Infrafamilial classifications and characters in Araliaceae: Insights from the phylogenetic analysis of nuclear (ITS) and plastid (trnL-trnF) sequence data

SEM investigation of pollen from the lower Eocene (Carinthia and Salzburg in Austria and Brixton, London area, in England): new findings of Vitaceae, Euphorbiaceae, Phyllanthaceae, Fabaceae, Anacardiaceae, Araliaceae and Apiaceae

“…Makino ex Hara in Miyoshi et al (2011 plate 186 Figs. 1-4) that belongs to the Asian palmate group of Araliaceae (Plunkett et al 2004) resemble our fossil pollen type. However, we refrain from further assignment because we have too little pollen material.…”

“…The ivy family, which is thought to have its roots in Gondwana, is today a medium-sized family that is mostly distributed in the subtropics and tropics, although some taxa also thrive under temperate conditions (Plunkett et al 2004;Wen et al 2001). The three pollen types affiliated to genera of the ''Aralia-Panax complex'' of Wen (2001): Aralia L. (two in the Krappfeld, EECO) and Panax L. (Brixton, PETM) have modern equivalents that today prefer more temperate climate conditions, whilst the indet.…”

Estudo Palinotaxonômico De Espécies De Schefflera (Araliaceae) Da Região Sudeste Do Brasil

“…Por outro lado, a variabilidade polínica verificada por Tseng & Shoup (1978) em Schefflera pode fornecer informações taxonômicas consistentes para a proposição de uma circunscrição mais precisa para o gênero, já que o mesmo constitui um grupo polifilético Plunkett et al 2004Plunkett et al , 2005Wen et al 2001 Tseng & Shoup (1978), a que mais se assemelha às espécies aqui analisadas é S. decaphylla (Seem.)

Ironplant (Astrotricha hamptonii, Araliaceae): an enigmatic species with a rich history in bioprospecting

“…Only A. hamptonii is known outside of this range, endemic to the Pilbara and Gascoyne regions of Western Australia, a disjunction of almost 2,000 km from all other species. Relatively little data are available on the phylogenetic relationships within Astrotricha (Plunkett et al 2004), but based on fruit morphology, Astrotricha hamptonii appears to show an affinity with a group of species characterised by fruit with well developed marginal wings (A. pterocarpa Benth., A. cordata A.R.Bean and A. intermedia A.R.Bean) from northern New South Wales and far north Queensland. The Pilbara region, and in particular the Hamersley Range geological block, is known to be an area of ancient endemism with a relatively large number of early-diverging and relictual lineages surviving there (Pepper et al 2008, McKenzie et al 2009).…”

“…is endemic to Australia, and appears to be among the earliest diverging lineages in core Araliaceae (Wen et al 2001, Plunkett et al 2004, Li and Wen 2014. Li and Wen (2014), using a combination of plastid and internal transcribed spacer data, arrived at an estimated divergence date for Astrotricha of around 90 MYa.…”
