摘要

摘要在印度喀拉拉邦Kozhikode和Malappuram地区受干扰的低地地区，描述了Riccia的一个新种，R.keralensis sp.nov。Riccia keralensis类似于Squamatae组中的物种，例如R.billardieri Mont&Nees。，R.gangtica Ahmad前L.Soderstr.和R.treubiana Stephen。铊的外观和内部结构不同，但孢子明显不同，几乎所有孢子都有明显的三辐射标记，翅膀突出，直径上的小晕较少。keralensis Riccia在其外部铊形态、单体性、孢子中乳晕的形式和数量方面也与Ricciella亚属的R.pandi Udar和Spongodes和Crystallina组相似，直径为5-6。但它与R.pandi Udar在铊的内部解剖结构、孢子大小和孢子光滑的蛭石质地方面有所不同。

A new species of Riccia (Ricciaceae: Marchantiophyta) from the Western Ghats of Kerala

Abstract. A new species of Riccia, R. keralensis sp. nov. of the subgenus Riccia of section Riccia and group Squamatae is described from the disturbed low land areas of Kozhikode and Malappuram districts of Kerala, India. Riccia keralensis resembles species in the group Squamatae such as R. billardieri Mont & Nees., R. gangetica Ahmad ex L.Soderstr. and R. treubiana Steph. in external appearance and internal structure of the thallus, but distinctly differs in the spores which have a distinct triradiate mark in almost all spores, prominent wing and fewer areolae across the diameter. Riccia keralensis is also similar to R. pandei Udar of the subgenus Ricciella and section Spongodes and group Crystallina in its external thallus morphology, monoicous sexuality and form and number of areolae in the spores, which are 5–6 across diameter. But it differs from R. pandei Udar in the internal anatomy of thallus, the spore size and the smooth-vermiculose texture of the spores.

期刊介绍： The Bryologist is an international journal devoted to all aspects of bryology and lichenology, and we welcome reviews, research papers and short communications from all members of American Bryological and Lichenological Society (ABLS). We also publish lists of current literature, book reviews and news items about members and event. All back issues of the journal are maintained electronically. The first issue of The Bryologist was published in 1898, with the formation of the Society. Author instructions are available from the journal website and the manuscript submission site, each of which is listed at the ABLS.org website. All submissions to the journal are subject to at least two peer reviews, and both the reviews and the identities of reviewers are treated confidentially. Reviewers are asked to acknowledge possible conflicts of interest and to provide strictly objective assessments of the suitability and scholarly merit of the submissions under review.
