In reply to Dorothea's message (above),

The original single-flowered Rosa gallica does still grow wild in France and other parts of Europe. At least I have seen photographs of it from those areas. I would be very interested to receive seed of your dwarf variety of Gallica, as I have read about it. It is apparently a mutant cultivar of R. gallica. There is every possibility that some of this seed could throw back to the original form of gallica. There are not too many problems getting seed from Europe to Australia. Just make sure the seed is perfectly clean and dry. The seed must be placed into packets labelled with the species name and approximate quantity of seed. Keep the quantity low. For large quantities, say 100 seeds, halve the quantity into separate envelopes and send a few days apart.
