Georg Forster is not a major author in the Musaceae but, until his mention here, he has been a neglected one.  Forster did little more than give Linnean binomials to the 16 bananas listed by Rumphius under the general heading Musa domestica; Rumphius gave binomial names to three of them himself. However, Forster was the first post-Linnean author to do so and has some significance as a result. 

Of special significance is Forster's treatment of Rumphius' Pisang Batu sive Bidji which he named Musa x paradisiaca var. granulosa.  Pisang batu is Musa balbisianaIf Forster had recognised Pisang batu as a true species and if he had truly published the name Musa granulosa as a binomial then Musa granulosa would be the "true" name of Musa balbisiana.  However, Forster did not explicitly recognise Pisang batu as a true species.  True, he had some reason for rejecting Linnaeus' name for the plant, Musa troglodytarum but did not say what it was.  Musa troglodytarum L. notoriously conflates Rumphius' Musa uranoscopus and Pisang Batu.  In rejecting Linnaeus' name Forster presumably recognised that there was something wrong with it but he did not make this explicit.  Again, Forster's use of the binomial Musa granulosa does not mean that he thought the plant was a true species.  In fact Forster treated all 16 bananas as "varieties" of Linnaeus' Musa paradisiaca. [Thanks to Prof. J. McNeill for putting me straight on this].
