“…Molecular phylogenetic analyses have proven useful in resolving relationships at the generic level in Melastomataceae (Ionta et al, 2007;Reginato et al, 2010;Stone & Andreasen, 2010;Stone, 2014;Kriebel, 2016;Reginato & Michelangeli, 2016;Veranso-Libalah et al, 2017). Several phylogenetic studies had included Phyllagathis or Phyllagathis and Bredia in their analyses (Clausing et al, 2000;Clausing & Renner, 2001b;Fritsch et al, 2004;Zeng et al, 2016aZeng et al, , 2016bZhou et al, 2018). The most recent analyses revealed that both Phyllagathis and Bredia were not monophyletic, showing close relationships with Allomorphia Blume, Blastus Lour., Fordiophyton Stapf, Oxyspora DC., Plagiopetalum Rehder, Sonerila Roxb., and Tigridiopalma (Zeng et al, 2016a(Zeng et al, , 2016bZhou et al, 2018).…”

Phyllagathis Blume and Bredia Blume (Sonerileae s.l., Melastomataceae) are two closely related Asian genera with similar morphology and overlapping geographical range. Their generic circumscription and phylogenetic relationships are far from fully understood. We present here a molecular phylogenetic investigation for the two genera using nuclear ribosomal internal transcribed spacer and chloroplast (trnV‐trnM) sequence data. Seventeen genera of Sonerileae s.l. were included in the analyses, with Phyllagathis and Bredia densely sampled to cover their geographical range and morphological diversity. We identified 14 well supported species clusters within Sonerileae s.l.–Medinilla. Phylogenetic analyses together with reconstruction of morphological characters clearly indicated the taxonomic mess in generic delimitation of Sonerileae s.l. Many of the characters traditionally used in generic delimitation were highly homoplasious. Bredia and Phyllagathis, as well as Allomorphia, Anerincleistus, Fordiophyton, and Oxyspora, were revealed to be non‐monophyletic. Bredia, as currently defined, contains two groups of species with different phylogenetic affiliations. Bredia should be recircumscribed to exclude the Bredia–Phyllagathis clade I and accommodate the Bredia–Phyllagathis clade II as the type of the genus is included in the latter clade. Most species sampled in Phyllagathis spread across eight well supported clades throughout the phylogenetic tree. The type of Phyllagathis showed no close affiliation with other members of Phyllagathis nor its putative relatives. Phyllagathis, as presently circumscribed, is heterogeneous, encompassing multiple evolutionary lineages. As sequence data of nuclear ribosomal internal transcribed spacer and chloroplast trnV‐trnM failed to resolve the phylogenetic relationships among these lineages, the formal taxonomic adjustment of Phyllagathis is postponed until further evidence can be gathered.

“…Fordiophyton , as currently defined, is a small Asian genus of 13 species mainly occurring in southern China, with only one species extending to northern Vietnam (Chen and Renner 2007; Ning and Liu 2010; Zeng et al 2016a, b). It is characterised by 4-merous flowers, eight unequal stamens, distinctly dimorphic anthers, connectives not calcarate at the base and anther base of longer stamens not forked, obtusely forked or forked and curved (Fig.…”

“…1). Ten species of Fordiophyton have been included in previous molecular phylogenetic studies (Zeng et al 2016a, b; Zhou et al in press). Amongst the species sampled in Fordiophyton , F.breviscapum (C. Chen) Y. F. Deng & T. L. Wu appeared to be close to Phyllagathistetrandra Diels and P.elattandra Diels (Zhou et al in press), while the remaining species, including the type species, F.faberi Stapf, formed a well-supported clade close to Blastus , Bredia - Phyllagathis clade 2 and Plagiopetalum (Zeng et al 2016a, b; Zhou et al in press).…”

Fordiophytonjinpingense (Melastomataceae; Sonerileae), a species occurring in south-eastern Yunnan, China, is described as new, based on morphological and molecular data. Phylogenetic analyses, based on nrITS sequence data, showed that, except F.breviscapum, all species sampled in Fordiophyton formed a strongly supported clade in which two geographical lineages were recovered. The generic placement of F.jinpingense is well supported by phylogenetic analyses and a character combination of 4-merous flowers, distinctly dimorphic stamens and the connectives basally not calcarate. Molecular divergence and morphological evidence indicate that F.jinpingense is well separated from other members of the genus, thus justifying its recognition as a distinct species. Fordiophytonjinpingense is phylogenetically closest to F.repens, but differs markedly from the latter in stem morphology (short, obtusely 4-sided vs. long, 4-angular), habit (erect vs. creeping), leaf size (6–16.5 × 4.5–13 cm vs. 4–7.5 × 4–6.5 cm) and flower number per inflorescence (5–13 vs. 3–6).

“…China including about 14 species, accounting for 77.8% of the world, is the distribution center of this genus. Previous studies had performed the phylogenetic position of genus (Clausing et al 2000;Clausing and Renner 2001;Fritsch et al 2004;Zeng, Huang, et al 2016;Zeng, Zou, et al 2016;Zhou, Ng, et al 2018;Zhou, Lin, et al 2018), while interspecific relationship within the genus have not been investigated with molecular tools. In this study, we reported the first complete chloroplast genome of Blastus cochinchinensis based on Illumina sequencing technology, commonly found in southern China, as a resource for future studies of the genus.…”

Blastus Lour. belongs to tribe Sonerileae (Melastomataceae), comprising about 18 species worldwide. Herein, we presented, assembled, and annotated the first complete chloroplast genome of Blastus (B. cochinchinensis). The complete chloroplast genome (cp) size of B. cochinchinensis was 156,005 bp in length, containing a pair of 26,812 bp inverted repeat (IR) regions, which were separated by a large single-copy region (LSC) 85,926 bp and a small single-copy (SSC) region 16,455 bp. The overall GC content of the genome was 37.0%. The whole genome contained 129 unique genes, including 81 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The phylogenetic analysis showed that B. cochinchinens was sister to Barthea barthei. The present study provided B. cochinchinensis genomic information that may be found useful in conservation and molecular phylogenetic studies on Blastus.
