ABSTRACT Introduction. During an investigation into the world-wide distribution of Anthoceros caucasicus Steph., we examined a voucher collected from Sierra Leone by A. J. Harrington in 1966 and subsequently studied by E. W. Jones. Methods. Based on spore observations using light and scanning electron microscopy we found that three Anthocerotophyta taxa were present in this mixed collection. Key results. We report Anthoceros aff. bharadwajii Udar & A.K.Asthana new to Africa, Phaeoceros laevis (L.) Prosk. new to Sierra Leone and tropical Africa, and Anthoceros punctatus L. new to Sierra Leone and western mainland Africa. Conclusions. Anthoceros caucasicus should be removed from the Sierra Leone bryoflora list, and possibly from tropical Africa.

摘要介绍。在对 Anhoceros caucasicus Steph. 的全球分布进行调查期间，我们检查了 AJ Harrington 于 1966 年从塞拉利昂收集并随后由 EW Jones 研究的凭证。方法。基于使用光学和扫描电子显微镜的孢子观察，我们发现在这个混合集合中存在三个 Anhocerotophyta 分类群。关键结果。我们报告Anhoceros aff。bharadwajii Udar & AKAsthana 新到非洲，Phaeoceros laevis (L.) Prosk。塞拉利昂和热带非洲的新物种，以及塞拉利昂和非洲西部大陆的新物种 Anhoceros punctatus L.。结论。Anthoceros caucasicus 应该从塞拉利昂苔藓植物名单中删除，并可能从热带非洲中删除。
