I.M. Turner’s research while affiliated with Singapore Botanic Gardens and other places

... Based on a dense worldwide sampling of Vitaceae, we constructed a robust dated phylogeny of the family and inferred its biogeographic diversification. Within this plant groups and biomes around the globe 1,2,4,[8][9][10] . However, recent studies have revealed that the evolve strategy is also important in plant response to changing environments through rapid evolution [11][12][13][14] . ...

... Since the work of Lindsay et al. (2022), additional rediscoveries and new records have been documented (e.g., Ng, Yong, & Lim, 2022;Niissalo et al., 2023;Thomas et al., 2023) and incorporated into the Singapore Red Data Book (third edition) to update the conservation statuses of all native plant species in Singapore (Middleton et al., in press). 1 We compared the statuses of vascular plant taxa (including infraspecific ranks) listed in Chong et al. (2009) with Lindsay et al. (2022 and Singapore Red Data Book (third edition; Middleton et al., in press). ...

... Additionally, due to the medicinal importance of B. repens, it will be registered as a new medicinal plant in Libya. Previous studies have highlighted the various medicinal properties of B. repens, including its use as a potent antioxidant (Rahman, 2014;Choo et al., 2022), a diuretic, and in the treatment of conditions such as jaundice, constipation, fever, blood purification, stomach-aches, yaws, gonorrhea, dropsy, asthma, scabies, skin rashes, smallpox, and viral infections (Muzila, 2006). The root of B. repens is also known to have purgative properties (Nazneen et al., 2016). ...

... In contrast, L. ferruginea is nationally endangered in Singapore, and occurs in scattered small clumps in the rainforest fragments within the island state (Lindsay et al., 2022;Loo et al., 2015). The fruits are drupaceous, crimson to pink in colour when immature and ripening dark purple to black, 15-17 by 12-15 mm when fresh, with a smooth surface. ...

... These two anther characters clearly can be differentiated. Whereas Nazre (2018) considered G. sumbawensis and G. sumbawaensis to be conspecific, the comparison above indicates that they are distinct, as Turner & Jennings (2021) argued. Indeed, they are treated as such in the Plants of the World Online (POWO, 2023). ...

... In general, phylogenetic information is greater in faster-evolving regions of the genome. A common result in target capture-based phylogenetics is that non-coding sequences-in the form of introns and intergenic regions-significantly improve resolution when incorporated into phylogenetic analyses (e.g., Folk et al. 2015;Jones et al. 2019;Bagley et al. 2020;Maurin et al. 2021; Thomas et al. 2021). This is not just because of an increase in the overall information content of the data, but also because having informative individual loci is crucial for accurate phylogeny inference in the presence of incomplete lineage sorting (ILS; Avise et al. 1987;Maddison 1997;Rosenberg 2006, 2009). ...

... These herbs, including Jussiaea linifolia Vahl of the Onagraceae family, are well distributed in tropical regions. Jussiaea linifolia (synonymous with Jussiaea hyssopifolia G. Don and Ludwigia hyssopifolia G. Don) Exell), also known as water primrose, is an herbaceous, aquatic, or marshy plant with diverse ethnomedicinal importance [3]. In traditional medicine, J. linifolia is used in the treatment of many parasitic infections [4]. ...

... Due to the old and highly weathered nature of many tropical soils, particularly Ultisols and Oxisols, soil aluminium concentrations are high, and thus aluminium hyperaccumulation has also evolved in a number of plant species. Among tropical species, aluminium accumulation is more common than accumulation of other metals and there are a number of studies with semi-quantitative analysis of a range of plant species from across the globe (Chenery, 1948;Jansen et al., 2000Jansen et al., , 2004Jansen, Watanabe, & Smets, 2002;Turner et al., 2021;Webb, 1954). The evolutionary reasons for metal hyperaccumulation have not yet been confirmed but many explanations focus on the potential defensive capabilities of having high metal concentrations in the leaves, the so-called "elemental defense" hypothesis (Boyd, 2007). ...

... Benjamin Heyne took more than 1500 specimens with him on his journey to Europe in 1812, which he had collected mainly in India and partly in Sumatra and intended to commission the well-known German botanist Carl Ludwig Willdenow to process the material (Turner, 2021). However, due to Willdenow's death in 1812, he chose Albrecht Wilhelm Roth to work on his collections (Turner, 2021). ...

... Pada studi sistematika tumbuhan, spesimen umum dapat berubah status menjadi spesimen tipe, apabila tumbuhan pada spesimen tersebut merupakan jenis baru yang telah dipertelakan sesuai aturan penamaan tumbuhan terkini (Turland et al., 2018). Spesimen herbarium diperlukan dalam kajian botani, seperti revisi taksa (Yu et al., 2021), pemutakhiran tata nama, analisis hubungan kekerabatan, studi keanekaragaman, studi evolusi eksaptasi (Heberling & Isaac, 2017), studi biogeografi dan perubahan lingkungan (Lavoie, 2013), penyusunan daftar jenis (Prunera-Olive et al., 2021), studi fenologi (Lima et al., 2021), studi endemis suatu flora (Véron et al., 2021), studi flora introduksi dan invasif (Damayanto & Muhaimin, 2017), studi biologi konservasi (Rocchetti et al., 2021), dan lain sebagainya. Dengan demikian, pengamatan spesimen herbarium merupakan kegiatan yang sangat penting dilakukan dalam mengkaji bidang botani. ...
