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.

在SEM和TEM中检查了110种代表来自18个部落中17个部落中17个部落中17个属的花粉。 Cheiloseae（Cheilosa）具有旋转的三环孢子花粉。在chrozophoreae中，二苯二胺具有独特的双侧花粉，并具有两个Zonapertures。在pycnocomeae中，pycnocomas具有一个完整的底膜，具有网状模式，而Argomuellera则是细微的，是网状或网状或微透明的。 Adelieae和Alchornieae共享具有三环孢子花粉。 a麦具有各种外部雕塑和结构的异质花粉颗粒。 Dalechampieae的特征是网状外观。 Pereae的外观结构不寻常。大多数a型科有腔孔，但孔的数量有所不同。多种花粉多样性表明，亚家族的丙型巴达科是一个多形分类群，其中包括几个异质基团。
