Thank you Giby for the suggestion of Lasianthus micranthus. Reading about it, it does seem to be very variable. I am not clever enough to understand the technical terminology... so am not sure if this is my shrub or not. I do much better with visual aids and photos!
I have searched on www and found a herbarium specimen from Kew. http://apps.kew.org/herbcat/getImage.do?imageBarcode=K000031632 I cannot see the small semi circular leaflet that was grows on the stem between the pairs of leaves, or the pair of stipules that show on my images. Hmm! Just not sure.......
