PICRODENDRACEAE (formerly known as part of Euphorbiaceae) 3:629
Picrodendraceae is a small family characterised by having only one perianth whorl and ovaries with (usually) two ovules per chamber.  In Tasmania the family has two genera,  Micrantheum and Pseudanthus, each with two species. 
All four Tasmanian species are monoecious (i.e. with separate male and female flowers on the same plant).
Of the other genera previously included in Euphorbiaceae, Amperea, Bertya, Beyeria, Euphorbia, Ricinocarpus are retained in Euphorbiaceae, but  Phyllanthus and Poranthera are now included in Phyllanthaceae.
