“…Dipterocarpaceae are notably emphasized in biogeographic hypotheses for lineage movements from Africa or, more often, India into Southeast Asia (Ashton 1982, Morley 2003, Ghazoul 2016. Current biogeographic interpretations (Morley , 2018aHeckenhauer et al 2017) are based on the relationship of Sarcolaenaceae to Dipterocarpaceae, the timing of clade divergence within the family, and the relationships of fossils to crown lineages of Southeast Asian dipterocarps (Dipterocarpoideae). In addition to the relatively large-seeded, mostly wind-dispersed species in the Asian subfamily Dipterocarpoideae, the Dipterocarpaceae include the subfamilies Monotoideae, with species in Africa, Madagascar, and the Colombian Amazon, and the monospecific Pakaraimaeoideae, from the Guianan Highlands of South America (Heckenhauer et al 2017).…”

“…Recent interpretations based on molecular data (Ducousso et al 2004, Chase et al 2016, Heckenhauer et al 2017 have shown the Dipterocarpaceae to be paraphyletic. Pakaraimaeoideae resolve as sister to Cistaceae, and Sarcolaenaceae (endemic to Africa and Madagascar) are placed as sister to a pantropical clade composed of Monotoideae plus Dipterocarpoideae (Africa, Madagascar, South America, and Southeast Asia, in total).…”

“…The presence of Dipterocarpaceae in the African Paleogene macrofossil record also remains uncertain (e.g., Jacobs 2004, Jacobs et al 2010. Although Gondwanan origins of Dipterocarpaceae (Ashton 1982) are still frequently suggested (e.g., Ghazoul 2016, Heckenhauer et al 2017, no fossils of the group have been recorded from any part of Gondwana. The nearest example to Gondwana temporally is cf.…”

“…The oldest macrofossils with dipterocarp affinities are fossil twigs similar to Anisoptera from the early Eocene London Clay (Poole 1993), although, given their relative maturity, these should be considered unconfirmed because they lack some diagnostic characters exhibited by mature wood of the family (E. Wheeler, personal communication, 2019). Shoreoxylon woods from the middle Eocene Pondaung Formation of Myanmar (Licht et al 2014) (Heckenhauer et al 2017). The amber and the floral and faunal fossils of the Eocene-Oligocene Na Duong section in Vietnam (Böhme et al 2013) include reference to dipterocarps on the basis of amber composition but without supporting evidence from macrofossils.…”

Unraveling the origins of Malesia's once vast, hyperdiverse rainforests is a perennial challenge. Major contributions to rainforest assembly came from floristic elements carried on the Indian Plate and montane elementsfrom the Australian Plate (Sahul). The Sahul component is now understood to include substantial two-way exchanges with Sunda inclusive of lowland taxa. Evidence for the relative contributions of the great Asiatic floristic interchanges (GAFIs) with India and Sahul, respectively, to the flora of Malesia comes from contemporary lineage distributions, the fossil record, time-calibrated phylogenies, functional traits, and the spatial structure of genetic diversity. Functional-trait and biome conservatism are noted features of montane austral lineages from Sahul (e.g., diverse Podocarpaceae), whereas the abundance and diversity of lowland lineages, including Syzygium (Myrtaceae) and the Asian dipterocarps (Dipterocarpoideae), reflect a less well understood combination of dispersal, ecology, and adaptive radiations. Thus, Malesian rainforest assembly has been shaped by sharply contrasting evolutionary origins and biogeographic histories.

“…This monotypic genus is from the huge plant family Dipterocarpaceae. At present, there are uncertainties in the classification of Dipterocarpaceae, compromising the understanding of evolution within the family (Heckenhauer et al 2017) and hampering conservation efforts of its member species. Currently, there is no complete chloroplast (cp) genome sequence of any Dipterocarpaceae species available in the NCBI GenBank database.…”

Known for its durable timber quality, Neobalanocarpus heimii (King) Ashton is a highly sought after tree species endemic to the Malay Peninsula. Due to its scarcity and high value, the tree is classified under the IUCN Red List categories of Vulnerable. In this study, we assembled the complete chloroplast (cp) genome of N. heimii using data from high-throughput Illumina sequencing. The Chengal cp genome is 151,191 bp in size and includes two inverted repeat regions of 23,721 bp each, which is separated by a large single copy region of 83,801 bp and a small single copy region of 19,948 bp. A total of 130 genes were predicted, including 37 tRNA, 8 rRNA, and 85 protein-coding genes. Phylogenetic analysis placed N. heimii within the order Malvales.

Phylogenomics and a revised tribal classification of subfamily Dipterocarpoideae (Dipterocarpaceae)

Dipterocarpoideae, the largest subfamily in the Meranti family (Dipterocarpaceae) are an ecologically dominant group of trees throughout much of wet tropical Asia. Increasing anthropogenic pressures on this economically important tree family make it essential to resolve their complex evolutionary relationships and understand the distribution of genetic diversity throughout the family and distribution range. Dipterocarpaceae have been the focal group in a wide range of studies, owing to their economic value, importance in historical biogeography and key role in the evolution of the Asian tropical forest biome. Despite this, persistent taxonomic and evolutionary questions remain, ranging from questions on the geographic origin, sequence of dispersal and the identification of diagnostic characters to circumscribe proper evolutionary groups. Here we present a comprehensive phylogenomic hypothesis for Dipterocarpoideae, based on the analyses of plastome and nuclear cistron (NRC) data, and provide an in‐depth review on the validity of morphological characters underlying the new tribal classification proposed here for the subfamily. Phylogenomic relationships were inferred using maximum likelihood and Bayesian approaches. Estimates of origin and onset of diversification in major clades and lineages were reconstructed using plastome, nuclear and combined datasets. Results of the separate and combined genomic datasets partly corroborate elements of previous classification systems (with improved support at all levels for major clades) but provide strong support for revising the tribal classification of the subfamily into four main clades: Dipterocarpeae (Dipterocarpus), Dryobalanopseae (Dryobalanops), Shoreeae (Hopea, Neobalanocarpus, Parashorea, and all parts of a polyphyletic Shorea) and Vaterieae (including all other presently accepted Dipterocarpoideae genera). Multi‐fossil‐dated divergence time estimation suggests Vaterieae first originated in the Late Cretaceous, followed by Dipterocarpeae, with subsequent rise of the Dryobalanopseae and Shoreeae in the Eocene. Diversification of all tribes commenced before the Early Miocene. Our results provide strong support for the position of Neobalanocarpus heimii, Parashorea and (sub‐)sections of the genera Anisoptera, Hopea, Shorea and Vatica. Hypotheses on the origin of Neobalanocarpus heimii by intergeneric hybridisation between Anthoshorea (maternally inherited) and Hopea (paternally inherited) species were corroborated. Finally, our study provides support for future revisionary changes: (1) the elevation to generic rank of sections in Shorea; and (2) revising the infrageneric classification of Hopea as all (sub‐)sections were recovered as not monophyletic.
