Billbergia 'Breauteana' is one example.
No one appears to have bothered to check the original description by Ed. Andre in Revue Horticole 1884. Even Baker in his Handbook of the Bromeliaceae 1889 described a plant of B. 'Breauteana' growing at Kew Gardens and did not use the original description! Baker then muddied the water somewhat by suggesting that hybrids between B. speciosa and B. vittata such as B. 'Collevii', 'Joliboisi' and others were similar. 
Note that he said "similar" and there were some 6 different plants over the years called 'speciosa', although in this case we know he was referring to the 'B. amoena' kind! I wrongly assumed that the original description by Andre must have been quite brief and in similar fashion to that in Belgique Horticole 1882 where it shows the parentage of B. 'Collevii' as B. amoena and B. leopoldi ( now known as vittata). I would like to thank Eric Gouda of Utrecht Botanic Gardens for supplying this information and we now know that different clones were used to that for B.'Breauteana'.
So we have many look-a-like plants to choose from.
The name B. 'Breauteana' was on the label of the plant received at the Adelaide Botanic Gardens in the 1960's and a botanical painting was done. 
We have been unable to trace how the plant got to the Adelaide Botanic Gardens. We also know that a very similar plant had been growing in Adelaide for many years before that date and in fact had been reported in NSW at least back to 1945. It was decided that this common and widespread Billbergia should have a name and it was called 'Chas Webb' 1.jpg)
to honour one of the earlier growers of Bromeliads in Australia.
In 1993 when preparing a paper for the Adelaide Bromeliad Conference I noticed the similarities between B. 'Breauteana' and B. 'Chas Webb' and how they can be confused with B. vittata.
In 1996 when at the Orlando Bromeliad Conference I saw a slide which I thought was our Aussie plant but Don Beadle called his plant the very variable B. vittata.
So I decided to get back to basics and Jason Grant, botanist of Maryland University, helped me by providing a photocopy of the original description by Ed. Andre. This was in French! Instead of giving the full description here I will quote the differences between the parents in my translation. "The plant differs from B. pallescens (yet another species now known as amoena) by the blunt and non-sharp leaves, the sparse marginal spines, the scape reflexed and not erect, the compound not simple spike, the flowers pale pink with the blade violet-blue and not pale green with indigo blade.
The plant differs from its mother B. vittata by the more soft leaves, much shorter, of a light green, little banded on the upper part of the leaves, the scape pale, with bracts of a more brilliant sandy-red colour, the sepals of a very pale rose flesh colour and not red, edged with 
brilliant violet. Petals nearly a transparent tube, almost colourless, with brilliant violet indigo blade and not a lively carmine crimson toward the base. Ovary pale green and not reddish."
I am therefore quite certain that Billbergia 'Breauteana' is in Australia under the guise of B. 'Chas Webb'
and strictly speaking B. 'Breauteana' should take precedence but this latter name will persist if only for nostalgic reasons. I also believe that B. 'Breauteana' is in the USA as indicated by Victoria Padilla in her book and not as stated in the Bromeliad Cultivar Registry."
