A relative of the African species described by Brotherus as Bryum perspinidens, has been discovered in Guyana with erect capsules and a short inner peristome. The Guyana material is recognized as a new species, and both species are placed in the genus Brachymenium. The characteristics that distinquish the genus are discussed with reference to the Guyana specimens of Brachymenium speciosum.

圭亚那的Brachymenium记录以及来自Mt. 阿扬安娜

在圭亚那发现了一种由Brotherus形容为Bryum perspinidens的非洲物种的亲戚，它有直立的胶囊和较短的内部Peristome。圭亚那材料被认为是一种新物种，并且两个物种都被置于短命属中。区分属的特征将参照近岸短臂圭亚那的圭亚那标本进行讨论。
