A new species of Eucalyptus from the margins of salt lakes in Western Australia
CARR, S.G.M AND CARR, D.J., Nuytsia3 (2): 173–178 (1980)
A new species (Eucalyptus halophila) is described. It is included in the informal series "Bisectae" but appears to have no close affinity with any other species. It is characterized by persistent spiral phyllotaxis and stomata with anterior chambers occluded by cutinised polar wall ingrowths.
A new species and a new combination in Darwinia (Myrtaceae) from Western Australia
MARCHANT, N.G. AND KEIGHERY, G.J., Nuytsia3 (2): 179–182 (1980)
Darwinia wittwerorum sp. novo is described and illustrated and a new combination, Darwinia oxylepis (Turcz.) comb. novo is made. Both species occur in the Stirling Range National Park, south western Australia.
Thryptomene and Micromyrtus (Myrtaceae) in Central Australia - new species and notes
Seven species of Thryptomene and eight of Micromyrtus from arid and semi-arid regions of inland Australia are described and illustrated. Notes on the species and maps of their distribution are given and keys to their identity provided. Six are described as new (T. naviculata, T. wittweri, T. nealensis, M. barbata, M. fimbrisepala and M. serrulata) and new combinations (M. helmsii and M. stenocalyx) are made for two others.
A new species of Urocarpus (Rutaceae) from Western Australia
A new species of Urocarpus Drumm. ex Harv. (Rutaceae) is described from near Bindoon, Western Australia. It differs from U. grandiflorus (Hook.) P. G. Wilson in having narrowly oblong leaves and smaller flowers which are white in colour. In carpel number it provides a link between Urocarpus s.str. and Asterolasia F. Muell., supporting the suggestion that the latter genus should not be maintained.
