autonymy hierarchy

I suggest, as John McNeill has done, that you read Article 11.6.  The
case below is covered identically (but the names are real!) in Ex. 20
with Heracleum sibiricum L. (1753).

When a subspecies is named, such as Heracleum sibiricum lecokii, the
remainder of the species receives a subspecific name automatically, namely,
Heracleum sibiricum sibiricum.  Any and all new subspecific names are
created by deductions from Heracleum sibiricum sibiricum (just as H.s.
lecokii was).

If the name Heracleum sibiricum is sunk to a subspecific level under
another species, say under Heracleum sphondylium, then new subspecific
autonym is created, Heracleum sphondylium sphondylium, and H. sibiricum
becomes, automatically, Heracleum sphondylium sibiricum.

See page 17, Article 11.6 for the original discussion.  It is quite clear.
