Due to the complicated evolutionary history in Pourthiaea, ninety-seven taxa have been described since 1784, and ninety-one of them are validly published taxa, five are naked names, and one is an invalid name. After a comprehensive and critical evaluation, 213 names have been published, including new combinations, new status, and new names; this may be due to the controversial taxonomic position of Pourthiaea in the apple tribe, Maleae. We herewith provide a taxonomic checklist of Pourthiaea for further taxonomic and evolutionary studies. We also lectotypify two taxa: Photinia amphidoxa var. stylosa and P. glabra var. fokienensis.

 Introduction

Pourthiaea Decne. (Maleae, Rosaceae) is a small genus of deciduous shrubs or trees distributed from East to Southeast Asia (Kuan and Yu 1974; Gu and Spongberg 2003). The taxonomic identity of Pourthiaea has been controversial for decades, either as a section of Photinia Lindl. (Kuan and Yu 1974; Robertson et al. 1991; Gu and Spongberg 2003; Campbell et al. 2007; Potter et al. 2007), or a synonym of Aronia Medik. (Kalkman 2004), or a separate genus Pourthiaea (Iketani and Ohashi 1991; Guo et al. 2011; Liu et al. 2019, 2022). The controversial taxonomic status of Pourthiaea makes the published names unstable regarding generic membership. According to our comprehensive review in the present study, nearly 213 names, including new combinations, new statuses, and new names, exist in the literature, representing 91 validly published taxa. For example, a deciduous shrub species endemic to South China was described as Photinia benthamiana Hance in 1866. This taxon was then transferred either to Pourthiaea as P. benthamiana (Hance) Nakai in 1916 or to Stranvaesia as S. benthamiana (Hance) Merr. in 1917, as well as Pyrus as P. benthamiana (Hance) M.F.Fay & Christenh. in 2018.

Several recent phylogenetic studies have struggled to resolve the phylogenetic relationship between Pourthiaea and its closely related genera. Guo et al. (2011) firstly confirmed the monophyly of Pourthiaea using two plastid regions (trnL-trnF and psbA-trnH) and nuclear ribosomal ITS sequences. Unfortunately, they did not resolve the phylogenetic relationships between Pourthiaea and its relatives due to limited informative sites and taxon sampling. Based on transcriptomic data, Xiang et al. (2017) recovered a sister relationship between Pourthiaea and a combined clade, including Chaenomeles Lindl., Cydonia Mill., and Pseudocydonia (C.K.Schneid.) C.K.Schneid. Furthermore, results from the whole plastome and/or plastid regions (Liu et al. 2019, 2020a, 2020b, 2022) supported a close relationship between Pourthiaea and part of Malus Mill., i.e., the Eastern North American and Mediterranean Europe clade (clade II of figure 5 in Liu et al. 2022). However, the nuclear phylogeny inferred from 785 single-copy nuclear genes in our recent study (Liu et al. 2022) supported a close relationship between Pourthiaea and a combined clade, Cydonia and Pseudocydonia, not including Chaenomeles, contradicting Xiang et al. (2017)’s result inferred from transcriptomic data. The discordant phylogenetic position between nuclear and plastid topologies indicated a possible chloroplast capture event in the evolutionary history of Pourthiaea (Liu et al. 2022). This series of phylogenetic and phylogenomic studies confidently resolved the monophyly and phylogenetic position of Pourthiaea. In addition, the monophyly of Pourthiaea was also supported by some morphological characters, such as deciduous leaves, warty peduncles and pedicels, Kribs’III-I heterogeneous rays in the wood, and clusters of stone cells surrounded by parenchymatous cells in the flesh of pomes (Iketani and Ohashi 1991; Lu et al. 1991; Zhang 1992).

Liu et al. (2019) provided a robust phylogeny of the Photinia complex using whole plastomes and entire nuclear ribosomal DNA (nrDNA) sequences with a comprehensive taxon sampling. They proposed a redefined generic circumscription of Pourthiaea, transferring two species and a variety of Stranvaesia Lindl. to Pourthiaea, i.e., S. amphidoxa C.K.Schneid., S. amphidoxa var. amphileia (Hand.-Mazz.) T.T.Yu, and S. tomentosa T.T.Yu & T.C.Ku. Unfortunately, Guo et al. (2020) repeated these new taxonomic combinations, resulting in three illegitimate later homonyms. Recent systematic studies confidently resolved the generic circumscription of Pourthiaea, including all members of the previously recognized Photinia sect. Pourthiaea C.K.Schneid. and three newly transferred taxa from Stranvaesia (Guo et al. 2011, 2020; Liu et al. 2019, 2020a, 2020b, 2022). Furthermore, species delimitation within Pourthiaea has been controversial. Recent taxonomic treatments in Pourthiaea have been proposed solely from morphological evidence, either narrowly circumscribed (Kuan and Yu 1974; Gu and Spongberg 2003) or broadly circumscribed (Liu and Hong 2016a, 2016b, 2017). However, our recent phylogenomic evidence did not support these two proposals (unpublished data), indicating the need for an updated species delimitation in Pourthiaea. Hybridization, allopolyploidy, and apomixis have promoted the diversification of the apple tribe Maleae (Campbell et al. 1991; Robertson et al. 1991; Kalkman 2004; Liu et al. 2022). These complex evolutionary processes extensively diversified the genetic and morphological resources and greatly challenged the species delimitation in Pourthiaea. It is still premature to confidently delimit species in Pourthiaea.

Evaluating all the names published in Pourthiaea is the first step and will be helpful for further species delimitation. In this study, we made a comprehensive checklist of Pourthiaea. It should be noted that the checklist defined in this study is a summary of taxa (97) related to Pourthiaea rather than the species recognized currently in Pourthiaea, and these taxa have been described under Crataegus L., Myrtus L., Photinia, Pourthiaea, Pyrus, Viburnum L., and Stranvaesia. This checklist will provide a solid foundation for future taxonomic and evolutionary studies. In the genomic age, integrating hundreds of nuclear genes, plastomes and morphological characters make it possible to explore species delimitation in lineages with complicated evolutionary histories (Liu et al. 2021, 2022; Su et al. 2021).

 Materials and methods

To comprehensively explore all the names published under Pourthiaea and other related genera, we took over nine years (2013–2021) for this taxonomic study. We reviewed all names in the online databases, such as Tropicos (https://www.tropicos.org), IPNI (https://www.ipni.org/), The Plant List (http://www.theplantlist.org/), as well as all the literature related to Pourthiaea. In addition, we evaluated the validity of all names based on the Shenzhen Code (Turland et al. 2018). A total of 568 type specimens were checked; they are from the following 54 herbaria: A, AU, BNU, BM, BO, CDBI, CSFI, E, GH, GXMI, GZAC, HBG, HENU, HGAS, HHBG, HIB, HIMC, HITBC, HTC, HUST, HX, HZU, IBK, IBSC, JJF, JN, JXAU, K, KUN, KYO, L, LBG, M, N, NAS, NKU, NTUF, NY, P, PE, PH, QTPMB, SM, SNU, SYS, SZ, TAI, TI, U, UPS, US, WUK, ZJFC, and ZM, and the herbarium code followed the Index Herbariorum (http://sweetgum.nybg.org/science/ih/) hosted by New York Botanical Garden.

 Results

We reviewed 213 names published in Pourthiaea and its related genera, and they belong to 91 validly published taxa, five naked names, and one invalid name. We also lectotypified two taxa, i.e., Photinia amphidoxa var. stylosa and P. glabra var. fokienensis. All these names in Pourthiaea have been arranged chronologically in the following text.
