Council of Heads of Australasian Herbaria (CHAH) is an association of the leaders of herbaria in Australia and New Zealand.
[2][3] It endorses the taxonomy and nomenclature of the Australian Plant Census,[4] which is the source for accepted names of species and, in particular, for accepted names of Australasian species.
It supports the Australian Plant Name Index.
[1] Membership of CHAH consists of the heads of the following herbaria: There are a further two council members: one to represent the constituent collections of the National Collection of Fungi; and another to represent Australian university herbaria.
[2] The council also invites observers to participate.
