A fine species, distinct in the form and size of the capsule, the 
excessively long perichaetia, and the markedly short upper cells. The 
leaves, more enrolled from near the base, give the plant a distinct appearance 
when dry from that of D. robustwm and others of the broader-leaved species. 
In Petrie’s plant from Kelly’s Creek the capsules, while of the same 
form, are much shorter than in the type; in the Mount Cargill specimen, 
on the other hand, ct are equally large, with an elegantly decurved lid 
almost as long. The in this specimen are slightly longer and the 
ee slightly mare fei in the type, so that the seta is about half 
serted.
