Distribution and ecology

Only found in NE Qld where it occurs between Einasleigh in the north and  Dysart and Clermont to the south. It is usually associated with sandstone or laterite in Eucalypt woodland or Acacia shirleyi forest.


Confused with S. ferocissimum and S. parvifolium of the Ferocissimum group of subgen. Leptostemonum  in the past, because of an overall similarity in appearance. Both of these species have red fruits rather than the green with dark green streaks of S. galbinum and the fruits are less than 10 mm wide for the red-fruited species, while they are more than 10 mm wide for S. galbinum. S. parvifolium usually has wider (0.5-3.5 cm) leaves than the other two species (0.2-0.7 cm).

The closest relationships of S. galbinum are thought to lie with S. amblymerum. The species differ by the

Both species were treated by Bean (2004) as members of the S. macoorai group of subgen. Leptostemonum.

Derivation of epithet

From the Latin galbinus, yellowish, a reference to the yellow-green fruit.
