最近在中国浙江省的野外调查揭示了该地区苔草属分类的新见解。本文描述了密花苔草组一新种--红林苔草。它不同于C。pseudodispalata在有周果核广泛倒卵球形，收缩成一个约。0.5至0.7毫米长喙在先端，和雄花鳞片渐尖。穗穗苔草subglabra（sect. Confertiflorae）上升为种级，并合并为C.亚光滑的最后，一个新的亚种，苔草scopulus（subsp。aristata; Sect. Mitratae）。这个新亚种与模式亚种的不同之处在于具有雌蕊鳞片，顶端有1 - 4毫米长的粗糙芒，叶子宽1.5 - 2.5毫米。
Recent fieldwork in the Chinese province of Zhejiang revealed new insights into the taxonomy of the genus Carex in this area. Carex honglinii, a new species of Carex sect. Confertiflorae, is described. It differs from C. pseudodispalata in having perigynia broadly obovoid, contracted into a ca. 0.5‒0.7 mm long beak at the apex, and staminate scales acuminate. Carex nemostachys var. subglabra (sect. Confertiflorae) is raised to specific rank and combined as C. subglabra. Eventually, a new subspecies of Carex scopulus (subsp. aristata; sect. Mitratae) is described. This new subspecies differs from the type subspecies in having pistillate scales with a 1‒4 mm long apical scabrous awn, and leaves 1.5‒2.5 wide.
