168 BRYOLOGY OF NEW ZEALAND. 
his introductory remarks he admits that though he has been unable to 
identify any of his plants with already described species, it is possible that 
some of them may be identical, but he has ‘“‘ therefore treated the whole of 
the plants collecte y me as new species, with the exception of 
O. graphiomitrium.” Unfortunately, partly owing to the adequacy of the 
tim 
represented by his descriptions. Happily his herbarium contains thirty- 
six out of the forty described species, and in the case of the missing species 
the descriptions and figures afford sufficient evidence to enable them all to 
be recognized without doubt as identical with one or other of the already 
described species. The four species described in the Trans. N.Z. Ins 
vol. 35, pp. 332-3, are unrepresented in Brown’s herbarium, but 
fortunately in three cases the descriptions leave practically no doubt, and 
in the fourth very little, of their identity with already published species. 
R. Brown based his arrangement upon two characters—the presence or 
e 
plants as with “ / Sage nage ” owing to the destruction through age of 
the inner proces 
His notes on the Nicrtbutidn and ecology of the genus are interesting 
and valuable. 
The result of my examination of Brown’s Agee is that. the forty- 
four species described as new must be reduced to eight. these, five 
had already been published under other names, eave the remaining three 
names to stand; two of these three are published under more 
name by Brown, and in these cases I have taken the earliest — 
These three names are— 
O. cyathiforme R. Br. ter. =O. pseudo-pumilum Vent. 
O. pulvinatum R. Br. ter. = O. thd Soper Vent. 
O. lancifolium R. Br. ter. =O. rufidens Vent. ined.
