疏穗苔草（Carexremotistachya）、疏穗苔草C. daxinensis和C.本文描述了中国新记录种fangiana。疏穗苔草（Carex remotistachya）与C. doniana（sect. Molliculae），不同之处在于穗状花序远，雄花穗状花序基部有3-5厘米长的花序梗，叶宽3-6毫米，柱头短于周蕊花。大新苔草（Carexdaxinensis）与C.不同之处在于：花被果椭圆形卵圆形，长4-4.5 mm，穗状花序的雄蕊部分短于雌蕊部分，叶宽2-3.5 mm。苔草（Carexfangiana）与C. nitidiutriculata（Sect. Hymenochlaenae），不同之处在于叶宽6-9毫米，雄穗单生，周果木无毛。
Carex remotistachya, C. daxinensis and C. fangiana, three new species from China, are described and illustrated. Carex remotistachya resembles C. doniana (sect. Molliculae), differing by having spikes remote, staminate spikes with a 3-5 cm long peduncle at the base, leaves 3-6 mm wide, and stigmas shorter than perigynia. Carex daxinensis is similar to C. caudispicata (sect. Radicales), but differs in having perigynia ellipsoid-ovoid, 4-4.5 mm long, staminate parts of spikes shorter than pistillate ones, and leaves 2-3.5 mm wide. Carex fangiana is similar to C. nitidiutriculata (sect. Hymenochlaenae), differing by having leaves 6-9 mm wide, staminate spike solitary, and perigynia glabrous.
