通过形态学和系统发育学研究，将青城山卷柏（Selaginella qingchengshanensis）命名为青城山卷柏（Selaginella）一新种。描述了中国四川的异穗草属植物。新种与S. Amblyphylla，但具有不育的叶，边缘具小齿至稍具缘毛，在现存植物中，背生叶具长芒（与叶等长），垂直于茎和枝，腋生叶三角状卵形或宽卵形。基于ITS+5.8S和rbcL数据的分子分析也支持它是一个独立的种。
Based on morphological and phylogenetic studies, Selaginella qingchengshanensis, a new species in S. sect. Heterostachys from Sichuan, China is described and illustrated. Morphologically, the new species is similar to S. amblyphylla, but has sterile leaves with denticulate to slightly ciliate margins, dorsal leaves with long arista (as long as leaves) perpendicular to stems and branches in living plants, and axillary leaves triangular-ovate or broadly ovate. Molecular analyses based on ITS+5.8S and rbcL data also support it as a distinct species.
