Sphagnum moss (peat moss) is the dominant land plant in peatlands, and it plays an essential role in peatland ecosystems because its remarkable water-holding capacity helps to conserve water resources and maintain the anoxic environment of peatlands. 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.

The new species, Lejeunea robbertiana G.E. Lee & Pócs, from New Caledonia is described and illustrated. It is characterized by the abundance of ribbon-like propagules, which are usually 4 cells wide and found on the leaf margins. The leaf cells have well-developed trigones and conspicuous intermediate thickenings, up to 3 per cell. The distantly arranged underleaves with deeply bifid lobes, the pyriform perianth with 5 keels, and autoicy are also the distinguishing characteristics of the new species.

Riccia anguillarum Cargill, is described from Western Australia. This endemic species is distinguished by a fleshy, succulent thallus (similar to southern African species of Riccia in section Spongodes, group ‘Vesiculosa’). It is also unique within Riccia and the Ricciaceae in having a thallus of multilayered air spaces and a bi-layered capsule wall. A description of the new species with images, illustrations and map of its locations is provided.

A Lejeuneaceae updated checklist for São Tomé and Príncipe is presented, including 69 species, being 32 taxa endemic, 23 new records to São Tomé and Príncipe, and 10 new records to Africa. This checklist has been carried out, based on the study of ca. 600 samples housed at LISU herbarium collected by the second author in his postdoctoral project, on two field works in 2007 and 2008, and later in 2016. 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 results corroborate that field work and study of herbarium collections bringing new data for the bryophyte diversity of the archipelago.

We present a peculiar new species in the Grimmiaceae, Schistidium mammillosum, which is distinct in having mammillose leaf cells and pluristratose lamina. 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.
我们介绍了 Grimmiaceae 中的一个奇特新种--Schistidium mammillosum，它具有独特的乳突状叶肉细胞和复叶薄片。这些特征在苔藓中十分罕见，但却为包括同域的 G. alpestris 在内的几个 Grimmia 物种所共有。与此相反，新分类群的孢子体特征表明它是 Schistidium 的一个种，并可能是属间杂交种。核ITS和质体rps4-trnF序列数据一致表明新分类群属于五裂叶草属，从而与杂交起源假说相矛盾。我们认为，乳突状细胞这一共同特征是这两个属为适应相似的环境条件（可能是长期积雪）而独立进化出来的。在形态相似性的支持下，我们的系统发育分析表明，S. mammillosum 和 S. marginale 在 Confertum 支系中是姊妹关系。猛犸角闪孢属（Schistidium mammillosum）定殖于高山和尼瓦尔地区的硅质岩石中，目前已知的产地有法国阿尔卑斯山和瑞士的一个地方。

Fissidens bassilae sp. nov. is described and illustrated from Benin. This terrestrial species is characterized by large cells, persistent protonemata and limbidia restricted to the vaginant laminae of some perichaetial leaves. The similar Asian-Australian F. flabellulus Thwaites & Mitt. var. flabellulus has smaller cells, all leaves elimbate and lacks persistent protonemata. The new species belongs to Fissidens subg. Polypodiopsis.

This represents an update to the 2010 checklist of all hornworts and liverworts reported for Java. The checklist includes i) new information published since 2010, ii) previously overlooked historical literature as well as iii) corrected unintentional mistakes that were published in 2010. We now report that the hornwort and liverwort flora of Java consists of 608 known and accepted species as well as several invalid names that we can not place to any taxon. The updated checklist includes 35 recorded species that are considered dubious and another 157 species are excluded from the flora of Java.

Frullania is one of the largest genera of liverworts in Europe with morphologically polymorphic species in the Holarctic region, giving rise to reservations regarding the delimitation of some taxa. Initially described by Stephani (1887) from Portugal, Frullania calcarifera is a neglected liverwort in the semi-cryptic F. tamarisci complex. Following years of obscurity, F. calcarifera was eventually resurrected as a good species and reported from the Pyrenees, Italy, Algeria and more recently the Ukraine (Crimean Peninsula). In the present study, based on Portuguese material, distinguishing characters and illustrations of the types and representative specimens of F. calcarifera are presented. An updated distribution of F. calcarifera in Portugal, and a predictive model of its known areas of occurrence in Portugal is presented and discussed in relation to the distribution of its congener F. tamarisci.
糠秕属（Frullania）是欧洲最大的肝草属之一，在北冰洋地区有形态多态的物种，因此对一些类群的划分持保留意见。最初由 Stephani（1887 年）在葡萄牙描述的 Frullania calcarifera 是半隐性 F. tamarisci 复合体中一个被忽视的肝草属。在多年默默无闻之后，F. calcarifera 最终作为一个优良品种被重新发现，并在比利牛斯山、意大利、阿尔及利亚以及最近的乌克兰（克里米亚半岛）被报道。本研究以葡萄牙的材料为基础，介绍了 F. calcarifera 的鉴别特征以及模式和代表性标本的插图。本文介绍了 F. calcarifera 在葡萄牙的最新分布情况，以及其在葡萄牙已知分布区域的预测模型，并结合其同属植物 F. tamarisci 的分布情况进行了讨论。
