In Australia the genus Euphorbia L., sensu stricto, is represented by seven indigenous species in three subgenera. One species has been reported from Papua New Guinea and parts of South-east Asia, another from the New Hebrides; the remaining species are endemic to Australia.

Two taxa are described as new species, viz. Euphorbia parvicaruncula and Euphorbia planiticola, and two former species are reduced to infraspecific rank, viz. Euphorbia tannensis subsp. eremophila, and Euphorbia tannensis subsp. eremophila var. finlaysonii.

Observations are made on geographical distributions, interspecific relationships, and chromosome numbers.
