Inter Dawsoniam polytrichoidem et D. superbam medium 
tenens; a prima longitudine surculi et foliorum atque lamellis creber- 
rimis eorum (cf. Geheeb et Schliephacke in Revue bryologique 1896, 
p. 78) et fructificatione brevius pedicellata jam recedit, a secunda sta- 
tura humiliore foliisque appressis brevioribus angustioribus primo visu 
differt. Planta mascula ut in Polytricho terminalis discoidea saepius 
prolificans.

altus vel ultra robustus angulatus usque ad altitudinem ca. 15 cm 
nudus simplex; folia caulina longissima robusta laxissime disposita 
patula, e basi brevi vaginata aurea in laminam 2—3 cm longam 
angustam planam breviter subulatam subflaccidam dense lamellosam 
producta, e medio dentibus parvis rubiginosis acutiusculis remotis 
simpliciter vel duplicato-dentata ad subulam dentibus densius serrata, 
nervo laminam fere totam replente percursa, e cellulis ad vaginam 
angustissimis densis longis, ad basin laminae maxime incrassatis
