ME. W. mitten's list OF SAMOAN MOSSES. 191 



Branches a foot long ; sometimes they are even a foot and a 

 half, the lateral branchlets rarely exceeding an inch in length. 

 Leaves green and shining. 



This fine moss comes near to the Hypnum dxiplicatuin^ Schw, 

 t. 279 ; but its leaves are more widely auriculate, and the peri- 

 chaetial leaves more closely convolute ; with a few other species 

 found in India and the Indian archipelago, it forms a small group 

 having at first sight so much the appearance of the larger species 

 of Nechera as to be easily confounded with them,

In size similar to D. adnatum^ H. f. et W., of New Zealand, 

 but less compressed and of a yellow colour. The leaves are not 

 perceptibly different in size and form on the uppcrside, as is so 

 generally the case in the allied species. In habit it appears to 

 correspond with D. BicJcsoni, H. f et W. {Ilookeria).
