Thanks all for the suggestions and comparison photos. MrCym has said that it is Ceres, probably the selection/cultivar 'Girrawheen'. I don't suppose anyone would have a photo for comparison to try to confirm the cultivar? He also mentions in another thread (
http://www.newhorizonorchids.c...) that Ceres 'F.J.Hanbury' is not a true Ceres, so the photos I can find online for that one can't be used.
