Naturalised in glasshouse within Robbins Park. Growing with Deparia petersenii subsp. congrua (also naturalised at this site). This fern, which I assume is also a Deparia, resembles D. petersenii subsp. congrua except that it is stouter with glaucescent (not easily seen in these images sorry) more fleshy fronds and has a less pronounced creeping habit. I have only ever seen this fern as a weed in glasshouses and ferneries (and then now rarely so - though it was once very common in the 1970s in the Waikato Auckland area in botanical gardens, glasshouses etc.
