The scientific name for this stately tree is quite a mouthful. It is also known as Rose Butternut or Bollygum. This tree is probably not going to be easy to differentiate from a Queensland Maple (Flindersia spp.) at a glance. Both Flindersia and Blepharocarya have opposite compound leaves. The leaves of Bollygum are not quite as fleshy but more distinctively, the Bollygum has ‘ribs’ at the base of compound leaf stalk (see picture below) which nearly connects with those of the adjacent leaf.
The flowers are very mango-like, as is typical of the family, but the fruits are quite a thing on their own. Distinctively, there is a fibrous-looking basket-like involucre which surrounds the fruit.
