“…We also sampled some recently described species whose phylogenetic relationships are unknown, including Chrysophyllum lancisepalum R.Lima (Lima & al., 2021), C. moralesianum Aguilar & al. (Santamaría‐Aguilar & al., 2016), Pouteria ciliata Alves‐Araújo & M.Alves, P. confusa Alves‐Araújo & M.Alves (Alves‐Araújo & Alves, 2012), and P. synsepala Popovkin & A.D.Faria (Popovkin & al., 2016). In total, 122 terminal taxa were sampled, of which 106 are from the Neotropics, 17 are currently placed in Chrysophyllum , and 40 in Pouteria , all of which are listed with voucher information and GenBank accession numbers in Appendix 1.…”

Classifications of the pantropical plant family Sapotaceae based solely on morphology have historically recognized between 125 and 53 genera. Phylogenetic analyses using molecular data have repeatedly demonstrated that broad concepts of two large genera belonging to subfamily Chrysophylloideae, Chrysophyllum and Pouteria, are untenable and their narrowed delimitations have restricted them to the Neotropics. A recent phylogenetic study proposed further amendments by resurrecting the genera Achrouteria, Cornuella, Lucuma, Martiusella, Nemaluma, Prieurella and Ragala, and questioned the status of three generally accepted genera, Chromolucuma, Pradosia and Sarcaulus. We test this suggested classification using expanded sampling that comprises 122 terminals, including material of 29 of the 34 name‐bringing species for generic names historically regarded as synonyms of Chrysophyllum and Pouteria. We used sequence data from ribosomal nrDNA (ETS, ITS), the nuclear gene RPB2, two cpDNA spacers (petN‐psbM, trnH‐psbA), and indel information to estimate phylogenetic relationships in a Bayesian framework using BEAST. All sequences were newly realigned to test reproducibility, and 26 morphological characters were mapped on the resulting tree. Our analyses recovered three African genera embedded within a large Neotropical clade of Chrysophylloideae. We found strong support for the reinstatement of the seven genera listed above as well as for four other genera, viz. Chloroluma, Englerella, Labatia, and Peteniodendron. This subsequently leads to further amendments of Chrysophyllum and Pouteria, which are now limited to include 25–30 and 7 species, respectively. However, one clade that includes many name‐bringing lineages largely corresponds to Pouteria s.l., a group that needs further phylogenetic research to unravel relationships and generic limits. The hypothesis that Chrysophyllum cuneifolium had an inter‐continental hybrid origin involving genomes from Africa and South America is rejected because it is shown to have been based on erroneous results obtained from a contaminated DNA aliquot. A total of 73 genera are currently recognised in Sapotaceae, 21 of which are Neotropical members of Chrysophylloideae. We update the nomenclature and synonymy of 75 species, make 36 new combinations, and designate lectotypes for 31 names.

“…Ovary contains nine to eleven locules and fruits of large berry containing five large flattened seeds or sometimes fewer by abortion. These Thai Chrysophyllum species are distinguished from other genera in the family Sapotaceae by the presence of uniseriate calyx with five sepals and the absence of staminode (Chayamarit 2014;Inyama et al 2015;Santamaria-Aguilar et al 2016;Sossai et al 2017).…”

Abstract. Prasawang S, Srinual A. 2020. Comparative leaf and wood anatomical characteristics of Chrysophyllum (Sapotaceae) relate to taxonomy of the species in Thailand. Biodiversitas 21: 1578-1587. Anatomical attributes are important tools for taxonomic studies of plants. The present study compared anatomical characteristics (i.e. lamina, petiole and wood) of two species of Chrysophyllum (namely Chrysophyllum cainito L. and C. roxburghii G.Don) belonging to family Sapotaceae in Thailand to develop taxonomic identification keys for two species of Chrysophyllum. Peeling and clearing methods were used for epidermal study, paraffin method for lamina and petiole transverse sections and standard microtome sectioning for anatomical analyses of wood. The findings of this study demonstrated the leaf and wood anatomical features presenting in C. cainito differs from those in the species of C. roxburghii including 1) shape and outline of epidermal cell wall 2) presence or absence of T-shaped trichome 3) presence or absence of inclusions 4) shape of vascular bundle and accessory bundle in midrib 5) shape of petiole and vascular bundle 6) grouping type of vessel 7) type of axial parenchyma 8) presence or absence of inclusions in rays and 9) thickness of fiber walls. Therefore, these characteristics can be used valuably as additional data in case of taxonomic studies of Thai Chrysophyllum.
