The plants of the families of Aegilopaceae Martinov and Andropogonaceae Martinov (Scutellopsida D.L.Fu) are closely related to human production and daily life, due to the important crops like wheat, maize, and sugarcane within the families. For familiar plants within the families, taxonomists tend to favor widely used names and more detailed classifications, which can result in taxonomic confusions of hierarchy. Using the minimum criterion PHS (phylogenetic similarity) ≤ 0.928 (inter genera) for genus classification by CPCG (chloroplast complete genomes) of Fructophyta D.L.Fu & H. Fu, total 14 current synonyms of seven genera of Andropogonaceae and 14 current synonyms of three genera of Aegilopaceae have been identified, 4 current synonyms of &lt;i&gt;Saccharum&lt;/i&gt; L. including &lt;i&gt;Erianthus &lt;/i&gt;Michaux., &lt;i&gt;Imperata &lt;/i&gt;Cirillo, &lt;i&gt;Miscanthus &lt;/i&gt;Andersson and &lt;i&gt;Tripidium &lt;/i&gt;H. Schol, 1 synonym of &lt;i&gt;Iseilema&lt;/i&gt; Andersson being &lt;i&gt;Eremopogon&lt;/i&gt; Stapf, 5 synonyms of &lt;i&gt;Dichanthium&lt;/i&gt; P. Willemet being &lt;i&gt;Agenium &lt;/i&gt;Nees, &lt;i&gt;Bothriochloa&lt;/i&gt; Kuntze, &lt;i&gt;Capillipedium&lt;/i&gt; Stapf, &lt;i&gt;Euclasta&lt;/i&gt; Franch. and &lt;i&gt;Pseudanthistiria&lt;/i&gt; Hook. f., 1 synonym of &lt;i&gt;Anatherum&lt;/i&gt; P. Beauv. being &lt;i&gt;Elymandra &lt;/i&gt;Stapf, 1 synonym of &lt;i&gt;Hyparrhenia&lt;/i&gt; Anderss. ex Fourn being &lt;i&gt;Hyperthelia &lt;/i&gt;Clayton, 1 synonym of &lt;i&gt;Zea&lt;/i&gt; L. being &lt;i&gt;Tripsacum&lt;/i&gt; L., 1 synonym of &lt;i&gt;Arthraxon&lt;/i&gt; P. Beauv. being &lt;i&gt;Microstegium&lt;/i&gt; Nees, 10 synonyms of &lt;i&gt;Cinna&lt;/i&gt; L. being &lt;i&gt;Anthosachne &lt;/i&gt;Steud., &lt;i&gt;Australopyrum &lt;/i&gt;(Tzvelev) Á. Löve, &lt;i&gt;Campeiostachys &lt;/i&gt;Drobow, &lt;i&gt;Connorochloa &lt;/i&gt;Barkworth, S. W. L. Jacobs & H. Q. Zhang, &lt;i&gt;Dasypyrum&lt;/i&gt; (Coss. & Durieu) T. Durand, &lt;i&gt;Douglasdeweya &lt;/i&gt;C. Yen, J. L. Yang & B. R. Baum, &lt;i&gt;Kengyilia &lt;/i&gt;C. Yen & J. L. Yang, &lt;i&gt;Pascopyrum &lt;/i&gt;Á. Löve, &lt;i&gt;Pseudoroegneria&lt;/i&gt; (Nevski) Á. Löve and &lt;i&gt;Thinopyrum &lt;/i&gt;Á. Löve, 1 synonym of &lt;i&gt;Agropyron &lt;/i&gt;Gaertn. being &lt;i&gt;Eremopyrum&lt;/i&gt; Jaub. & Spach, 3 synonyms of&lt;i&gt; Aegilops&lt;/i&gt; L. being &lt;i&gt;Crithopsis&lt;/i&gt; Jaub. & Spach, &lt;i&gt;Taeniatherum&lt;/i&gt; Nevski and &lt;i&gt;Triticum&lt;/i&gt; L. Additionally, 17 new specific names such as &lt;i&gt;Agropyron qinghaica&lt;/i&gt; D.L.Fu,&lt;i&gt; Arthraxon yunnanensis&lt;/i&gt; D.L.Fu,&lt;i&gt; Hyparrhenia steudelii&lt;/i&gt; D.L.Fu, &lt;i&gt;Elymus brownei&lt;/i&gt; Kunth ex D.L.Fu and&lt;i&gt; Saccharum liuanum&lt;/i&gt; D.L.Fu, along with 221 new specific combinations like&lt;i&gt; Aegilops aestiva&lt;/i&gt; (L.) D.L.Fu, &lt;i&gt;Anatherum&lt;/i&gt; &lt;i&gt;bicorne&lt;/i&gt; (L.) D.L.Fu, &lt;i&gt;Dichanthium alpinum&lt;/i&gt; (H.

These publications will effectively resolve taxonomic nomenclature confusions in a scientific manner and establish a solid foundation for evolutionary system research within the new class Scutellopsida D.L.Fu.
