ABSTRACT

Hennediella Paris is a globally distributed genus comprising 15 species, of which two are presently known from southern Africa. Field studies in the Cape winter-rainfall area yielded a specimen that could not be assigned to any of the known species of the genus and is here described as new.

Specimens collected using standard bryological field techniques were rehydrated in the laboratory, dissected, and mounted in Hoyer’s solution. Observations and measurements were made using standard stereo and compound microscopy.

Hennediella austroafricana Hedd. & M.J.Cano is a new species that is currently known only from the type locality in the Cape winter-rainfall region at Drie Kuilen, where it grew in Matjiesfontein Renosterveld. It is distinct from all other members of the genus in the combination of leaves with a border of short-rectangular, thick-walled, smooth (or at least less papillose) cells, and sporophytes with a thick seta, and a peristome with a high basal membrane and relatively short, straight to slightly twisted, filiform teeth.

摘要

Hennediella Paris 是一个全球分布的属，包括 15 个物种，其中两个目前已知来自南部非洲。在开普敦冬季降雨区进行的实地研究产生了一个标本，该标本无法归类为该属的任何已知物种，此处将其描述为新标本。

使用标准苔藓学现场技术收集的标本在实验室中再水化、解剖并安装在霍耶氏溶液中。使用标准立体和复合显微镜进行观察和测量。

Hennediella austroafricana赫德。& MJCano 是一个新物种，目前仅在位于 Drie Kuilen 的开普敦冬季降雨区的模式产地发现，它生长在 Matjiesfontein Renosterveld。它与该属的所有其他成员的不同之处在于，叶子的组合具有短矩形、厚壁、光滑（或至少较少具乳突）的细胞边缘，孢子体具有厚刚毛，唇具有高基膜又比较短，直到微扭曲，丝状齿。
