124 FERNS OF THE CHITRA.L RELIEF EXPEDITION. 



N.W. India from luimauu to the JJehra Dun District, but I find no 

 record of it fartlier westward. L. japonkum Sw. is rarer iu N.W. 

 India, but has been got in the Himalaya and below it from Kumaun 

 westward to the Kangra Valley District, Chamba, and the west of 

 Kashmir, at altitudes of 2300-7000 ft. I have seen no pinnte of 

 either of those species cut at all like those of L. microphijHum, 

 which C. B. Clarke considers the best marked and least variable 

 species of the genus. General Gatacre's plant was got in about 

 35° 25' N. lat. and 71° 60' E. long, at the altitude of 5000 ft. Mr. 

 Gamble, having compared it with the other species, thinks I am 

 right, for, as he says, it certainly comes nearest to L. jnicrophyltum 

 (= L. scandens Bedd.) ; but he has found it in N. Bengal and 

 B. India only iu swampy places, and says it is an interesting 

 problem in geographical distribution how the above-named two 

 tropical ferns got to the Ohitral region.
