Can this be handled as a simple taxon swap? As I read the paper by Knapp et al. (2019, p. 43 ff), it seems more complicated. They write: "The name S. americanum has been in common use in North America (e.g., Stebbins and Paddock 1949) for what is now known as S. emulans, but more recently (Schilling 1981) the two taxa have been distinguished and the name S. ptychanthum has been used for the taxon for which the oldest name is S. emulans. The type specimen of S. ptychanthum, however, falls within the variation of S. americanum, so is treated as a synonym here."
Los desacuerdos no intencionados ocurren cuando un grupo padre (B) se adelgaza al cambiar un grupo hijo (E) a otra parte del árbol taxonómico, provocando que las Identificaciones existentes del grupo padre sean interpretados como desacuerdos con las Identificaciones existentes del grupo hijo cambiado.
Identification
La ID 2 del taxón E será un desacuerdo no intencionado con la ID 1 del taxón B después del intercambio de ancestros
Si el adelgazamiento del grupo padre provoca más de 10 desacuerdos no intencionados, deberías dividir el grupo padre después de intercambiar el grupo hijo para substituir las identificaciones existentes del grupo padre (B) con identificaciones con las que no esté en desacuerdo,
