摘要: ABSTRACTIsolepis R.Br. (Cyperaceae) is a genus of aquatic, wetland, or ephemeral sedges that comprises 76 species, mostly in the southern hemisphere, especially Africa and Australasia. Isolepis crassiuscula Hook.f., lenticularis producta (C.B. Clarke) K.L.Wilson are among Australasian members morphologically well-defined subgenus Fluitantes. Specimens belonging to this subgenus, collected from Mount Tongariro, New Zealand, showed ambiguous yet somewhat intermediate morphology compared with these three species. We sequenced directly, cloned sequenced, nuclear DNA (nrITS) chloroplast (rbcL, rps16 trnL) regions collections samples aforementioned species Ribotypes haplotypes were resolve if Tongariro collection was hybrid origin and, so, address which may have been involved hybridisation event. The plants had species-specif...
