This endemic tree of upland rainforest is at first sight a rather nondescript tree. I had quite a rough time finding out what it was but after knowing it I realized that it can be recognized easily by a number of characters. Firstly, the leaves are alternately arranged and inconspicuously toothed towards the apex. It might tale a bit of close looking to make out the teeth but they are there. Secondly, the leaves have a thick cardboard texture and thirdly the midrib or the leaf stalk will usually have some dark coloration, especially on the leaf undersurface.
This species has three recognized varieties all known as White Hazelwood. The variety gittonsii is the easiest to recognize and can be quite ornamental. It has the largest and the most robust leaves (up to 18cm and certainly larger when in a sapling stage). The leaf midrib is also conspicuously purple on the leaf undersurface, for quite a distance up the leaf blade.
I know much less about the other two varieties but presumably they have smaller in leaf size and var. glaberrima has black to puple leaf stalks on the leaf upperside while in var. pilosiuscula has brown or cream midribs on the leaf underside.
More on this when I find some in flower!
