“…Although Eriksen (1993a) indicated that the tribe Moutabeeae is polyphyletic, he and van der Meijden (1988) both accepted that the sister of Eriandra is Diclidanthera Mart., one of the American genera. Eriksen (1993b) accepted the Moutabeeae as previously defined and had it as sister to Xanthophyllum Roxb., diverse throughout Malesia.…”

Heads, Michael (Science Faculty, University of Goroka, PO Box 1078, Goroka, Papua New Guinea. Current address: Biology Department, University of the South Pacific, P.O. Box 1168 2003. Ericaceae in Malesia: vicariance biogeography, terrane tectonics and ecology. Telopea 10(1): 311-449. The Ericaceae are cosmopolitan but the main clades have well-marked centres of diversity and endemism in different parts of the world. Erica and its relatives, the heaths, are mainly in South Africa, while their sister group, Rhododendron and relatives, has centres of diversity in N Burma/SW China and New Guinea, giving an Indian Ocean affinity. The Vaccinioideae are largely Pacific-based, and epacrids are mainly in Australasia. The different centres, and trans-Indian, trans-Pacific and trans-Atlantic Ocean disjunctions all indicate origin by vicariance. The different main massings are reflected in the different distributions of the subfamilies within Malesia. With respect to plant architecture, in Rhododendron inflorescence bracts and leaves are very different. Erica and relatives with the 'ericoid' habit have similar leaves and bracts, and the individual plants may be homologous with inflorescences of Rhododendron. Furthermore, in the ericoids the 'inflorescence-plant' has also been largely sterilised, leaving shoots with mainly just bracts, and flowers restricted to distal parts of the shoot. The epacrids are also 'inflorescence-plants' with foliage comprised of 'bracts', but their sister group, the Vaccinioideae, have dimorphic foliage (leaves and bracts). In Malesian Ericaceae, the four large genera and the family as a whole have most species in the 1500-2000 m altitudinal belt, lower than is often thought and within the range of sweet potato cultivation. The same belt is also most diverse for ferns, birds-of-paradise and bowerbirds. Distribution maps of Malesian Ericaceae are presented, with related species indicated. Concentric patterns of distribution are frequent and could be attributable to evolution around shrinking seas. In New Guinea the main axial range is a composite structure, with the southern part formed by the old Australian craton and the northern and eastern parts formed from 32 tectonostratigraphic terranes or microplates. These formed independently and then docked with each other and the craton. The tectonic boundary between the craton and the accreted terranes is also an important biogeographic boundary. Many taxa have distributions linking different accreted terranes but are not on the craton. Movement and integration of island arcs and more substantial terranes has led to complex patterns of disjunction throughout Malesia, but there is an underlying parallel-arc structure, seen clearly in New Guinea. The tectonic provinces in Borneo are also reflected in the two main biogeographic tracks: Kuching--Kinabalu and Kutei Mts./Mt. Kemul-Kinabalu, the Lupar River boundary and the Meratus Mts. centre. The islands of the Riouw Pocket (Corner 1978a) are notably surrounded by many groups which are absent th...

“…Regional treatments and recent molecular and morphological analyses of inter-and intra-family phylogeny, conducted by Eriksen (1993aEriksen ( , 1993b, Persson (2001), Monro (2003) and Forest et al (2007), have questioned the classification of Polygalaceae and sectional treatment of Polygala presented by Chodat (1896). Although these authors were unable to provide a fully resolved phylogeny for all Polygalaceae, they were able to highlight issues requiring further research, such as polyphyly in several genera such as Bredemeyera and Polygala.…”

“…Although these authors were unable to provide a fully resolved phylogeny for all Polygalaceae, they were able to highlight issues requiring further research, such as polyphyly in several genera such as Bredemeyera and Polygala. Apparently, the polyphyletic nature of Polygala is not surprising because several infrageneric groups have previously been recognised as independent genera (Eriksen 1993b). Four new genera have been proposed for North American Polygala, on the basis of phylogenetic data indicating four morphologically diagnosable clades that are more closely related to other genera than they are to the type group of Polygala (Abbott 2011).…”

“…However, these characters are not exclusive to Leptaleae and could also apply to series Chloropterae subsection Deltoideae ( Table 2). Given that some aspects of Chodat's classification are not supported by recent phylogenetic analyses (Eriksen 1993a(Eriksen , 1993bPersson 2001;Monro 2003;Forest et al 2007) and can be too ambiguous to apply, an infrageneric classification is not provided. However, it is possible to speculate on putative natural groups within the Australian material.…”

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.

“…Divisões infragenéricas têm sido propostas para o gênero (Bennet 1874; Chodat 1893; Paiva 1998), apoiadas na morfologia das flores, frutos, sementes e até na presença de nectários extraflorais. Eriksen (1993) utilizou dados morfológicos e anatômicos para sugerir que Polygala lato senso é polifilético. Entretanto, ressaltou a necessidade de um estudo mais amplo para o gênero.…”

Neste trabalho apresenta-se o tratamento taxonômico do gênero Polygala L., como parte do projeto "Flora da Paraíba". Realizaram-se coletas e observações de campo para as identificações, descrições e ilustrações botânicas que foram efetuadas após estudos morfológicos, com o auxílio da bibliografia especializada, complementados pela análise de espécimes de herbários. O gênero Polygala está representado na Paraíba por 11 espécies: Polygala boliviensis A.W. Benn., P. cyparissias A. St.-Hil. & Moq., P. galioides Poir., P. glochidiata Kunth, P. leptocaulis Torr. & A. Gray, P. longicaulis Kunth, P. martiana A.W. Benn., P. paniculata L., P. sedoides A.W. Benn., P. spectabilis DC. e P. violacea Aubl. Com exceção de P. cyparissias, P. galioides, P. glochidiata, P. spectabilis e P. violacea, as demais espécies constituem novas referências para o Estado da Paraíba.
