Hi Patricia, The grid reference that is being used equates to roughly 3m X 3m. It is a borrowed measure for this project. This square in question has Slater's Crimson China, Parkes Yellow Scented China, Humes Blush Tea Scented China and Old Blush all recorded together. The Macarthur Old Blush shares its location with Mevrouw Nathalie Nypels.
The poor little remaining Old Blush is hidden under Humes Blush and Parkes Yellow. Its very spindly and about 60 to 70cm in height.
