often plumose in the female flowers. Fruit a small 2 to 4 or rarely 5-celled drupe 
or nut, the adnate calyx either smooth or variously ribbed, angled, winged, or 
muricate. — Herbs or undershrubs, glabrous, scabrous or hispid. Leaves alternate 
or opposite, entire toothed or lobed. Flowers small, solitary or several together in 
the axils of the floral leaves or bracts, forming leafy or leafless racemes, either 
simple or in a branching terminal panicle. Pedicels usually very short, with 2 
small opposite often deciduous bracteoles under the flower. 
The genus is chiefly Australian, but a few species are also found in New Zealand, in Eastern 
Asia, in S. Africa, and extratropical S. America. The characters derived from the ribs and 
wings of the fruit, upon which the genus had been divided into three, are either too little in 
accordance with other distinctions, or too variable in certain species, to be available even as 
sectional. Most of the species are monoecious, the female flowers variously mixed in with the 
males, and although I have frequently had specimens with the flowers all of one or the other 
kind, I have not been able to ascertain that any species is constantly dioecious. The males have 
never plumose stigmas, but I always find small obtuse styles and their corresponding ovules, 
which appear often to come to perfection. The females have usually smaller petals or none at 
all, fewer stamens or none or filiform filaments only. As the differences between the two are 
probably the same in nearly all the species, I have not alluded to them . in the specific 
characters. — Benth.
