Description

Mainly shrubs, has alternate leaves, which are crenate (wavy toothed) and serrate (saw toothed). They are densely arachnoid (have appearance of cobwebs) below, so much that they look white underneath. They are dioecious (producing male or female gametes), the flowers are monoecious (having separate staminate and carpellate flowers which are always found on the same plant), in small axillary androgynous cymules, minute bracts, ovate, scarious (Dry and membranous). The male flowers have perianths which are partite (divided to or nearly to the base), the 5 segments are valvate, ovate and have 5 stamens, with a rudimentary ovary. The female flowers have a perianth which is broadly cupular, persistent and adinate at the base of the ovoid and very oblique (slanting) ovary. The stigma is sub-apical (near tip), sessile (flowers growing straight from the stem) and discoid (resembling a disc or plate). The fruit (or seed capsule) maybe drupaceous (having a fleshy-like outer part), small and very oblique.

Habitat

They are found on the mountains of western New Guinea.
