Supplementary remarks:
[in litt]
I spent a little time looking at the Arrowtown Tortula. It is amazing how similar this plant is to T. petriei. Except that the cells are smooth, the border narrower & the plant smaller in all its parts, it might well be taken for this species. Even the porose rectangular cells of the midleaf are present in T. petriei (which I observed in some old leaves with a few cells without chloroplasts. Naturally the porose cells wall is difficult to observe because of the papillae but quite definite)
Doubtless you will have noticed that the base of the seta is twisted lightly to the right & the top tightly to the left (using Dixons terminology.) This also is the case in T. petrei, T. rubra & T. serrulata but not so in T. bealyensis, T. principes or T. tenella specimens in my (rather limited) collection.
Like T. petriei the plant is autoicous & has large spores, perhaps bigger than T. petriei which species has the biggest spores of any N.Z. Tortula. I notice Dixon (p. 144 Studies) states T. denticulata (Wils.) Mitt. of S. AMerica is similar & has pellucid cells. It would be interesting to get this description.
