Of these taxa, 32 are new records for Australia (prefaced with a †). These species are: Abutilon pictum, Acanthus mollis, †Aesculus indica (naturalising), Agapanthus praecox subsp. orientalis, Ajuga reptans, †Anigozanthos flavidus, Aquilegia vulgaris, Arbutus unedo, †Athertonia diversifolia (naturalising), †Bergenia x schmidtii (naturalising), Bromus catharticus subsp. stamineus, Bryophyllum daigremontianum, Bryophyllum fedtschenkoi, Calyptocarpus vialis, †Ceiba speciosa (naturalising), Cereus uruguayanus, †Cestrum x cultum, †Chamaecyparis lawsoniana, Cistus salviifolius, †Clematis montana, †Coprosma x cunninghamii, Coprosma robusta, Cornus capitata, Cotoneaster simonsii, Cotoneaster x watereri group, Crinum moorei, Cupressus lusitanica, †Cylindropuntia fulgida var. mamillata forma monstrosa, †Cylindropuntia prolifera, Cylindropuntia tunicata, Desmanthus virgatus, Drosanthemum candens, †Elaeagnus umbellata (naturalising), †Eragrostis trichophora, †Eupatorium lindleyanum, †Gibasis pellucida, Glechoma hederacea, †Hesperis matronalis, Hieracium aurantiacum subsp. carpathicola, †Inga edulis (naturalising), †Juniperus conferta (naturalising), †Justicia caudata, Lamium galeobdolon, Lathyrus tingitanus, †Lysimachia fortunei, †Maackia amurensis, †Monstera deliciosa, †Murdannia keisak, Odontonema tubaeforme, Oxalis vallicola, Phoenix canariensis, †Physostegia virginiana, Pinus patula, Pittosporum eugenioides, †Pittosporum ralphii, Pittosporum tenuifolium, Plectranthus ecklonii, †Potentilla vesca, †Prunus campanulata, †Rhododendron ponticum, Rosa luciae, Rubus rugosus, Ruellia squarrosa, †Senna multijuga, Stapelia gigantea, Stephanophysum longifolium, Strobilanthes anisophylla, †Tabebuia chrysotricha, †Tabebuia impetiginosa, †Tradescantia pallida and Ulmus x hollandica. Additional notes and name changes are recorded for plants first recognised as naturalised for New South Wales over the period 2000–2001. The identification of several naturalised taxa occurring in New South Wales has been corrected. Plants formerly identified as Pinus nigra var. corsicana are now considered to be Pinus halepensis; Cylindropuntia arbuscula is Cylindropuntia kleiniae, Cylindropuntia tunicata is Cylindropuntia rosea, Abrus precatorius subp. precatorius is now Abrus precatorius subsp. africanus and Cotoneaster ?horizontalis is Cotoneaster microphyllus. Further field studies have revealed thatCylindropuntia leptocaulis, Cylindropuntia spinosior, Hypericum kouytchense and Chamaesyce ophthalmica are more widespread than previously thought.

Only taxa This paper is part of a series covering species recognised considered to be spreading from initial plantings or other as naturalised or naturalising by the National Herbarium of naturalisations (e.g. from discarded garden refuse) are New South Wales (standard code for this herbarium, NSW, covered. ‘Naturalised’ in this paper refers to non-native taxa is used throughout this paper). An earlier paper covered the that have been reproducing (sexually or vegetatively) in the period 2000–2001 (Hosking et al. 2003). This paper draws wild for at least one generation. ‘Naturalising’ covers taxa attention to a number of new naturalisations recorded for that are growing in the wild that have not yet reproduced, or the state of New South Wales (N.S.W.) and the Australian are not spreading vegetatively. 140 Cunninghamia 10(1): 2007 Hosking et al, Plant species recognised as naturalised for NSW 2002–2003 Methods professional botanists and staff from Landcare and Greening Australia, and (ii) specimens retained by herbaria who All taxa treated are represented by vouchers lodged at NSW provide plant identifications for the general public. or the Australian National Herbarium, Canberra (CANB). More species (71 species) were first recorded as naturalised A number of taxa listed were first collected prior to 2002 in N.S.W. during 2002 and 2003 compared with 40 for 2000 but are included here as these records were overlooked for and 2001 (see Hosking et al. 2003), mainly due to increased Flora of New South Wales accounts and were subsequently effort to record naturalised plants in the Blue Mountains near noted during 2002 or 2003.

In the long term, this approach will focus attention on potential problem species, and hopefully lead to The Germplasm Resources Information Network database their eradication before they have the opportunity to spread (USDA) (URL http://www.ars-grin.gov/cgi-bin/npgs/html/ and become serious weeds. taxgenform.pl) and the International Plant Name Index (http://www.us.ipni.org/index.html) were extensively consulted to determine currently accepted names, authorities Plant species first recognised as naturalised in New and native range of taxa covered in this paper.
