"Several genera in the Aizooideae are not monophyletic. The southern African endemics Galenia and Plinthus are nested within Aizoon. Aizoon was considered to be well circumscribed, on account of its apically depressed capsules, as opposed to a convex apex in Aizoanthemum (Chinnock, 1983; Hartmann, 2001). However, Bittrich (1990a) noted similar capsules also for most species of Galenia and Plinthus and pointed out (Bittrich 1990b) that there are no clear characters distinguishing the subgenera of Galenia or delimiting it from Aizoon. Thus, the androecial and gynoecial features used by Adamson (1956) to distinguish Galenia from Aizoon are actually shared by these two genera (Bittrich, 1990b). Characteristic for most species in the Aizoon-clade (incl. Galenia and Plinthus), are the long, often silvery hairs on the leaves, which give their leaves a silvery sheen. Although several species of Galenia (such as G. glandulifera and G. africana) do not possess “hairs”, these are possibly reduced or modified (Bittrich, 1990b). "

Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
