The two properties 'Greylands' at Indooroopilly; and 'Astolat' at 96 Kadumba Street, Yeronga, should be checked by Queenslanders for old roses with a resemblance to 'Comtesse de Labarthe'. I can SEE tall roses in that round bed in front of the house in the picture featured in http://www.epa.qld.gov.au/chims/placeDetail.html?siteId=16236

My grateful thanks to Sandie Maclean who keeps feeding me fascinating historical data.
