That's very helpful Peter, thanks. The Weinmannia is at Otari Reserve as was the Nestegis lanceolata. As I am getting to grips with the native plants I am hampered a little by only seeing what I can find in Wgtn and for the plants not native to here, that means isolated instances, typically at Otari for natives and the botanical garden for exotics. I am planning to include arrange some trips around the country, any suggestions for good places to visit ?
