Diospyros phengklaii (Ebenaceae), a new species from south-western Thailand

Abstract

The herbarium specimens of Diospyros (including type specimens, or digital images) conserved at BK, BKF, K, L, and P were studied.

Diospyros phuwuaensis (Ebenaceae), a new species from North-Eastern Thailand

“…Collections were made, processed, deposited in BK, BKF, K and SING, and compared to herbarium specimens of Diospyros (including type specimens and digital images) at BK, BKF, BM, E, K, L and P (herbarium acronyms according to Index Herbariorum, Thiers, continuously updated). Material of the new species was also compared to descriptions in the relevant literature (Hiern, 1873;Bakhuizen van den Brink, 1936-1955Ng, 1978;Phengklai, 1981;Lee et al, 1996;Singh, 2005;Huang et al, 2015;Udayan et al, 2015;Duangjai et al, 2018). The description below is based on both herbarium specimens and on field surveys during the period 2007-2019.…”

“…To clarify the taxonomic status and phylogenetic placement of the new species, we conducted phylogenetic analyses of the genus Diospyros and three other closely related genera in the family Ebenaceae based on sequence data of eight plastid regions (rbcL, atpB, matK, ndhF, trnK intron, trnL intron, trnL-trnF spacer, and trnS-trnG spacer). In total, 16 accessions representing 15 species are added to the already published data sets (Duangjai et al, 2018). These are new sequence data from two accessions of the new species and one of Diospyros kurzii, along with thirteen other Diospyros species which have genome sequence data available on GenBank, namely…”

“…(Ng, 2001). Three more new species have been described after that (Phengklai, 2005;Duangjai et al, 2018).…”

<p><strong>Flora of Nam Kading National Protected Area VII: a new species of <em>Diospyros</em></strong><em> </em><strong>(Ebenaceae)</strong><em>, <strong>D. laoensis</strong></em></p>

“…1), we collected an unknown species of Diospyros. Further studies based on specimens and literature of related species (Phengklai 1981(Phengklai , 2005Li et al 1996;Hô 1999;Ng, 2002;Gardner et al 2015;Duangjai et al 2018) showed that this taxon was morphologically distinct from previously known taxa. Here, we describe this new species as Diospyros laoensis Tagane & Soulad., and provide illustrations, a vernacular name and preliminary conservation assessment.…”

“…The genus Diospyros (Ebenaceae), with over 600 species, is widely distributed in Asia, Africa, the Americas, Australia and the South Pacific Islands, in mostly tropical and subtropical regions (Wallnöfer 2001;Duangjai et al 2006Duangjai et al , 2009Duangjai et al , 2018. In tropical Asia, species of Diospyros are found from coastal sandy or rocky shores up to lower montane mossy forests, including limestone hills and peat swamps, and are ecologically important components in the forests (Ng, 2002).…”
