Tristan da Cunha. — Endemic. On earth or rocks — Moseley. Gathered also by 

 Milne in a very slender state. 



A small and slender species, with its foliage not shrinking away when dry. In colour 

 and look it would seem to be near to Plagiochila terebrans, Nees, Lindenb., t. 20, and 

 Plagiochila pectinata (Willd.), Lindenb. t. 2, but from both it differs in its shorter 

 and wider leaves, which in outline come nearer to those of Plagiochila spinulosa, having 

 the two apical teeth larger and more distinct.
