The Australasian genus Chionochloa Zotov is revised for New Zealand; all 22 species are endemic including the one species on the subantarctic islands. One new species, ten new subspecies, one new variety, and one new form are described; C. pungens of Stewart L is submerged in C. crassiuscula; C. Xelata is given the status of a hybrid. Natural hybrids are reported, and 35 interspecifir combinations ate described.

There lire three major tussock Itrassland communities in the MJckenzie Country:(i) fescue·tuss(l(k ItrasslJnd where FIS/llra lIo,'ae·ze/a'ldide is abundJnt, (ii) red. tunock grassland where Chiolloch/oa rllbra is the physiognomic dominant, and (iii) ,nnw.tussock grassland where Chio/lo,.h/od riRida is the rhysill~nllmic (Iuminant.

SummaryAll valid names in Cortaderia Stapf (nom. cons.) are typified and recent treatments of the genus are substantially upheld. Taxa in Section Cortaderia are more precisely defined with no major nomenclatural changes except that C. jubata (Lem.) Stapf is regarded as the valid name for plants formerly known as “C. quila (Nees) Stapf”. In Section Bifida, C. aristata and C. trianae are regarded as synonyms of C. bifida, and C. sodiroana as synonymous with C. nitida; C. minima is regarded as a synonym of C. pilosa. The new combination C. archboldii (Hitchcock) Connor and Edgar is based on Danthonia archboldii from New Guinea. The genus is gynodioecious though in some species of Section Cortaderia only female plants are found.
