Euphorbiaceae comprise more than 200 genera and three subfamilies of Acalyphoideae, Euphorbioideae and Crotonoideae. We have observed chromosomes of 40 species in 37 genera. Among 37 genera, chromosomes of the following 13 genera were observed for the first time in this study: Adelia (2n=40), Agrostistachs (2n=22), Blumerodendron (2n=22), Chaetocarpus (2n=36), Elateriospermum (2n=36), Koilodepas (2n=24), Neoscortechinia (2n=24), Omphalea (2n=32), Strophioblachia (2n=20), Sumbviopsis (2n=22), Pimeleodendron (2n=22), Strophioblacia (2n=20) and Trigonostemon (2n=26). Additionally, revised new chromosome numbers have counted here in the following five species of five genera: Alchornea (2n=72), Codiaeum (2n=128), Dalechampia (2n=88), Homalanthus (2n=154) and Tragia (2n=42).Among the families related to Euphorbiaceae in Malpigiales, we have observed chromosomes of 30 species of 27 genera in 14 families. Of 27 genera, chromosomes of seven genera of Breynia (2n=52) in Phyllanthaceae, Irvingia (2n=30) in Irvingiaceae, Ixonanthes (2n=28) in Ixonanthaceae, Lacistema (2n=44) in Lacistemaceae, Microdesmis (2n=30) in Pandaceae and Picrodendron (2n=44) in Picrodendraceae were observed for the first time in this study. The revised new chromosome numbers have been ocounted here in the following five genera: Adenia (2n=22) in Passifloraceae, Casearia (2n=22) in Salicaceae, Heteropteris (2n=20) in Malpigiaceae, Ochna (2n=50) in Ochnaceae and Stigmaphyllon in Malpigiaceae. In the present study, we have observed chromosomes of 70 species of 64 genera in 14 families of Malpigiales. Among them, we have observed chromosomes of 20 species of 19 genera in six families for the first time in this study.

大戟科包括铁苋菜亚科、大戟亚科和巴豆亚科3个亚科200多个属。对37属40种植物的染色体进行了观察。在37个属中，以下13个属的染色体是本研究首次观察到的：Adelia（2n=40）、剪股颖属（2n = 22）、Blumerodendron（2n=22）、Chaetocarpus（2n = 36）、Elateriospermum（2n=36）、Koilodepas（2n = 24）、Neoscortechinia（2n = 24）、Omphalea（2n=32）、Strophioblachia（2n=20）、2n=22）、松属（Pimeleodendron）（2n=22）、糙叶藓属（Strophioblacia）（2n=20）和三棱木属（Trigonostemon）（2n=26）。此外，还对五属五种植物的染色体数目进行了修正，分别为：Alchornea（2n=72）、Codiaeum（2n=128）、Dalechampia（2n=88）、Homalanthus（2n=154）和Tragia（2n=42）。在27个属中，首次观察到叶下珠科黑面榄属（2n=52）、欧文氏花属（2n=30）、苦碟子科Ixonanthes（2n=28）、Lacistemae的Lacistema（2n=44）、熊猫科Microdesmis（2n=30）和胡黄连科Picrodendron（2n=44）等7个属的染色体。本文对西番莲科的沙参属（Adenia，2n=22）、杨柳科的干酪根属（Casearia，2n = 22）、金雀花科的异蕨属（Heteropteris，2n=20）、赭石属（Ochna，2n=50）和金雀花科的柱头蕨属（Stigmaphyllon，2n=50）等五个属的染色体数目进行了订正。本文对垂枝花目14科64属70种植物的染色体进行了观察。其中，首次对6科19属20种植物的染色体进行了观察。
