Acacia Miscellany 11. Miscellaneous taxa of northern and eastern Australia of Acacia section Plurinerves (Leguminosae : Mimosoideae)
COWAN, R.S. AND MASLIN, B.R., Nuytsia10 (1) :
Two new species (A. kenneallyi Cowan & Maslin and A. manipularis Cowan & Maslin) and one new subspecies (A. retivenea F. Muell. subsp. clandestina Cowan & Maslin) are described. Acacia lanigera Cunn. is distinguished from A. venulosa Benth. and is viewed as comprising three varieties, var. lanigera, var. gracilipes Benth. and var. whanii (F. Muell. ex Benth.) Pescott (syn. A. whanii F. Muell. ex Benth.). In addition, lectotypes for several taxa are designated herein: A. subporosa var. linearis Benth. (the base name for A. cognata Domin), A. excelsa Benth., A. hemignosta F. Muell., A. lanigera Cunn., A. lanigera var. gracilipes Benth., A. leucophylla Lindley (= A. pendula Cunn. ex Don), A. praelongata F. Muell., A. subporosa F. Muell., and A. trinervata var. brevifolia. A note concerning the binomial A. sericata Cunn. ex Benth. is also included and discussions are presented concerning A. farinosa Lindley, A. latescens Benth. and A. trinervata Sieber ex DC.
Acacia Miscellany 12. Acacia myrtifolia (Leguminosae : Mimosoideae : section Phyllodineae) and its allies in Western Australia
Five new species and one new subspecies of Acacia from Western Australia are described, namely, A. clydonophora Maslin, A. disticha Maslin, A. durabilis Maslin, A. heterochroa Maslin (comprising subsp. heterochroa and subsp. robertii Maslin) and A. pygmaea Maslin. These taxa, together with four previously described species, A. celastrifolia Benth., A. myrtifolia, A. nervosa DC. and A. obovata Benth. comprise the informal "Acacia myrtifolia Group". A key to the species of this Group is presented. Brief notes on the variation in the Western Australian populations of A. myrtifolia are given. Acacia pawlikowskyana Ohlend. is treated as a synonym of A. myrtifolia (this name was formerly treated as a synonym of A. celastrifolia). Acacia acutifolia Maiden & Blakely is also regarded as conspecific with A. myrtifolia; it is likely that the type information published by Maiden and Blakely for this name was erroneous.
Alyxia tetanifolia (Apocynaceae), a new species from south west Australia
A new species endemic to the Austin Botanical district of the Eremaean Botanical Province of Western Australia, namely A. tetanifolia, is described, illustrated and mapped. A key to Western Australian species of Alyxia is provided.
Robert Brown, the typification of his new Acacia names in edition 2 of Aiton's 'Hortus kewensis'
MASLIN, B.R. AND COWAN, R.S., Nuytsia10 (1) :
Robert Brown published nine new species of Acacia in W.T. Aiton’s second edition of "Hortus Kewensis". In the past, typification of these species has presented problems for two main reasons. Firstly, there were uncertainties regarding the material on which they were based, i.e. Brown’s "wild" gatherings from Australia between 1801 and 1805, and/or from plants in cultivation in England. Secondly, it appears that there are no cultivated specimens extant which can be regarded as type material. There is, however, a collection by William McNab, a gardener at Kew, who made specimens of Brown’s Acacia species from cultivated plants at Kew between 1806 and 1809; this collection is curated by the National Herbarium at Dublin (DBN). The following Brown species names are here lectotypified on the basis of Brown’s "wild" material: A. alata, A. biflora, A. marginata (=A. myrtifolia), A. melanoxylon, A. pulchella and A. sulcata; a neotype for A. acicularis (=A. brownii) has been chosen from Brown’s "wild" collections while A. armata is neotypified on a cultivated plant in the William McNab collection at DBN. One species, A. ciliata (= A. browniana var.browniana), had been neotypified in a previous paper.
New and priority taxa in the genera Spyridium and Trymalium (Rhamnaceae) of Western Australia

Half of these taxa are presently included on the Priority Flora List. Other species of Spyridium and Trymalium on this conservation priority list are also illustrated and two new combinations are made, namely Spyridium majoranifolium (Fenzl) Rye and Spyridium polycephalum (Turcz.) Rye.
Two new species of Tetratheca (Tremandraceae), from the Coolgardie and Austin Botanical Districs, Western Australia

