Notes on the fern family Tectariaceae from Hainan Island,China

Ataxipteris dianguiensis W. M. Chu & H. G. Zhou and Tectaria polymorpha (Wall. ex Hook.) Copel. are reported as new records to Hainan Island, China; T. polymorpha var. subcuneata Ching & Chu H. Wang is reduced to synonymy of T. polymorpha (Wall. ex Hook.) Copel. The morphological variation of T. subtriphylla (Hook. & Arn.) Copel. and the differences between T. simonsii (Baker) Ching and T. media Ching are discussed. A lecototype is designated for A. dianguiensis. Up to date, 20 species of 8 genera in Tectariaceae are recorded to occur in Hainan Island.     

Foonchewia guangdongensis gen. et sp. nov. (Rubioideae: Rubiaceae) and its systematic position inferred from chloroplast sequences and morphology

Abstract The new species, Foonchewia guangdongensis R. J. Wang & H. Z. Wen and the new monotypic genus Foonchewia R. J. Wang (Rubioideae, Rubiaceae), are described from eastern Guangdong, China. It is characterized by its subshrub habit, pentamerous and heterostylous flowers, 2‐1ocular ovary with many ovules, and apically dehiscent capsules with numerous angulated seeds. Phylogenetic analysis of four chloroplast DNA regions (rbcL, rps16, ndhF, and atpB‐rbcL) revealed that the new genus is nested in the Spermacoceae alliance and is sister to Dunnia. Morphological comparison between these two genera indicated that they had few synapomorphies; it was therefore inappropriate to classify the new genus in the existing tribe Dunnieae, and a new tribe, Foonchewieae R. J. Wang, is accordingly proposed.

Observations on Hookeriales,I. The taxonomic status of African species of Sauloma (Hook. f. & Wils.) Mitt. (Hookeriales)

African members of the moss genus Sauloma (Hook. f. & Wils.) Mitt are evaluated. Sauloma tisserantii P. Varde from Oubangui, Sauloma humblotii (Ren. & Card.) Card. (= Lepidopilum humblotii Ren. & Card.) from the Comoros and S. africana Dix. & Thér. from Central Africa are all conspecific with Leucomium strumosum (Hornsch.) Mitt. (Hookeriales, Leucomiaceae), the first two names being synonymized with the latter for the first time. S. julacea C. Müll. in Par. nom. nud. correctly belongs within Meiothecium (Sematophyllaceae) and S. chloroclada C. Müll. in Broth. nom. nud. is Meiothecium chlorocladum (Broth.) Broth. Accordingly, the genus Sauloma has to be excluded from the bryoflora of mainland Africa and adjacent islands.

Zander, but differs in plants growing loosely in a thin turf, stems without hyalodermis and sclerodermis, margins recurved from just above the base nearly to the apex, laminal cells strongly bulging, mammillose, covered with simple or forked papillae, and costa with a layer of ventral substereids. The new species is contrasted with other similar species of the genus. Information on its distribution and ecology is also provided.

算盘子属(Glochidion J.R.G.Forst.)是叶下珠科(Phyllanthaceae)叶下珠族(Phyllantheae)中一个分类极为困难的类群。基于广泛野外考察与馆藏标本查阅,对中国该属部分物种进行分类学处理。其中,长柱算盘子[G.khasicum(Müll.Arg.)Hook.f.]与倒卵叶算盘子(G.obovatum SieboldZucc.)在中国的分布予以排除,菲岛算盘子[G.philippicum(Cav.)C.B.Rob.]在中国被发现仅分布于台湾地区;G.bodinieri H.Lév.,G.pseudo-obscurum var.glabrum Pamp.与G.pseudo-obscurum var.lanceolatum Pamp.这三个名称被处理为湖北算盘子(G.wilsonii Hutch.)的新异名;G.vaniotii H.Lév.被排除在算盘子属外,并接受为芸香科臭常春(Orixa japonica Thunb.)的异名。另外,对G.khasicum(Müll.Arg.)Hook.f.,G.obovatum SieboldZucc.,G.philippicum(Cav.)C.B.Rob.,G.pseudo-obscurum var.lanceolatum Pamp.及G.wilsonii Hutch.这五个名称进行了后选模式的指定。
