  The purpose of this short note is to highlight a particular phenomenon which
concerns the Higgs branch of a certain family of 4d N = 2 theories with SO(2N)
flavour symmetry. By studying the Higgs branch as an algebraic variety through
Hilbert series techniques we find that it is not a single hyperkahler cone but
rather the union of two cones with intersection a hyperkahler subvariety which
we specify. This remarkable phenomenon is not only interesting per se but plays
a crucial role in understanding the structure of all Higgs branches that are
generated by mesons.
