ABSTRACT Phylogenetic relationships among 122 species of Lauraceae representing 44 of the 55 currently recognized genera are inferred from sequence variation in the chloroplast and nuclear genomes. The trnL-trnF, trnT-trnL, psbA-trnH, and rpll6 regions of cpDNA, and the 5' end of 26S rDNA resolved major lineages, while the ITS/5.8S region of rDNA resolved a large terminal lade. The phylogenetic estimate is used to assess morphology-based views of relationships and, with a temporal dimension added, to reconstruct the biogeographic history of the family. Results suggest Lauraceae radiated when trans-Tethyean migration was relatively easy, and basal lineages are established on either Gondwanan or Laurasian terrains by the Late Cretaceous. Most genera with Gondwanan histories place in Cryptocaryeae, but a small group of South American genera, the Chlorocardium-Mezilauruls lade, represent a separate Gondwanan lineage. Caryodaphnopsis and Neocinnamomum may be the only extant representatives of the ancient Lauraceae flora documented in Midto Late Cretaceous Laurasian strata. Remaining genera place in a terminal Perseeae-Laureae lade that radiated in Early Eocene Laurasia. Therein, non-cupulate genera associate as the Persea group, and cupuliferous genera sort to Laureae of most classifications or Cinnamomeae sensu Kostermans. Laureae are Laurasian relicts in Asia. The Persea group and Cinnamomum group (of Cinnamomeae) show tropical amphi-Pacific disjunctions here credited to disruption of boreotropical ranges by Eocene-Oligocene climatic cooling. The Ocotea complex accommodates remaining Cinnamomeae and shows a trans-Atlantic disjunction possibly derived from a Madrean-Tethyan ancestral distribution. These findings support Laurasian ancestry for most extant Lauraceae, with their considerable neotropical representation primarily derived from Early Miocene radiation of the Ocotea complex upon reaching South America.

Dated historical biogeography of the temperate Loliinae (Poaceae, Pooideae) grasses in the northern and southern hemispheres

“…Our dating is in agreement with studies on some Macaronesian flora that have recently proposed an early origin of those angiosperm taxa (e. g. Lauraceae) (Chanderbah et al, 2001;Carine et al, 2004). The genetic similarity between the sister taxa F. donax and F. drymeja has been further corroborated by cytogenetic data (Dawe, 1989) and successful artificial crosses resulting in fertile oifspring (Borrill et al, 1977).…”

Comparative analysis of the complete chloroplast genomic sequence and chemical components of Cinnamomum micranthum and Cinnamomum kanehirae

“…Persea americana is closest to Machilus and Phoebe. Phylogenetic tree is in accordance with angiosperm phylogenic group classification (Chanderbali et al 2001;Bremer et al 2009;Renner, 2011;Song et al 2016). This phylogenetic tree is also consistent with APG III and provides the basic framework for studying Lauraceae phylogenetics (Bremer et al 2009) and also supports the relationship of C. micranthum cp genome being close to C. kanehirae in Cinnamomum.…”

Diversity and Lability of Floral Phyllotaxis in the Pluricarpellate Families of Core Laurales (Gomortegaceae, Atherospermataceae, Siparunaceae, Monimiaceae)

“…Siparunaceae are sister to Atherospermataceae plus Gomortegaceae (Renner 2004). Either Monimiaceae have an unsettled position as sister to Lauraceae (Renner 1999(Renner , 2004, sister to Hernandiaceae (Qiu et al 1999(Qiu et al , 2006, or sister to a clade comprising Hernandiaceae and Lauraceae (Doyle and Endress 2000;Chanderbali et al 2001;Hilu et al 2003) or the position of Hernandiaceae, Lauraceae, and Monimiaceae is unresolved (Renner and Chanderbali 2000;Soltis et al 2007). Monimiaceae are divided into two subfamilies, Monimioideae (Peumus, Palmeria, and Monimia) and Mollinedioideae (all other genera; Renner 2004), with Hortonia as the basalmost genus.…”
