%X Notothixos is a genus of eight species distributed from Ceylon, Lower Burma and the    Philippines southwards and eastwards through the Malesian region to Santa Cruz Islands    and south-eastern Australia. It is distinguished by a dense and conspicuous indumentum    of dendritic, stellately branched or peltate hairs or scales, and by lateral stems subtended    by two prophylls and two cataphylls. The basic inflorescence unit is a small cymose    cluster subtended by a pair of small bracts, and conflorescence evolution has involved    the aggregation of cymules, and development of indeterminate conflorescences from    determinate ones. The entire genus has not been revised previously; four names are    reduced to synonymy of others for the first time here. Notothixos curranii Merrill, N.    merguiensis Danser and N. spicatus Krause are conspecific with N. floccosus (Thw.)    Hook.f, and N. schlechteri Krause is conspecific with N. leiophyllus Schumann. New    chromosome numbers are reported for two species: N. incanus (n= 13) and N. subaureus    (n = 12). Evidence suggests that the genus originated in the Malesian region, and that    it has reached Papuasia and Australia as part of an intrusive element following Miocene    collision of the Australian and Sunda plates.
