Isles on the western side of the island. Another prolific locality 

 is on the property of Mr. Traill, Waterfall Eun, at the head of 

 the inlet, where a considerable portion of the vegetation is 

 made up of these small plants, especially near the water. 



I have found great difficulty in arriving at the determina- 

 tion of the different plants of this genus from the want of 

 sufficiently-identified species, and also from the extreme 

 paucity of the descriptions of some of the Ca^ninjlopi described 

 in the "Handbook of the New Zealand Flora," where Sir W. 

 Hooker remarks " that the New Zealand species are far from 

 being satisfactorily determined, owing to the want of good 

 specimens, and the different views of authors." 



Since that time very little has been done to improve this 

 very unsatisfactory position — in fact, I am only aware of 

 one species having been added to the list — viz., C. hirhii. I 

 have, unfortunately, only a very small barren piece of this 

 moss, which I received from Mr. Kirk himself, so I am even 

 unable to satisfactorily identify the plant. 



I have given figures of all the species of this genus which 

 have come under my notice with the exception of G. hirhii, 

 which has already been figured by Mr. Beckett in vol. xxvi., 

 " Transactions and Proceedings of the New Zealand Insti- 

 tute." The leaves of the different mosses that I have drawn 

 are taken from the same parts of each plant of this very 

 difficult genus. The figures are also drawn to one scale for 

 facility of comparison, &c. 



1. C. introflexus, Hedwig, Handbk. N.Z. Fl., p. 414. 



An extremely common plant in New Zealand, and has a 

 large number of varieties, some of them differing so much in 

 appearance and in the size of the capsule that there is often 

 great difficulty in identification. 



2. G. appressifolius, Mitten, Handbk. N.Z. FL, p. 414. 



I have been unable to identify this plant. This may have 

 resulted from the great similarity existing in the leaves of a 

 great many different species of this genus. This is accentuated 

 by the unfortunate fact that the capsule of this moss is not de- 

 scribed in the " Handbook of the New Zealand Flora," which 

 is apparently the only authority on this matter. It is a matter 

 for regret that descriptions are not always accompanied with 

 authentic drawings, as a considerable amount of time and 

 labour would be saved. My own impression, from reading the 

 remarks attached to the description of C. clavatus, Brown, in 

 the above-mentioned work, is that G. appressifolius is inter- 

 mediate between G. clavatus and G. introflexus, and may 

 possibly be one of the many varieties of G. introflexus.
