WILSON, PAUL G., Nuytsia 8 (2): 245–248 (1992)
A new species of Philotheca, that comes from the Austin Botanical District of Western Australia, is described and illustrated. Its relationship to other species of Philotheca and of Eriostemon sect. Nigrostipulae is discussed.

CHAPMAN, A.R. AND MASLIN, B.R., Nuytsia 8 (2): 249–283 (1992)
A key is presented to the thirteen taxa comprising the A. bivenosa group. Three new species, viz. A. didyma, A. startii and A. telmica, and one new subspecies, A. sclerosperma subsp. glaucescens, are described. Descriptions are provided for six previously published species, namely A. bivenosa DC., A. ligulata A. Cunn. ex Benth., A. rostellifera Benth., A. sclerosperma F. Muell., A. tysonii Luehm. and A. xanthina Benth. Acacia cupularis is reinstated. All species, except A. ampliceps Maslin and A. salicina Lindl., are illustrated.
Acacia Miscellany 6. Review of Acacia victoriae and related species (Leguminosae : Mimosoideae: section Phyllodineae)
MASLIN, B.R., Nuytsia 8 (2): 285–309 (1992)
A key is presented to the 10 species comprising the informal “Acacia victoriae group”. Five of these species, all from Western Australia, are described as new, namely, A. alexandri, A. aphanoclada, A. chartacea, A. ryaniana and A. synchronicia. Acacia glaucocaesia Domin (syn. A. glabripes Maiden & Blakely, non Domin) is reinstated but may ultimately prove better placed as an infraspecific taxon under A. victoriae Benth. Legumes are described for A. pickardii Tind. and a full description is given for A. dempsteri F. Muell. All species of the group are illustrated.
