• Leaves glossy green above, dull glaucous below

• A terminal leaflet is seen on the end of the compound leaf

• Leaf stalks vary between 20 mm and no leaf stalk in sub species leptophylla

• 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

• Leaf veins evident on both the upper and lower surfaces; sunken on the top of the leaf, raised below

• It was given its current name in 1894 by German botanist Hermann Harms

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

• Ecology

  • Currawongs eat the fruit

  • The caterpillars of the elderberry panax leaf roller (Cryptoptila australana) eat the leaves
