s from the leaf axils. Either singly, or in twos or threes. Flowering usually from October to January, though sometimes as late as Easter. The fruit is an orange capsule, roundish in shape. 3 to 7 mm in diameter. The capsule splits in two, with one to four glossy brown seeds, enclosed in an orange fleshy aril

Description
Commonly seen as a densely dark green shrub two metres tall, though it can occasionally attain heights of 10 to 15 metres with a trunk diameter of 25 cm thick. The trunk is crooked and misshapen but without buttresses. Outer bark greyish brown or grey, fairly smooth but with lenticelLenticel
A lenticel is an airy aggregation of cells within the structural surfaces of the stems, roots, and other parts of vascular plants. It functions as a pore, providing a medium for the direct exchange of gasses between the internal tissues and atmosphere, thereby bypassing the periderm, which would...
