Buddleja and Buddleia are both accepted spellings (so far as I
know); and the pronunciation is the same. I don't write or think
Buddleja because I think it's a clumsy word shape, though at least it
should remind me that the E comes after the L :-)

Janet.

AFAICT, according to the rules, Buddleja is the correct spelling, but
I'm not able to find a clear exposition of the situation.

I've been trying (without any luck) to find the source of the name

Linnaeus, after the Adam Buddle, on page 112 of Species Plantarum (1753
edb). You can find a photocopy at gallica.bnf.fr. Buddleia comes from
people who thought Linnaeus had committed a spelling error. But it's not
the only genus with the -ja ending. (Usage of Castilleja dominates over
that of Castilleia.)


IPNI
(International Plant Name Index) has Buddleja, and refers to Kew
Bulletin 349 (1928) for a note on the subject.

Linnaeus used the spelling Buddleja.

The RHS and Kew both use Buddleia on their websites, it seems to be
the more common speling in the UK.

Buddleja seems to be used more often in the USA.
