Exocarpos (family Santalaceae) A genus of shrubs and small trees in which the leaves are reduced to small scales. The roots usually cling to other plants, on which they are semi-parasitic. The scale-like leaves are opposite or alternate. The flowers, held in short spikes or clusters in the leaf axils, are small and cream-coloured and have 4 or 5 perianth segments. The fruit is a nut with a fleshy stalk. There are 26 species, found in Southeast Asia, Australia, and New Zealand.
