This moss is very common throughout the Antarctic regions. The specimens from Hermite Island have the 
leaves more obscurely toothed than British examples, and the branches very short. It may be R. Borbonicum,

Both these varieties differ from the Campbell’s Island state of the moss.

It will be seen how closely the description corresponds with that of O. coarctatum, Br. and Schimp.; but on 
comparing authentic specimens, we find the leaves in the latter much wider and carinate, less dilated at the 
base, more crisped when dry, the vaginula twice as long, capsule larger, and the habit considerably different. 
Our moss, unlike that, has very little resemblance to O. crispum, and is remarkable for its pale yellowish colour ; 
it varies in the length of the seta. An original specimen of O. coarctatum (from P. de Beauvois in Professor Arnott’s
