THE FERNS OF NORTH-WESTERN INDIA, 
283 
In Chamba McDonell never got a fertile frond of 0. regal is. In J; osar and 
British Garhwal specimens the fertile and steri'e fronds are quite separate* 
Duthie and Gamble got both kinds of fronds on the same date, in May. Duthie’s 
specimens from PaGhmarhi* in the Central Provinces, India, and Gamble's from 
the Madras Presidency, are typical 0. regalis , but small.

The only materia] from the Trans-Indus States consists of a part of a frond 
with only sterile pinnae, the shape of which agrees with those of L. microphyl- 
lum , and they are unlike those of the other species of Lygodium which have 
been found in N.-W. India, Mr. Clarke considers L. microphyllum the best 
marked and least variable species -of the genus. It has not before been found 
in N. India west of Bhotan, Assam, and the plain of N. Bengal. General 
Gatacre’s plant was got in about N. Lat. 35 0 -25', and E. Long. 71°-50 / , 
Mr. Gamble agrees with me in the identification of this specimen, and says it is 
an interesting problem in geographical distribution — how this and Pier is 
ludens (see supra Vol. XIII, No. 3, p, 457), got into the Chitral Region.

This fern is common in the Debra Dun. The fronds from the same root 
twine together, and if there is a small tree within reach together twine round 
its trunk to a considerable height. I have measured a plant trailing on the 
ground, which was 12 ft. in length. The.rhizome is small, erect or suberect : 
stipes approximate, wiry, covered at base with minute black-brown scales ;
