Mollemans, F.H. Drummondita wilsonii, Philotheca langei and P. basistyla (Rutaceae), new species from southwest Western Australia. Nuytsia 9(1): 95-109 (1993). One new species of Drummondita and two new species of Philotheca are described. All three taxa are apparently rare, each restricted to limited geographic areas. Drummondita wilsonii is similar to D. erieoides, but has unequal calyx segments in common with D. miniata. Philotheca langei and P. basistyla both have affinities with Eriostemon falcatus which is currently presumed extinct. Similarities between D. wilsonii, D. erieoides and D. miniata, pollination mechanisms and flower colour variation in Drummondita, distribution and flowering time of the D. erieoides group (which includes D. miniata and D. wilsonii) and the evolutionary history of the Drummondita erieoides group, D. hassellii group and D. calida are discussed. Additional collections were subsequently made by the author and the following descriptions are based on this material.

The ecology of Rutaceae species remains poorly understood, a pattern typical across Australia, with a few notable exceptions. There have been no comprehensive demographic studies of members of the family in Sydney, and only limited attempts to examine aspects of the biology of the species in the family. In particular, the seed biology and ecology of the family and the impact of fire on species are poorly understood. This review poses a number of questions for research on members of the Rutaceae.
A contribution to the flora of the Meredith Range, north-western Tasmania
In a vegetation survey at the Meredith Range, northwestern Tasmania, we record 64 taxa of vascular plants, 54 bryophytes and 83 lichens. The dominant vegetation at the study site is buttongrass (Gymnoschoenus) moorland and the species recorded are essentially typical for this vegetation type. However, the flora has been severely affected by relatively recent fires. Significant species records for the area include two lichens: Baeomyces rufus (Huds.) Rebent., a widespread Northern Hemisphere species previously unrecorded for Australasia, and Cladia occulta Kantvilas sp. nov, described here as new to science.
A new species and new combination in Craspedia (Asteraceae) from Tasmania
Telopea, 2002
. A new species and new combination in Craspedia (Asteraceae) from Tasmania. Telopea 9(4): 813-820. Craspedia glabrata (Hook.f.) Rozefelds from subalpine communities in Tasmania is recognised as a distinct species. It is distinguishable from all mainland Australian and Tasmanian taxa by its small size, white florets and narrowly oblanceolate, pale green leaves. Craspedia preminghana Rozefelds is characterised by its white florets and broad oblanceolate-obovate, green leaves with multiseptate hairs and is known only from the type locality at Preminghana (Mount Cameron West) in northwestern Tasmania. The distribution and conservation status of both species are examined.
. Uniquely Tasmanian -a review of the phylogenetic and biogeographical relationships of Tasmania's endemic vascular plant genera. Kanunnah 2: 35-86. ISSN 1832-536X. The endemic genera of Tasmania are a heterogenous assemblage of taxa, which are represented in families including Asteliaceae, Asteraceae, Campynemataceae, Cunoniaceae, Cupressaceae, Ericaceae, Haloragaceae sensu lato (including Tetracarpaea), Iridaceae, Malvaceae, Podocarpaceae, Proteaceae and Res tionaceae. Two informal groupings of genera are recognised, one group consists of old relictual genera (palaeoendemics) and a second group are relatively recent segregates (neoendemics). Palaeoendemics include the conifers, Athrotaxis, Diselma, Lagarostrobos and Microcachrys, and the flowering plants, Agastachys, Anodopetalum, Bellendena,

Asterolasia beckersii (Rutaceae), a new species from the Northern Tablelands, New South Wales
Telopea
Asterolasia beckersii Orme & Duretto (Rutaceae) is newly described. The species is restricted to the Nundle area (Tamworth district) on the Northern Tablelands of New South Wales. The species is related to A. correifolia (A.Juss.) Benth. and A. hexapetala (A.Juss.) Druce and can be distinguished from these by leaf, inflorescence and floral characters. The ecology and conservation status of A. beckersii are discussed and a key to Asterolasia for eastern Australia is provided. Orme and Duretto Conservation status: In 2004, this species was determined to be Endangered under Schedule 1 of the New South Wales Threatened Species Conservation Act 1995; it is not listed under Federal legislation. Plants are known to occur in Tuggolo Creek and Back River Nature Reserves, Tuggolo State Forest and the area above Dungowan Dam which is managed by local government and under some protection as a water catchment area (Fig. 1). After visits to each of the three sites, the extent of each population was found to be small, and where population size data was recorded with herbarium specimens, it was noted to be between one and 20 individuals. Etymology: The epithet honours Doug Beckers (NSW National Parks and Wildlife officer) for discovering the species. Key to the species and subspecies of Asterolasia found in eastern Australia (SA, Vic., NSW, Qld) Note: Of the taxa found in eastern Australia only A. asteriscophora subsp. albiflora (E Vic.; couplet 6), A. muricata (SA; couplet 1), A. phebalioides (SA, W Vic.; couplet 13) do not occur in NSW. All Western Australian species have 1-4 carpels and a key to these species is provided by Wilson (2013). The couplets leading to the subspecies of A. trymalioides are based on the key of McDougall et al. (2016).

Correa lawrenceana Hook. is a widespread species in south-eastern Australia with eight recognised varieties. The Tasmanian variety, var. lawrenceana, is morphologically diverse. The present study uses multivariate morphometrics, including cluster, ordination and canonical discriminant analyses of samples of all recognised varieties of C. lawrenceana to assess whether more than one Tasmanian form warrants taxonomic recognition. These analyses showed that (1) var. lawrenceana can be divided into two well discriminated groups that are both endemic to Tasmania, a glabrescent form from the north-east and a hirsute form from the western, central and south-eastern regions, (2) the glabrescent form matches the type of C. lawrenceana and thus retains the name var. lawrenceana, and the hirsute form matches the type of C. lawrenceana var. ferruginea Hook.f. that is reinstated. The two varieties are separated geographically except in a small area around Deloraine in the north where intermediate morphological forms occur. The density of trichomes on the abaxial leaf surface is important for distinguishing the two Tasmanian varieties. An updated key to all varieties of C. lawrenceana along with descriptions of the Tasmanian varieties is presented. Nomenclature of the Tasmanian taxa is discussed and C. lawrenceana, C. lawrenceana var. glabra Benth., C. lawrenceana var. glabra L.Rodway and C. ferruginea Gunn ex Hook. are lectotypified.
