A study of leaf anatomy, chloroplast ultrastructure, labelling pattern after short-time (14)CO2 fixation, and CO2 compensation point indicates that Chamaesyce buxifolia (Engelm. ex Hitche.) Small (Geraniales), Pectis leptocephala (Cass.) Urb. (Campanulales), and Imperata arundinacea Cyr. (Graminales) have typical features of plants exhibiting the C4-dicarboxylic acid pathway of photosynthesis. Thus it is established that the correlation of these C4 properties, well known in various orders of Monocotyledons (Graminales, Cyperales) and in the dicotyledonous order of the Centrospermae, is also characteristic of some species in other systematically widely separated orders within the Dicotyledons.
一项关于叶片解剖结构、叶绿体超微结构、短时间（14）CO₂固定后的标记模式以及CO₂补偿点的研究表明，小叶地锦（Engelm. ex Hitche.）Small（牻牛儿苗目）、细叶佩蒂菊（Cass.）Urb.（桔梗目）和白茅（Graminales）具有表现出C4-二羧酸光合作用途径的植物的典型特征。因此，可以确定，这些在单子叶植物的各个目（禾本科、莎草目）以及双子叶植物中央种子目的某些物种中广为人知的C4特性之间的相关性，在双子叶植物中其他系统上广泛分离的目里的一些物种中也具有特征性。
