Mr Cormack thinks that the Palomino is probably No 7 of Busbys Spanish collection which he called Machar Mudo from the [indecipherable] whence he procured it, the name having been lost - Bailey supports that the Belas blanco (which name does not occur in Busby) is very likely the "Machar Mudo" - if you have got the "Machar Mudo" from Busbys collection I should feel very much obliged if you would give me a particular description of the vine and its fruit as it might help to clear up this point - I think I have heard that Busbys collection at the Sydney Botanic Garden no longer exists so that we cannot refer back to it.
