Overlooked and Underrated

Smyrell's Clausena at Peacehaven

The Clausena smyrelliana, Smyrell’s Clausena or Greg’s Wampi (a great name in my opinion) was overlooked by Europeans until the 1990s. It was brought to the botanical world’s attention by Greg Smyrell, a Queensland botanist. They have been found in the rainforest only in a very restricted part of the Maryborough/ Bundaberg region. The first one was discovered by Greg Smyrell in the Hervey Bay area, then a few more in 2005 in a small patch at Mon Repos. Unfortunately the Bundaberg trees died, possibly due to the drought, and now only one, the original, is known to exist in the wild.

Why aren’t we shouting this from the rooftops? It must be one of the rarest plants in the wild.

Luckily it has been easy to cultivate, and Peacehaven has its own beautiful specimen. It belongs to the Rutaceae or citrus family. The edible fruit is said to have a citrus flavour and the crushed leaves smell of lemon.

It’s a fast growing but small tree, about 7-8 m in the wild, probably smaller in your garden. It has a dense canopy of shiny, dark green leaves giving a very textural appearance. The flowers are tiny though showy in clusters above the leaves. The fruit when ripe are white.

A close cousin is the Clausena lansium or Wampi from Asia. Its fruit is very sweet and popular in that part of the world fresh or cooked in pies or jams.
