rupestral, with ribbed capsules exserted on a more or less elo ngate seta. 
Peristome orthotrichoid — often, however, imperfect or wanting — 
cucullate calyptra. The species are difficult to define not so much fro 
tendency to intergrade or because they are very variable, but because "the 
differences are slight, and in some cases rest principally on inflorescence 
and on minute peristome differences. In the following key Ihave epg 
quite artifically, to distinguish them, but it is a genus in which a know- 
ledge of the plants themselves is much the safest and easiest guide to their | 
recognition. 
There has been a good deal of confusion caused by duplication of 
specific names in this genus, which it may be of advantage to clear up at 
the commencement.

On turing to Z. submucronatus, however, no such name is found. a | 
explanation probably is that Paris considered the name mucronatus C. 
as ers being antedated by Z. mucronatus Broth., and proposed er it 
the name Z. submucronatus Par., pick: however, slipped out from the 
later ae. The Sdantifieatind of Z. mucronatus C. M., however, with 
Z. anomalus Doz. & Molk. renders Paris’s proposed name unnecessary.
