“…With the above conflicting issues, we agree with the proposal to conserve the name Eriobotrya against Rhaphiolepis (Shaw 2020). In this proposition, Shaw (2020) stressed the importance of maintaining nomenclatural stability of Eriobotrya species with horticultural and agricultural value, in particular E. japonica, which just months after the publication by Liu et al (2020a), received another name combination (i.e. E. japonica to R. loquata Liu & Wen in Liu et al (2020a: 11) to R. bibas (Lour.)…”

Eriobotrya shanense, a new species from the karst region of Shan State, eastern Myanmar, is described and illustrated. This evergreen tree is similar to the autumn and winter-flowering, large-leaved species E. malipoensis and E. japonica by having tomentose hairs on the abaxial leaf surface, but can be distinguished by its obovate, widely obelliptic or oval blade shape, leaf length-width ratio of 2:1 (vs. 3:1), and rounded or obtuse apex (vs. acute). The species also resembles less-known, undercollected Myanmar broad-leaved species E. wardii and E. platyphylla in leaf shape and length-width ratio, but can be easily differentiated by the presence of tomentose hairs on the leaves, and inflorescence. Phylogenetic analysis based on nrDNA ITS region supported its close affinity with E. malipoensis and E. japonica. Molecular data also generally grouped the 17 congeneric taxa accessions in congruence to their leaf morphology, with the entire Eriobotrya clade strongly supported to be monophyletic and separate from Rhaphiolepis.

“…The two genera can be well separated according to whether the sepals fall off and whether there is an annular ring after sepal senescence or not ( Supplementary Table S5 and Supplementary Figure S9 ). In addition, Shaw (2020) stressed the importance of maintaining nomenclatural stability for Eriobotrya species with horticultural and agricultural value. Because of the conflicting issues we have found, we do not recommend Eriobotrya being incorporated into the genus Rhaphiolepis .…”

Eriobotrya (Rosaceae) is an economically important genus with around 30 species. It is widely distributed in tropical and warm temperate regions of Asia, with most of its species in China, Myanmar, and Vietnam. However, Eriobotrya is often confused with the smaller genus Rhaphiolepis, and the phylogenetic relationships between the two genera are controversial. Here we present phylogenetic analyses of 38 newly generated Eriobotrya and Rhaphiolepis nrDNA together with 16 sequences of nrDNA and 28 sequences of ITS obtained from GenBank, representing 28 species of Eriobotrya and 12 species of Rhaphiolepis, in order to reconstruct highly supported relationships for the two genera. Contrary to previous research based on limited sampling, our results highlight the monophyly of Eriobotrya as well as Rhaphiolepis. The topology recovered here is consistent with key morphological synapomorphies such as the persistent sepals in Eriobotrya. Our findings show that increased sampling of taxa can provide a more robust phylogeny through reducing phylogenetic error and increasing overall phylogenetic accuracy.

“…The phylogenomic analysis by Liu et al (2020) revealed that Rhaphiolepis and Eriobotrya strongly supported the paraphyly of Eriobotrya, with Rhaphiolepis nested within it and Eriobotrya was embedded in Rhaphiolepis. Shaw (2020) conserved the name Eriobotrya against Rhaphiolepis and concluded that the epithet japonica was preoccupied and the name of the panglobal loquat changes both in its genus and specific epithet. The replacement name Rhaphiolepis loquata (Liu et al 2020) The two genera can be distinguished from each other by the following morphological c h a r a c t e r s ; t h e p r i m a r y l a t e r a l v e i n s reaching at the leaf margin, often in a tooth (Craspedodromous) in Eriobotrya, whereas the primary veins consistently end without reaching the margins (Camptodromous) in Rhaphiolepis; the inflorescence are paniculate in Eriobotrya and racemose in Rhaphiolepis; flower white and carpels (2 or) 3-5 in Eriobotrya, whereas flower pink and carpels ) (-1) 2 in Rhaphiolepis; the sepals are persistent on the fruits in Eriobotrya, while in Rhaphiolepis, the sepals are early deciduous, leaving an annular ring at the summit of the fruit (Gu & Spongberg 2003).…”

The phylogenetic relationships of Eriobotrya were examined based on cpDNA psbA-trnH and atpB-rbcL markers using 21 names with M. germanica, P. beauverdiana and R. indica as an outgroup. The results revealed that the sequencing analysis contained around 841 bp aligned DNA characters, where 81 bp were variables and 42 bp were informative polymorphic sites. Further analysis showed that the phylogeny tree divided the species of Eriobotrya into 4 clades. Eriobotrya bengalensis, E. bengaensis var. angustifolia and E. obovata were closely related and formed clade A. E. deflexa, E. fragrans and E. seguinii clustered into clade B. E. japonica, E. malipoensis and E. × daduheensis clustered into clade C and E. fusca, E. cavaleriei, E. tengyuehensis, E. condaoensis, E. serrata, E. hookeriana, E. petiolata, E. salwinensis and E. elliptica were clustered into clade D. The present study concluded that future research with more taxa and the use of more DNA barcoding markers may be needed to resolve the complete phylogeny and evolution of Eriobotrya.
