"Very closely resembling //. plmncBforme^ Wils., and with it allied to 

 H. Buitenzorgii, Mont., but its leaves are much wider, with no trace of 

 the sinuation just above the base. This Moss is common in the Kha- 

 sia mountains, and seems to be always of a fresh green colour, without 

 a tendency to the golden tint observable in its allies. The branches 

 are three inches long and more, and very much compressed.
