about 3/8 to 7/16 in. apart, rarely h in. or over, and the segments suddenly taper 

 at about two-thirds of their length. The fronds of lachnopus are much weaker 

 and thinner than those of amcenum, and they hang perpendicularly from the 

 trees they grow on. I have rarely seen P. lachnopus on rocks. P. amcenum 

 generally, I think, grows on rocks, or in soil on rocky slopes, sometimes stand- 

 ing upright ; but in Mussooree I have seen it on trees. When in a young state 

 the fronds are very pubescent, and always there are numerous small chaffy 

 scales on and near the rhachis on the under side. The fronds of P. lachnopus 

 are all but naked.

See my remarks under P. amcenum, Wall., No. 14, above. Occasionally, when 

 growing in an exposed dry situation I suppose, this fern is very small and wiry : 

 Duthie's example from the Jumna Valley has fronds only 4"XH" 1. including 

 Btipes. MacLeod's, from the Kala Muni Ridge, Kumaun, is from 6 to 11 in. 

 including stipes. I watched this fern at Mussooree for a number of years, and 

 I believed it was spreading there. It is a striking object, hanging from the 

 large oak trees in the forest, on the north side of the ridge, up to 6500' alt., and 

 I could easily distinguish it from P. microrhizoma, Clarke (which is much more 

 common) at some distance. The elevation — " up to 11,000' " — given in the 

 Synopsis, seems much too high, and Clarke's higher limit, G000', is too low ; 

 but Beddome has cut that down to 3000', on what authority I know not. 

 Blanford says — *' Not very common at Simla. Found on trees and rocks in 

 shady ravines below 6000'."
