Bkown. — 0)1 Neiv Zealand Musci. 443 



Zealand the genus is a small one. The first species of it 

 discovered is recorded in the " Handbook of the New Zea- 

 land Flora," at page 437, as M. longiseta, which is a South 

 American species. It was subsequently found ou examina- 

 tion by Mr. Mitten that it differed from that plant. He has 

 described it and named it M. tenuiseta at page 750 of the 

 Handbook. 



I have seen no specimens of the above-mentioned plant, 

 nor of the one recorded as M. eckloni in a paper read by Mr. 

 Beckett, and published in the " Transactions and Proceed- 

 ings of the New Zealand Institute," vol. xxix., page 443. I 

 have carefully compared the descriptions of M. tenuiseta and 

 M. ecMoni with the new species of this paper, and find the 

 latter quite distinct from either of the above-named species. 

 In the figures of M. huchanani the plant is one-half the mag- 

 nification of the capsule and leaves.

Genus Leptobryum, Wils. 

 This is a small genus of annual mosses, having the same 

 generic characters as the genus Bryum, their annual habit 

 being the principal distinction. Two species of this genus occur 

 in New Zealand — L. pyriforme, Wils., Plate XXXVIII., fig. 11, 

 which is found in most countries, and L. harriottii, of this 

 paper, which is a smaller plant than L. pyriforme, but quite
