This is a rain forest understorey shrub with wonderfully large leaf proportions. The leaves can be almost as large as a dinner plate, and have a superficial resemblance to the Stinging Tree, particularly Dendrocnides cordifolia.
However, C. tracyanum is not quite as strongly toothed on the leaf margins, and tends to have a light green look, caused by the somewhat felty hairs on their leaves. Perfectly safe to touch.
Of course, the fruits which contrasts with the brightly coloured calyces are quite distinctive of the genus.
