A treatment for Polygala of northern Australia

Abstract

Abstract.A taxonomic treatment is presented for all Polygala L. species of northern Australia (north of 26 S). In total, 45 species are treated, of which 44 are native and 36 are endemic to Australia. Twenty-six new species and four new varieties are described. A key to all 50 Australian species is provided, including six introduced species (five of which are restricted to southern states of Australia and are not treated here in detail). Lectotypes are here designated for five names. Nomenclatural issues regarding P. linariifolia Willd., P. glaucoides L. and P. triflora L. are discussed.

Polygala idukkiana (Polygalaceae), a new species from the southern Western Ghats, India

“…Floral details were studied using stemi 508 stereo microscope equipped with axiocam 105 color camera (Zeiss, Germany). The description was prepared by examining all available specimens and the terminologies followed Simpson (2006), Kerrigan (2008Kerrigan ( , 2012, and Pastore (2018aPastore ( , 2018b. Herbarium sheets were prepared by conventional methods (Bridson & Forman 1991).…”

“…The genus is widely distributed throughout the world except in the Arctic, Antarctic, and New Zealand (Paiva 1998). The main centres of diversity are known from South Africa and the Americas (Kerrigan 2012). Pastore & al.…”

“…Chandrabose & Nair (1981) reported 15 species from South India while 27 species were reported in India by Banerjee (1993). Kerrigan (2008Kerrigan ( , 2012 in a treatment of Polygala from northern Australia, recognized 45 species, of which 26 species and four varieties were newly described. A key for the identification of all the 50 species found in Australia were also provided in this work.…”

“…After careful comparison of morphological characters in living and herbarium specimens (CALI), and after consulting relevant literature (Adema 1966;Chandrabose & Nair 1981;Banerjee 1993;Banerjee & Balakrishnan 2005;Chen & al. 2008;Ranjan 2009;Kerrigan 2008Kerrigan , 2012Yang & Chen 2013;Dönmez & Aydin 2018;Pastore 2018aPastore , 2018bSarvi & al. 2020;Ying 2020;Pastore & al.…”

A baker’s dozen of new wattles highlights significant Acacia (Fabaceae: Mimosoideae) diversity and endemism in the north-west Kimberley region of Western Australia

“…As a result of these and other surveys numerous undescribed plant species have been discovered in recent years, many of them relatively short-range or north Kimberley endemics. Examples include Acacia barrettiorum Lewington & Maslin, A. spectra Lewington & Maslin and A. willingii Lewington & Maslin (Lewington & Maslin 2009), and species from Boronia (Duretto 1997;, Backhousia (Harrington et al 2012), Bossiaea (Ross 2006), Byblis (Lowrie & Conran 1998;2007), Calytrix (Barrett et al 2009), Corymbia (Hill & Johnson 1995;Barrett 2007), Drosera (Lowrie 1996), Euphorbia (Halford & Harris 2012), Goodenia (Sage 2001), Grevillea (Kenneally 1988;Olde & Marriott 1993;Makinson 2000), Ipomoea (Johnson 2012), Micraira , Mitrasacme (Dunlop 1996), Planchonia (Barrett 2006), Polygala (Kerrigan 2012), Solanum (Barrett 2013), Stylidium (Lowrie & Kenneally 1996, 1997Kenneally et al 2013), Triodia Barrett & Barrett 2011) and Typhonium (Hay et al 1999), with many other novel taxa in preparation.…”
