Sphagnum moss exhibits a super ability to absorb water. However, the water absorption capacity of different species and different parts of the same species is not well understood. In this study, we measured the short-term and saturated water absorption of 21 Sphagnum species from China. The results showed that the water absorption capacity of the investigated peat mosses was much higher than that of other bryophytes. Sphagnum imbricatum had the highest saturated water absorption capacity (about 44 times its dry weight), while the peat moss with the lowest saturated water absorption was Sphagnum flexuosum (about 19 times its dry weight). In addition, we determined the relative volume of hyalocysts of the spreading and pendent branch leaves of 18 Sphagnum species and further measured the water absorption capacity of the pendent branch, spreading branch, and stem of six of them. The results revealed that both pendent and spreading branches had strong water absorption capacity and were the primary water-absorbing parts of peat mosses. The water-absorbing capacity of different Sphagnum species was linearly related to the volume of hyalocysts. The results provide an essential scientific basis for selecting high-quality germplasm resources of peat moss.\u0000 ","PeriodicalId":93270,"journal":{"name":"Bryophyte diversity and evolution","volume":"57 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141108278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within the Lejeuneaceae family, 85 species were known from the country and the new reports increased the total number of species in 27% compared with the last publications. Thus the islands can be distinguished due to the high number of the species of the Lejeuneaceae family that represents about 50% of the country liverwort’s flora.

These features are rare in mosses but shared by a few Grimmia species including sympatric G. alpestris. Sporophyte characteristics of the new taxon, in contrast, indicated a species of Schistidium and suggested a possible intergeneric hybrid origin. Nuclear ITS and plastid rps4‒trnF sequence data consistently resolved the new taxon within species of Schistidium, thus contradicting the hybridogenic hypothesis. We suggest that the shared feature of mammillose cells evolved independently in the two genera in adaptation to similar environmental conditions, possibly prolonged snow cover. Supported by morphological similarity, our phylogenetic analyses indicate a sister relationship of S. mammillosum and S. marginale in the Confertum clade. Schistidium mammillosum colonises siliceous rocks in the alpine and nival zone and is to date known from the French Alps and a single locality in Switzerland.\u0000 ","PeriodicalId":93270,"journal":{"name":"Bryophyte diversity and evolution","volume":"45 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141112244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
