关于石竹科毛状体多样性和分布的信息很少，目前的工作旨在填补这一知识空白。在目前的工作中，研究了属于 19 属的 62 个分类单元。为了分析毛状体多样性和外貌类型，将干燥的植物标本用水再水化。毛状体的最终插图是使用透明相机制作的。研究类群中报告了六种类型的毛状体，即单细胞无腺体、单细胞腺体、多细胞单列腺体、多细胞单列无腺体、多细胞无腺体分叉和多细胞多列无腺体毛状体。毛状体的多样性及其分布在石竹科属属或部落水平的分类学界定中没有发挥任何重要作用。尽管如此，很少有密切相关的物种可以根据毛状体或衣饰图案来区分彼此。
Information about trichomes diversity and distribution of the family Caryophyllaceae is rare and the present work is intended to fill this knowledge lacuna. In the present work 62 taxa belonging to 19 genera were studied. For the analysis of trichomes diversity and vestiture type, dried plant specimens were rehydrated with water. The final illustrations of trichomes were made by using camera lucida. Six types of trichomes viz., Unicellular eglandular, Unicellular glandular, Multicellular uniseriate glandular, Multicellular uniseriate eglandular, Multicellular eglandular bifurcate and Multicellular multiseriate eglandular trichomes reported in the studied taxa. Diversity of trichome and their distribution does not play any significant role in the taxonomic delimitation either generic or tribal level of the family Caryophyllaceae. Although, few closely allied species can be distinguished from each other either on the basis of the presence of trichomes or vestiture patterns.
