利用Z-叠加数字显微镜对南蛇藤属13种植物的雄核进行了形态学研究。而C. ladon缺乏雄锥，其余12种被发现具有扇形雄锥背翅表面。这些物种的雄锥具有以下共同特征：尺寸比标准的产色鳞片小、没有齿状末端和存在横肋穿孔。此外，有些种类的雄核具有独特的显微结构。银杉的雄锥具圆形片状轮廓，而松叶银杉和灰叶银杉的雄锥在基端逐渐变细。银背锦鸡儿和菲律宾锦鸡儿的平均纵脊数（17.1）大于12种锦鸡儿的平均纵脊数（14.3）。这些结果表明，在微域的形态特征，如片状的形状和纵向脊的平均数，是有用的，以确定种南蛇藤属。
Morphological studies of androconia were performed for 13 Celastrina species using a digital microscope with Z-stacking mode. Whereas C.ladon lacked androconia, the remaining 12 species were found to possess fan-shaped androconia on the dorsal wing surfaces. The androconia of these species shared the following common features: smaller size than standard color-producing scales, absence of dentate termini and presence of crossrib perforations. In addition, some species were characterized by unique microstructures in their androconia. The androconia of C.argiolus iynteana possessed a rounded lamellar contour, while those of C.lavendularis himilcon and C.echo cinerea were tapered on the basal end. The average number of longitudinal ridges of C.argiolus ladonides and C.filipjevi (17.1) were greater than the average number of 12 species (14.3). These results suggest that the morphological traits of androconia in microdomain, such as the shape of the lamellar form and the average number of longitudinal ridges, are useful to identify species in the genus Celastrina.
