This plant has so much the habit of a Hypnum, or rather per- 
haps that of a Leskea, that it was only after an examination of 
various capsules that I was able to satisfy myself that it had but 
a single peristome. The teeth, too, are singularly rigid. Among 
the Pierogonia 1 know of none with which it is at all liable to 
be confounded,
