Pollen of 110 species representing 64 genera from 17 of the 18 tribes in the Acalyphoideae (sensu Webster, 1989) was examined in SEM and TEM.This subfamily is palynologically diverse. The Cheiloseae (Cheilosa) have spinulate tricolporate pollen. In the Chrozophoreae, Ditaxis has unique bilateral pollen with two zonapertures. In the Pycnocomeae, Pycnocomas has a complete tectum with spinules in a reticulate pattern and Argomuellera is finely or reticulate or microreticulate. The Adelieae and the Alchornieae share operculate tricolporate pollen. The Acalypheae have heterogenous pollen grains with various exine sculptures and structures. The Dalechampieae are characterized by reticulate exines. The Pereae have unusual exine structure composed of interwoven columellae. Most Acalyphoideae have colporate apertures, but the number of apertures varies. The wide range of pollen diversity suggests that the subfamily Acalypohoideae is a polyphyletic taxon including several heterogeneous groups.

用扫描电镜和透射电镜观察了金合欢亚科（Acalyphoideae，韦伯斯特，1989）18族中17族64属110种植物的花粉。Cheiloseae（Cheilosa）具有刺状三沟花粉。在光萼藓属中，Ditaxis具有独特的双侧花粉，具有两个花粉带孔。在Pycnocomeae中，Pycnocomas有一个完整的顶盖，具有网状图案的小刺，Argomuellera是细或网状或微网状的。Adelieae和Alchornieae共享具盖的三沟花粉。金合欢属植物花粉粒异质，外壁雕刻和结构多种多样。Dalechampieae的特征是具有网状外壁。该种外壁结构独特，由柱状细胞交织而成。大多数铁苋菜亚科植物都有沟孔，但沟孔的数量各不相同。广泛的花粉多样性表明铁苋菜亚科是一个多系分类单元，包括几个异质群。
