304 Mr. Menzies'j Account of a Species of Polytrichum. 



This fpecies was found araongft the duplicates of Mr. Nelfon's 

 collection of plants from New Zeeland, in Sir Jofeph Banks's 

 Herbarium; and as it agrees fo nearly with P. rubeHum, perhaps the 

 beft manner of defcribing it is to point out the difference. 



Thzftalk of this is flightiy branched, and in general taller than 

 P. rubellum. The leaves are larger and more acutely lanceolate, with 

 whitifh edges finely ferrated, and middle nerves ftrongly dentated ; 

 their texture is more tender and fragile; their colour in the dried 

 ftate is the fame, but whether they are reddilh, like the others, in 

 their recent ftate, is uncertain ; they are more crowded at the tops 

 and about the divifions of the branches. The peduncles in general 

 are at leaft half an inch longer, and terminate both the upper and 

 lower branches; but the moft remarkable difference is in the 

 operculum being long and fubulate, whilft. in the other it is flat, 

 with a fmall point iffuing from its centre. The capfule y in this, is 

 longer and more (lender, and the exterior calyptra is of a fujmlate 

 fhape, whilft in the other it is of a conical figure.
