Re: [IGSROBIN] what's in a name?


P. x domesticum is the given botanical name for the hybrids of the Regal or
Martha Washington group. Thus P. x domesticum 'Aztec' . It is not a species,
but a hybrid group and must have the "x" before domesticum. How often do you
see it used? Maybe time has made it redundant with the  breeding since
designation. Primary hybrids, first generation of crossing of two species is
written in the same format so there is plenty of room for confusion.

P.x hortorum is the given name for Zonal group, but the Ivy-leaf group is P.
peltatum, which is a species presumably because it is thought no other
species is involved in the breeding line.

Plain Text e-mail presents a problem, not allowing italic letters. The
correct way to write the name is P. (italics or underlined) x (normal type)
domesticum (italics or underlined) 'Aztec' (normal type, single quotes,
capital initial letter)
