Sphaerocarpales, one of 15 orders in liverworts (Marchantiophyta), is of evolutionary and phylogenetic importance, but has not been recorded in China. Recent expeditions to Hengduan Mountains in China found an interesting liverwort with flask-shaped involucres clearly belonging to Sphaerocarpos, the second largest genus of Sphaerocarpales with nine species. The SEM observations and phylogenetic analyses based on DNA sequences of nuclear ribosomal 26S and two plastid regions (rbcL and psbA-trnH) indicate that the Chinese plant represents a new species described as S. siguniangensis. Our results also reveal that S. texanus known from Africa, America, Europe and Oceania is not monophyletic, suggesting that broader sampling and further analyses of its related species are needed to arrive at a proper understanding of this interesting genus. A new subgenus known only from the U.S.A., Sphaerocarpos subg. Criscarpos, is proposed.

Riccia is the largest genus of complex thalloid liverworts (Marchantiopsida) with over 250 species currently accepted. Our recent investigation of Chinese liverworts found two interesting Riccia species, R. junghuhniana and Riccia subcrinita sp. nov. Riccia junghuhniana is currently known from Australia and Indonesia, while Riccia subcrinita is known only from China. Riccia subcrinita is similar to R. crinita, but differs in having smaller spores (56–71 µm in diameter), and spore distal surface and proximal surface alveoli without thick borders. The sequences of rbcL, rps4, and trnL-F, detailed descriptions, and illustrations of the Chinese specimens are provided. The range extension of R. junghuhniana suggests that more taxa of Riccia may have a wider distribution. The discovery of R. junghuhniana and the new species also suggests that a more intensive survey of Riccia diversity in China is necessary.

Marchantia longii R.L.Zhu, Y.L.Xiang et L.Shu sp. nov. (Marchantiaceae) from northwestern Yunnan, China, is described as new to science. It is similar to Marchantia emarginata, but can be distinguished by the large epidermal pore ((108−)150−210 μm in diameter), the acute to obtuse inner margin of surrounding cells of pores in vertical section, the female receptacle dissected (0.2−0.4 of diameter) into 5−7 subquadrate to oblong lobes truncate or rounded apically, and the entire to weakly dentate margin of the appendage of the median scale. A phylogenetic analysis based on DNA sequences of rbcL, trnL–F and nrITS1–5.8S confirms M. longii as a sister to the clade of M. emarginata subsp. tosana + M. inflexa + M. papillata subsp. grossibarba, and this new species is placed in Marchantia subg. Clamidium.

L'hépatique macaronésienne Riccia boumanii Dirkse, Losada & M.Stech (Marchantiophyta: Ricciaceae) confirmée nouvelle en Asie par des preuves morphologiques et moléculaires. Riccia L. est le plus grand genre d'hépatiques thalloïdes complexes avec plus de 250 espèces actuellement acceptées. Riccia boumanii Dirkse, Losada & M.Stech (Ricciaceae) a été considérée comme endémique des îles Canaries, en Espagne. Des preuves morphologiques et des analyses phylogénétiques moléculaires basées sur les séquences du ribosome nucléaire ITS2, du plastide rbcL, et du plastide trnL-F confirment que cette espèce est présente dans le Gansu et le Sichuan, en Chine. Riccia boumanii représente la première espèce de la section Pilifer Volk du genre en Asie. Les faibles valeurs des p-distances (0 % pour la région trnL-F, et 1.6 % pour la région ITS2) révèlent que R. boumanii présente un faible niveau de divergence. Des micrographies, une carte de distribution et des descriptions basées sur les plantes chinoises sont fournies. L'extension de l'aire de répartition de Riccia boumanii suggère que d'autres taxons de Riccia pourraient avoir une distribution plus large.

Xiang, Y.-L., Xu, H., Shen, C., Huang, W.-Z., Zhang, L.-N., Shu, L. & Zhu, R.-L. 2023. Taxonomische Bemerkungen und Arealerweiterungen von einigen komplex aufgebauten, thallosen Lebermoosen. – Herzogia 36: 193 –205. Riccia billardierei Mont. & Nees und R. rhenana Lorb. ex Müll.Frib. wurden in Südchina nachgewiesen. Phylogenetische Analysen der Gattung Riccia basierend auf den Sequenzen rbcL, rps4 und trnL–F zeigen, dass zwei chinesische Proben von R. billardierei und sechs Proben aus Australien und Thailand eine gut unterstützte Gruppe bilden, die Schwestergruppe zu R. gangetica ist. Riccia rhenana wird erstmals molekular-phylogenetisch untersucht und ist Schwester von R. fluitans L. Sphaerocarpos siguniangensis R.L.Zhu & You L.Xiang wurde erstmals außerhalb der Typuslokalität nachgewiesen. Die bisher nur aus Sichuan bekannte chinesische Exormotheca bischlerae Furuki & Higuchi wurde in Yunnan und Xizang neu gefunden. Außerdem wurden Aitchisoniella himalayensis Kashyap und Peltolepis quadrata (Saut.) Müll.Frib., die in China selten sind, erstmals in Yunnan bzw. auf dem Qinghai-Tibet-Plateau nachgewiesen. Abbildungen werden von Aitchisoniella himalayensis, Exormotheca bischlerae, Peltolepis quadrata, Riccia billardierei, R. rhenana und Sphaerocarpos siguniangensis bereitgestellt.
