Type in Herb. C. Miill., in Mus. Bot. Berolin 
A fairly es marked species, with distinct habit; the very long, 
setaceous, flexuose leaves are characteristic, the uppermost gathered into 
a fine, delicate pebitil which at first sight is scarcely paren, ero from 
the young perichaetia. e upper cells separate it at once from D. platy- 
caulon and D. cylindropysis ; the non-tubular subula, the nerve, distinct, 
prominent, and subterete in the subula, but becoming weaker below, 
together with the narrower-walled, distinct upper cells, from D. robustum. 
The shorter, stouter seta, and the scarcely curved estrumose capsule, are 
also, when present, characters of importance. D. chrysodrepaneum most. 
nearly resembles it, but appears to be distinct in the leaves falcato-secund, 
less longly setaceous, ones above and with shorter cells, the denticula- 
tion of the margin and closer, and the nerve stouter at base. 
Renauld gives a: ‘peti as exhibiting the Toxoneuron type of nerve. 
It appears tom me Ss (as in D. setosum) intermediate between that and

This seems to m a fairly good species, though nearly allied to D. 
grossialare and nal more closely to D. robustum. The leaves are dis- 
tinctly less longly setaceous than in the former species, and with the

The seta may be a shade less ‘stout, but in other respects the fruiting
