Observations. — I am pleased to have found specimens of this 

 species in the collection as it has given me the opportunity of study- 

 ing the point raised by Dr. Spruce in On Cephalozia, p. 59, 1882. 



Mitten in Hooker's Handbook of the New Zealand Flora, savs of 

 Lemhidium nutans, "the stem is clothed with a vesicular coat." 

 Spruce in a footnote adds, "Mitten attributes 'a loosely cellular coat' 

 to the stem. There is, however, none such and the 'looseness' exists 

 solely in the author's perceptions." 



I know there was no love lost between these two authorities but 

 I think this is the only instance where their loss of love is shown. 



In Lindenberg & Gottsche 's Spec. Hep,, t. 22, is given a cross- 

 section of a stem with an underleaf attached, which shows the stem 

 to be thicker than it is broad. It is not so : it is broader than it is 

 thick. 



I find that the cortical cells are about the same size as the inner, 

 but there is one peculiarity about the stem. At each lateral side, the 

 central cell is usualty larger and prominent, so that when the stem 

 is observed lying flat it appears to have a loose cellular coat — a justi- 

 fication for Mitten's apparent looseness of observation.
