“…An extreme example is here the complete absence of nucleotide differences between cpDNA of S. pennata subsp. ceynowae and S. borysthenica as well as very small differences reaching 0.009% for S. jagnobica and S. richteriana and 0.012% between S. arabica and S. hohenackeriana , despite of the fact that all of the aforementioned species are morphologically well separated and easily identifiable 3 , 5 , 52 . The comparative analysis of complete cpDNA sequences as super-barcodes in the case of Stipa was much more effective than a traditional barcoding approach.…”

Present study was designed to verify which or if any of plastome loci is a hotspot region for mutations and hence might be useful for molecular species identification in feather grasses. 21 newly sequenced complete plastid genomes representing 19 taxa from the genus of Stipa were analyzed in search of the most variable and the most discriminative loci within Stipa. The results showed that the problem with selecting a good barcode locus for feather grasses lies in the very low level of genetic diversity within its plastome. None of the single chloroplast loci is polymorphic enough to play a role of a barcode or a phylogenetic marker for Stipa. The biggest number of taxa was successfully identified by the analysis of 600 bp long DNA fragment comprising a part of rbcL gene, the complete rbcL-rpl23 spacer and a part of rpl23 gene. The effectiveness of multi-locus barcode composed of six best-performing loci for Stipa (ndhH, rpl23, ndhF-rpl32, rpl32-ccsA, psbK-psbI and petA-psbJ) didn’t reach 70% of analyzed taxa. The analysis of complete plastome sequences as a super-barcode for Stipa although much more effective, still didn’t allow for discrimination of all the analyzed taxa of feather grasses.

“…) Stipa boryshtenica is a widely distributed taxon ranging from central Europe to central Asia (Tzvelev 1976, Martinovský 1980, Conert 1998, Gonzalo et al 2013 and is here reported for the first time from China. Having the ventral line of hairs at the anthecium at the distance of (1.6-)4.2-6.1(-7.7) mm not reaching the base of awn and almost glabrous to slightly scabrous vegetative leaves, S. boryshtenica is close to S. pennata, however they differ by having callus base narrowly cuneate vs. pyriform, callus (3.4-)3.7-4.2(-4.6) vs. (2.4-)2.8-3.25(-3.75) mm long, upper cauline leaves (22-)36-62(-125) vs. (4-)10-22(-40) mm long respectively (Klichowska & Nobis 2016). These two taxa also differ in the type of habitat in which they grow.…”

Stipa dickorei sp. nov. from the Western Tibetan Plateau (China) is described. The new species is morphologically similar to S. regeliana, but they differ from each other in the length of ligules of vegetative shoots. Stipa dickorei is also similar to S. aliena, however they differ in the shape of panicle, which is contracted with straight branches in S. dickorei, and lax with flexuous branches in S. aliena. Images of macromorphological and micromorphological structures of the new taxon are provided. Additionally, new records of S. borysthenica, S. richteriana, and S. zalesskii, species not listed in the recent Flora of China, as well as a checklist of Chinese feather grasses are also presented.

Stipa pennata (Poaceae), has become a rare and endangered species in Central Europe due habitat loss and fragmentation. This species is characterized by high morphological variability, which has resulted in the description of numerous intraspecific taxa. The aim of present work is to develop microsatellite markers useful in population genetics studies as well as in intraspecific taxonomy of S. pennata s.l. We developed ten microsatellite markers using Illumina high-throughput. Polymorphism at each marker was evaluated using 4–15 individuals from four morphotypes of S. pennata s.l. Seven markers showed polymorphism while three were monomorphic. The number of alleles per locus ranged from 7 to 12, and the observed and expected heterozygosity varied from 0.000 to 1.000 and 0.000 to 0.8670, respectively. Our results confirm that three of four studied morphotypes are genetically distinct. The microsatellite markers developed here will be useful for evaluating levels of genetic diversity and differentiation, to study gene flow, population dynamics and in future conservation studies as well as for intraspecific delimitation of morphologically similar taxa within S. pennata s.l.
