Tieghemopanax sambucifolius Polyscias sambucifolia, commonly known as elderberry panax or small basswood, is a species of plant native to eastern Australia.

[2] The taxonomy of the small basswood has been reviewed, resulting in the recognition of three sub species: sambucifolia, decomposita and leptophylla.

[2] Elderberry panax grows to 11 metres tall with a trunk diameter of 20 cm at Errinundra National Park and Otway National Park in the state of Victoria.

Leaf shape varies between ovate or elliptic to broad-elliptic in sub species sambucifolia.

However the sessile leaflets of sub species leptophylla are oblong linear and somewhat curved (falcate) in shape.

Leaf formation is two-pinnate or rarely three-pinnate in sub species decomposita.

The fruit is an edible globose mericarp, 4 to 6 mm long and mauve or blue in colour.
