A putatively monophyletic group of annual Silene species is revised taxonomically and described as the new section S. sect. Arenosae. The species of this section were previously treated as a part of a widely circumscribed and polyphyletic S. sect. Rigidulae. Silene sect. Arenosae as circumscribed here consists of nine species. Members of the section show a predominantly E Mediterranean to SW Asian distribution pattern from Turkey southward to Egypt and eastward to Iran and Pakistan, although most of the species have a limited distribution range. The species of S. sect. Arenosae are characterized by narrowly lanceolate calyx teeth, which are often highly polymorphic, and lanceolate to oblanceolate (non-spathulate) basal leaves. The provided taxonomic revision is based on morphological characters and supported by phylogenetic analyses of two nuclear loci (nrITS and an intron of the RPB2 gene) and one chloroplast locus (the intron of the rps16 gene). The species descriptions are formalized using a novel implementation of the Prometheus Description Model.

Silene物种的系统发育和物种定界。Arenosae（石竹科）：一个新的部分

推定的一年生Silene物种的单系群在分类学上进行了修订，并被描述为新的S. sect节。肾上腺。该部分的物种先前已被视为广泛限定和多系的S.教派的一部分。刚毛。甲硅烷派。此处限定的肾上腺有九种。该部分的成员显示了从土耳其向南到埃及，向东到伊朗和巴基斯坦的东地中海到西南亚的分布格局，尽管大多数物种的分布范围有限。S.教派的种类。Arenosae的特征是通常具高度多态性的狭披针形的花萼牙齿，以及披针形的到倒披针形的（无无刺的）基生叶。提供的分类学修订基于形态特征，并通过系统发育分析支持了两个核基因座（nrITS和RPB2基因的一个内含子）和一个叶绿体基因座（rps16基因的内含子）。物种描述使用Prometheus描述模型的新颖实现形式化。
