The informal “Pedunculata” group of Hakea consists of four species from northern Australia, H. arborescens R. Br., H. pedunculata F. Muell., H. persiehana F. Muell. and H. stenophylla A. Cunn. ex R. Br. A key to the species is provided together with a discussion of relationships within the group. Each species is typified and a new subspecies, H. stenophylla subsp. notialis R.M. Barker, is described from Western Australia.
A trial key and notes on Tribulus (Zygophyllaceae) in Australia, including one new species and validation of Tribulus suberosus
A taxonomic review of the Stylidium caricifolium Lindl. complex (Stylidiaceae) is presented. Six species are recognized, including the new taxa, S. maritimum, S. sejunctum and S.wilroyense Lowrie, Coates & Kenneally. Additionally, S. affine Sond. and S. nungarinense S. Moore are restored to species rank. Recognition of these species is supported by chromosome, allozyme, ecological, geographical and morphological evidence. All six taxa are endemic to south-west Western Australia.
A taxonomic revision of the genus Byblis (Byblidaceae) in northern Australia
LOWRIE, A. AND CONRAN, J.G., Nuytsia12 (1) :
The northern Australian species of Byblis (Byblidaceae) are revised and illustrated. Two new species, Byblis aquatica Lowrie & Conran and B. rorida Lowrie & Conran are named. Byblis liniflora subsp. occidentalis Conran & Lowrie is reduced to a synonym of B. filifolia Planch., which is reinstated as a distinct species. Lectotypifications are provided for B. filifolia and B. liniflora Salisb. A key, table and distribution maps for the four Byblis taxa in northern Australia are also presented.
Three new species of triggerplant (Stylidium: Stylidiaceae) from south-west Western Australia
LOWRIE, A. AND KENNEALLY, K.F., Nuytsia12 (1) :
Three new Stylidium species (Stylidiaceae) from south-western Australia, S. daphne, S. ireneae and S. paulineae Lowrie & Kenneally, are described and illustrated. The location for the holotype sheet of Stylidium coatesianum Lowrie & Carlquist is corrected.

Wilson, D. eneabbensis, D. geraldtonensis, D. graniticola, D. leemaniana, D. mollis and D. obovata . One new combination is made: D. velutina (Paul G. Wilson) Paul G. Wilson. A key to species is provided.
New names and new taxa in the genus Boronia (Rutaceae) from Western Australia, with notes on seed characters
As a precursor to the treatment for the "Flora of Australia" of Western Australian species of Boronia (Rutaceae), the following seven species and eight varieties or subspecies are described as new: B. acanthoclada, B. anceps, B. baeckeacea subsp. patula, B. baeckeacea subsp. rosea, B. corynophylla, B. crenulata var. angustifolia, B. crenulata subsp. obtusa, B. exilis, B. humifusa, B. juncea subsp. minima, B. purdieana subsp. calcicola, B. ramosa subsp. lesueurana, B. scabra subsp. attenuata, B. scabra subsp condensata, B. tetragona, and B. westringioides. The following new subspecific combinations are made: B. crenulata subsp. pubescens (Benth.) Paul G. Wilson, B. crenulata subsp. viminea (Lindl.) Paul G. Wilson, B. fastigiata subsp. tenuior (Benth.) Paul G. Wilson, B. juncea subsp. laniflora (Bartl.) Paul G. Wilson, B. juncea subsp. micrantha (Bartl.) Paul G. Wilson. Lectotypes have been designated for a number of species.

Illecebrum verticillatum (Caryophyllaceae), a new record for Australia
In October 1996 a small alien herb, Illecebrum verticillatum L., was found on Big Rock, near Dunsborough, Western Australia. It was collected by Ralf Ohlemueller (Ohlemueller 252), a visiting botanist from Munich, who was studying the plants occurring on granite outcrops in this State.
