The three-dimensional structure of the endothecial thickenings in the anthers was investigated in 87 species from 70 genera, chosen to provide representative coverage of the families Cyperaceae, Restionaceae, Anarthriaceae, Ecdeiocoleaceae, Centrolepidaceae, Joinvilleaceae, Flagellariaceae, Poaceae, Xyridaceae, and Eriocaulaceae. There is complex variation in the patterns of endothecial thickening: the Eriocaulaceae, Flagellariaceae, and most Poaceae have thickenings with a complete baseplate; the Cyperaceae and most of the Restionaceae are characterized by helical thickenings; some genera in the Bambusoideae have annular thickenings; and U-shaped thickenings occur in the Xyridaceae and Eriocaulaceae and in some Poaceae and Restionaceae. Joinvillea and Ecdeiocolea have unique thickening types. Endothecial characters were subjected to cladistic analysis. Including endothecial characters in an existing cladogram of the group indicates that there is no single, well-corroborated cladogram available for the Poales/Restionales.
对来自70个属的87个物种的花药内皮层增厚的三维结构进行了研究，这些物种的选取旨在全面代表莎草科、帚灯草科、无芒草科、旱叶草科、刺鳞草科、田葱科、鞭藤科、禾本科、黄眼草科和谷精草科。内皮层增厚模式存在复杂的变异：谷精草科、鞭藤科和大多数禾本科具有带有完整基板的增厚；莎草科和大多数帚灯草科的特征是螺旋状增厚；竹亚科的一些属具有环状增厚；U形增厚出现在黄眼草科和谷精草科以及一些禾本科和帚灯草科中。田葱属和旱叶草属具有独特的增厚类型。对内皮层特征进行了分支分析。将内皮层特征纳入该类群现有的分支图表明，对于禾本目/帚灯草目没有单一的、得到充分证实的分支图。
