Yet two of those lines had been produced from rust infections present on different Stella plants in different locations.

I guess we should have faith that the researchers exercised care in their acquisitions, but browsing through the database here, it appears that there are a few different cultivars being offered in the trade as Stella de Oro. It's understandable, Stella was unbelievably popular, and was used by many hybridizers who wanted to work that continuous bloom into their lines. The problem was, many of the seedlings bore an uncanny resemblance to Stella, and it's not unreasonable to suspect that a lot of those seedlings were passed off as Stella, particularly to landscapers and the nurseries who catered to them. Stella also sets plenty of bee pods, and if those seeds germinated in the clumps...