A key and a table of differences are provided to facilitate recognition of the two newly described species and the morphologically-similar species T. aphylla and T. halmaturina.
Acacia Miscellany 13. Taxonomy of some Western Australian phyllocladinous and aphyllodinous taxa (Leguminosae : Mimosoideae)
Descriptions are provided for eleven endemic Western Australian species of Acacia characterized by phyllodes which are either decurrent on the stems and forming prominent opposite wings, or which are reduced to scales or minute, horn-like projections. Seven new species and two new infraspecific taxa of Acacia are described, namely, A. aemula Maslin which comprises two subspecies, subsp. aemula and subsp. muricata Maslin (syn. A. tetragonocarpa var. scabra Benth.), A. alata var. tetrantha Maslin, A. applanata Maslin, A. bifaria Maslin, A. carens Maslin, A. cerastes Maslin, A. cummingiana Maslin and A. pterocaulon Maslin. The taxonomy of A. alata R. Br. Is briefly assessed and the species is now viewed as comprising four varieties, namely, var. alata, var. biglandulosa Benth., var. platyptera (Lindl.) Meisn. and var. tetrantha Maslin. A description is provided for A. volubilis F. Muell.; this species is possibly extinct and seems related to A. aemula. Acacia glaucoptera Benth., a close relative of A. bifaria, and A. willdenowiana H. Wendl. (based on A. diptera Lindl.), a closerelative of A. applanata, are lectotypified.
Acacia Miscellany 14. Taxonomy of some Western Australian 'Uninerves-Racemosae species (Leguminosae : Mimosoideae : section Phyllodineae)
Eight new species of Acacia section Phyllodineae from Western Australia are described, namely, A. anthochaera Maslin, A. brumalis Maslin, A. chamaeleon Maslin (syn: A. stowardii S. Moore non Maiden, and provisionally A. leiophylla var. microcephala Meissner), A. dorsenna Maslin, A. gelasina Maslin, A. scleroclada Maslin, A. subrigida Maslin and A. wilcoxii Maslin. Lectotypes are selected for A. stowardii S. Moore, A. harveyi Benth. and A. leptopetala Benth. The ten species included in the paper have racemose inflorescences and are referable to series Uninerves subseries Racemosae as defined by Bentham (1864)

RYE, B.L. AND TRUDGEN, M.E., Nuytsia10 (2) :
In preparation for an account in Volume 17 of the "Flora of Australia", new taxa (10 series, 29 species, 24 subspecies, 10 varieties) and a new infrageneric classification are presented. Twelve new combinations are made. A number of previously-published names are lecto- or neotypified. The work is based on classical taxonomic methods. The genus now consists of three subgenera, 24 series, 92 species and 36 infrageneric taxa. Keys to all taxa are given. The conservation status is given for each taxon treated; some are very restricted and two almost extinct in the wild.

Drosera kenneallyi (Droseraceae), a new tropical species of carnivorous plant from the Kimberley, northern Western Australia
A new species, Drosera kenneallyi (Droseraceae), is described from tropical northern Western Australia. The features that distinguish this taxon from its nearest relatives are presented, with growth adaptations and habitat preferences indicated.
Stylidium fimbriatum (Stylidaceae), a new tropical species of triggerplant from the Kimberley, Western Australia
LOWRIE, ALLEN AND KENNEALLY, KEVIN K., Nuytsia10 (3) :
Wurmbea saccata is described as new and illustrated with drawings and a photograph. It occurs in an apparently limited area of the remote Barlee Range Nature Reserve, south east of Onslow, Western Australia. The tepal nectaries are concealed in pouches formed by the lower part of each tepal and its adjacent staminal filament, a feature unique in the genus. The plants are commonly visited by unidentified day-flying lepidoptera. The new species is closely related to W. densiflora (Benth.) T.D. Macfarlane.
Eucalyptus semota (Myrtaceae), a new species from the Ashburton District of Western Australia
MACPHERSON, C.J. AND GRAYLING, P.M., Nuytsia10 (3) :
