Orthotrichum revolutum(Orthotrichaceae,Bryophyta),an Endemic Species to China,Rediscovered after 123 Years

卷叶木灵藓(Orthotrichum revolutum)是一种中国特有藓类植物,自从123年前的首次采集之后再也没有被发现过。本文增加了一个新地点,即北京百花山自然保护区。这份标本在形态上与模式十分一致。本文第一次提供了卷叶木灵藓的详细的形态照片和地理分布图。四个来自中国甘肃、新疆以及境外日本和吉尔吉斯斯坦的记录都被证实是错误鉴定。我们还讨论了该种和邻近种的区别,以及野外濒危等级的重新评估。

Orthotrichum revolutum,an endemic to China,has not been re-found since its original collection made 123 years ago.It is recorded from a new locality:Baihuashan Nature Reserve,Beijing,China.The plants morphologically agree well with the type specimens.Orthotrichum revolutum is firstly well photoed and its distribution is firstly mapped.Four records of this species from China’s Gansu,Xinjiang and Japan,Kyrgyzstan are all misidentifications in previous studies.We also discuss its main differences from close species and reevaluate its threat status in the field.
