In addition, since Prinsepia utilis has angulaperturate pollen grains in the early stage of pollen development and shars the same character with two taxa Geissois montana and Cunonia capensis under Cunoniaceae, the pollen morphological data supports the viewpoint that Rosaceae may have a systematic relationship with Cunoniaceae under Saxifragales.

此外，由于Prinsepia utilis的花粉在其发育初期具角萌发孔花粉，与Cunoniaceae下的两个类群Geissois montana和Cunonia capensis具有相同的特征，故花粉形态特征在一定程度上支持Rosaceae可能和虎耳草目中的Cunoniaceae有一定系统学联系的观点。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
