“…2 in Li et al 2004). The sister relationship between Parasassafras and Sinosassafras was supported by the matK data, but not by the combined ITS and matK data in Li et al (2004). The close relationship between Sassafras tzumu and S. randaiense is well supported by the combined chloroplast and the nuclear DNA sequences in our study.…”

“…The PCR amplification of chloroplast sequences was conducted following that of Chanderbali et al (2001) for rpl16, psbA-trnH, and trnL-F regions. Because of the difficulties in amplifying the ITS regions of Sassafras with the primers (LAUR 1 and ITS B) as used in Chanderbali et al (2001) and Li et al (2004), we designed a new reverse primer (LAUR 2: 5¢-CGCCTGACCTGGGGT -3¢).…”

Abstract. Sassafras (Lauraceae) consists of three species disjunct between eastern Asia (S. tzumu and S. randaiense) and eastern North America (S. albidum). Phylogenetic analysis based on sequences of nuclear ribosomal ITS and three chloroplast noncoding regions (rpl16, trnL-F, and psbA-trnH) showed that Sassafras is monophyletic and that the eastern North American S. albidum is sister to the clade of its two eastern Asian counterparts. Their intercontinental divergence was estimated to be 13.80 ± 2.29)16.69 ± 2.52 million years ago (mya) using the penalized likelihood method with the ITS and three chloroplast markers. Biogeographic analyses combined with fossil evidence suggest that Sassafras has a relict distribution in the Northern Hemisphere without a Gondwanan link. The divergence time of the two eastern Asian species (the continental Chinese Sassafras tzumu and S. randaiense endemic to Taiwan) is estimated to be 0.61 ± 0.75)2.23 ± 0.76 mya. Sassafras randaiense from Taiwan was most likely derived from an ancestor from continental China.

“…The Litsea complex pertains in suborder Laureae in Lauraceae family, and the taxonomic classification is referring to the natural close morphological characteristics and also analysis of DNA sequences. This taxon comprises 10 genera represented by pertaining in 500-700 species throughout the world [2]. The Litsea complex consists of three genera (Lindera, Litsea and Neolitsea) with 71 species in Peninsular Malaysia [1].…”

Abstract.A study was conducted at 13 locations of different forest types in Peninsular Malaysia to examine the association between Litsea complex (Lauraceae) and its soil properties. A total of 37 species and 786 individuals were recorded. Soil samples in each study plot were taken and Canonical Correspondence Analysis (CCA) was employed to determine relationships between species of Litsea complex and the edaphic features. This study showed that Machinchang Forest Reserve, Kedah was strongly associated with sand texture while Taman Negara, Pahang was influenced by silt. In other study sites, Bukit Fraser, Pahang was highly influenced by magnesium (Mg); Taman Negara, Pahang was influenced by nitrate nitrogen (NO 3 -N); and Gunung Belumut, Johor was influenced by elements of sodium (Na + ) and ammonium nitrogen (NH 4 -N). The species distribution shows that Litsea artocarpifolia, Litsea maingayi and Neolitsea villosa were closely related to silt, while Litsea tomentosa and Litseae rectinervia were associated with clay, and Litsea grandis was related to sand. For tenden cyon soil chemical characteristic, Litsea artocarpifolia, Litsea maingayi and Neolitsea villosa were strongly related to nitrate nitrogen (NO 3 -N) while Litsea tomentosa and Litsea erectinervia were related to potassium (K + ). On the other hand, Litsea myristicaefolia was influenced by cation exchange capacity (CEC) and Litsea johorensis was influenced by sodium (Na + ). This study indicates that the species distribution of Litsea complex at the different forest types was associated with various soil properties.

“…Various morphological and anatomical characters (Miquel 1858, Bentham 1880, Hooker 1886, Pax 1889, Kostermans 1957, 1968, 1973a, b, Hutchinson 1964, Rohwer 1993, Christophel et. al 1996, Van der Werff & Richter 1996, Van der Werff 2001 as well as selected molecular markers (Rohwer 2000, Chanderbali et al 2001, Li et al 2004) have been used to classify and re-classify the genera. As a result, several genera have repeatedly been recognised as distinct or reduced to the synonymy of other genera and placed under similar or different suprageneric groups and/or subgroups within Lauraceae.…”
