桃儿七属的命名学考订

桃儿七属（Sinopodophyllum）是中国-喜马拉雅地区特有的单型属,仅桃儿七（Shexandrum）一种。桃儿七的根茎和果实均具有较高的药用价值,人类的过度采挖和种群恢复较慢使其种群数量急剧下降,现已被列入《中国物种红色名录》。在近年来的一些研究论文中,学名Shexandrum和Semodi常被混用,这使得有必要考证桃儿七学名的命名学历史,确认正确的学名使用。查阅原始文献发现,Shexandrum的基名Podophyllum hexandrum Royle发表于1834年,而Semodi的基名Podophyllum emodi Wall. ex Honigberger到1852年才合格发表（大多数学者认为是Hooker和Thomson在1855年合格发表）,因此,名称Shexandrum比名称Semodi具有优先权。名称的混乱起于1979年应俊生建立桃儿七属时,他提出组合“Semodi (Wall.) Ying”作为桃儿七的学名。另外,由于他未引证Honigberger或Hooker和Thomson的文献信息,所以组合“Semodi”没有被合格发表（规则415）。随后,1985年出版的《西藏植物志》桃儿七属中,应俊生发现之前的错误并采用名称“Shexandrum”取代了“Semodi”。遗憾的是他虽然意识到该名称是新组合,但未引证基名Phexandrum合格发表的文献信息,使得组合“Shexandrum (Rolye) Ying”没有被合格发表。近年来出版的《云南植物志》、《青海植物志》、《中国植物》和《Flora of China》均未发现该错误,一直认为“Shexandrum (Rolye) Ying”合格发表时间是1985。实际上,在1993年由于编写格式要求,应俊生在王文采和武素功主编的《横断山区维管束植物》中引证了基名合格发表的文献信息。因此,该名称的合格发表时间是1993年,而不是常认为的1985年。     

Petrocosmea glabristoma (Gesneriaceae), a New Species from Yunnan,China

Petrocosmea glabrstoma ZJ. Qiu & YZ. Wang, a new species from Yunnan Province, China, is described and illustrated. The new species is similar to Petrocosmea forrestii Craib and Pmairei Lévl., but differs from them mainly by its leaves triangular or triangular ovate, corolla glabrous inside with shorter filament. Molecular and morphological data demonstrate that this new species has a close affinity to Pforrestii.     

Tremacron hongheense,a New Species of Gesneriaceaefrom Southeastern Yunnan,China

A new species of Gesneriaceae from Honghe County, Southeastern Yunnan, China, Tremacron hongheense WH. Chen & YM. Shui, is described and illustrated. The new species is similar to Tremacron forrestii Craib, but differs by its leaf blade adaxially sparsely long setose (vs. densely white appressed pubescent and sparsely rusty brown villous), corolla tube outside short white glandular (vs. nearly glabrous), corolla lobes red and thickening at apex, especially adaxial lip (vs. yellow and not thickening), stamens 16-18cm long (vs. 04-12cm long), staminode 05-14cm long (vs. 02-04cm long).     

New Distributional Records of Two Monotypic Moss Genera Arthrocormus and Noguchiodendron in China

Two monotypic genera, Arthrocormus Dozy & Molk. and Noguchiodendron TN. Ninh & Pócs are reported as new distributional records for China. Arthrocormus schimperi is widely distributed in tropical Asia and Oceania, while Nsphaerocarpum is previously reported from Bhutan, India, Nepal and Thailand. Arthrocormus schimperi looks like some Leucobryaceae species and Nsphaerocarpum resembles Homaliodendron spp. We speculate these are the main reasons why they have been overlooked by collectors. The extremely brittle tips with a cylindrical appearance in the upper portion of leaves make Arthrocormus very distinguishable in the field, while the strongly curled branch in dry condition is the most diagnostic feature of Noguchiodendron. Illustrations for both taxa reported are provided for reference purposes.     

New Species of Meconopsis (Papaveraceae) from Mianning,Southwestern Sichuan

Two new species of Meconopsis, Mpulchella and Mheterandra are described and characterized. Differences with similar species are discussed and photos showing the diagnostic features are provided.     

Raphiocarpus jinpingensis,a New Species of Gesneriaceae in Yunnan,China

Raphiocarpus jinpingensis WH. Chen & YM. Shui, a new species of Gesneriaceae, is described and illustrated, from the Xilong Mountain of Jinping County in Yunnan, China, bordering to North Vietnam. The new species is similar as Rpetelotii (Pellegr.) Burtt in shapes of corolla and yellowish flowers, and differs from Rpetelotii mainly in its plants with dense pubescence and calyx tubes subequal to calyx lobes.Its pollen grains and seeds are reported here under Scanning Electonic Microscope (SEM).     

Polystichum mulunense (Dryopteridaceae), a New Species from Karst Caves in Guangxi,China

Polystichum mulunense XL. Shen & RH. Jiang, a new species from karst caves in Guangxi, China, is described and illustrated. This new species is morphologically similar to Polystichum guangxiense and Pfengshanense, but can be easily distinguished from the latter by rhizome scales lanceolate, margins sparsely serrulate and pinnules coriaceous, attached at ca. 60-75 degree angles to rachis and rhomboidal to trapeziform.
