ABSTRACT

Introduction.

Syrrhopodon wallisii Müll.Hal. [≡ Mitthyridium wallisii (Müll.Hal.) H.Rob.], whose primary type material in B was destroyed during the Second World War, is lectotypified from among surviving original material, and its controversial interrelationship with its close relative M. crassum (Broth.) H.Rob. is investigated.

Methods.

Nomenclatural and taxonomic investigation was carried out with reference to bryological literature and herbarium material, including type specimens. It involved the microscopic investigation and analysis of leaf morphology in both historical and recent collections.

Key results and conclusions.

Mitthyridium wallisii is lectotypified with a specimen in the herbarium of E. Hampe (BM000662478). Based on morphological evidence, the Malesian moss taxa M. wallisii and M. crassum are likely to be distinct entities with the status of species.

Mitthyridium wallisii (Müll.Hal.) H.Rob.：选型和与 M. crassum 的相互关系 (Broth.) H.Rob.

摘要

介绍。

Syrrhopodon wallisii Müll.Hal。[≡ Mitthyridium wallisii (Müll.Hal.) H.Rob.]，其 B 中的主要类型材料在第二次世界大战期间被摧毁，是从幸存的原始材料中选出的，其与其近亲 M. crassum 的有争议的相互关系（肉汤。）H.Rob。被调查。

方法。

参考苔藓学文献和植物标本室材料，包括模式标本，进行了命名和分类学调查。它涉及对历史和近期收藏品中叶子形态的显微调查和分析。

主要结果和结论。

Mitthyridium wallisii在 E. Hampe (BM000662478) 的植物标本室中用一个标本进行了选型。根据形态学证据，马来苔藓类群M. wallisii和M. crassum可能是具有物种地位的不同实体。
