“…The Areae comprise Arum with 29 species (Boyce, 1993(Boyce, , 2006Lobin & al., 2007), Biarum with 21 (Boyce, 2008), Dracunculus with 2 (Mayo & al., 1997), Eminium with 9 (Mayo & al., 1997;Bogner & Boyce, 2008), Helicodiceros with 1 (Mayo & al., 1997), Theriophonum with 5 (Sivadasan & Nicolson, 1982;Mayo & al., 1997), Typhonium s.l. with 72 species (Hay, 1993(Hay, , 1997Sriboonma & al., 1994;Hay & Taylor, 1996;Sookchaloem & Murata, 1997;Hetterscheid & Boyce, 2000;Hetterscheid & Nguyen, 2001;Murata & al., 2002;Wang & al., 2002;Hetterscheid & Galloway, 2006;Dao & al., 2007;Nguyen, 2008: this number includes species here shown to belong in Sauromatum or the Australian clade), and at least 14 as yet undescribed species belonging to various of these genera. For this study, we included 52 species of Typhonium s.l., 18 of Arum, 9 of Biarum, 2 each of Eminium and Theriophonum, both Dracunculus species, and the single species of Helicodiceros.…”

With in excess of 70 species, the Southeast Asian/Australian genus Typhonium is the largest genus of the Areae, a tribe that includes up to nine smaller genera of which Sauromatum and Lazarum have recently been reduced to the synonymy of Typhonium. To test the circumscription and relationships of Typhonium to the other Areae, we used chloroplast and nuclear DNA sequences (4319 aligned nucleotides) for 86 of the total 153 species, including representatives of all relevant genera. In the resulting phylogeny, Typhonium species fall into three well-supported clades: the first comprises most Typhonium species, including the type, T. trilobatum ; the second consists of the type of Sauromatum, S. guttatum, and other species formerly placed in that genus; the third includes only Australian endemics. Each of the remaining six genera of Areae is monophyletic. Sauromatum and Typhonium are not sister groups, requiring the recognition of Sauromatum. The Australian clade also needs to be ranked as a genus to achieve similar levels of morphological, geographic, and genetic distinctness among the genera of Areae. However, since only 10 of the 16 described Australian endemics currently placed in Typhonium have so far been sequenced, not including the type of the name of the Australian genus Lazarum, we refrain from applying this name to the Australian clade. Among the nomenclatural and taxonomic results of this study are a key to the nine species of Sauromatum, and five new combinations. We also report two new chromosome counts and discuss the implications of the molecular phylogeny for the evolution of Sauromatum karyotypes.

“…The first species we described, in collaboration with Alistair Hay from the Royal Botanic Gardens, Sydney, was Typhonium peltandroides A.Hay, M.D.Barrett & R.L. Barrett (Hay et al 1999). This species was found in a single gorge in the centre of Beverley Springs (Charnley River) Station; only recently has a second population been discovered, in Prince Regent National Park (R.L.…”

Barrett, R.L. Fifty new species of vascular plants from Western Australia-celebrating fifty years of the Western Australian Botanic Garden at Kings Park. Nuytsia 26: 3-20 (2015). This paper introduces a special issue of Nuytsia containing seven collaborative papers naming 50 new species of Western Australian vascular plants. It has been compiled to celebrate the 50 th anniversary of the opening of the Western Australian Botanic Garden at Kings Park. Several species are named after former Kings Park staff to honour their contributions to botany in Western Australia, including one that occurs naturally in the Kings Park bushland and is named after one of the designers of the Botanic Garden. Field research by Kings Park staff across Western Australia, including the rediscovery of Auranticarpa resinosa (Domin) L.W.Cayzer, Crisp & I.Telford, missing for 180 years, is documented.

“…A new species of Typhonium (Araceae: Areae) from the West Kimberley, Western Australia Typhonium Schott is a genus of about 40 species of East Asian and Australian geophytic, mostly saproentomophilous aroids, the largest genus of the eastern-hemispheric tribe Areae. Typhonium has been revised recently for Australia (Hay 1993) and in toto (Sriboonma 1994), with the subsequent addition of three new species in Australia (Hay 1996; Hay & T aylor 1 997). Several further new species are also coming to light in Indochina (Dzu & Croat 1997 ;Hetterscheid, pers.…”

“…The new species is clearly allied to T. alistnifolium F. Muell., a species which Hay (1993) treated provisionally as arather widely circumscribed complex in need of further resolution. Typhonium alismifolium has a wide distribution from north-eastern Queensland to Central Australia, and has recently been recorded, as a very robust variant, from near Oodnadatta, South Australia (Hay, in prep.).…”
