i24 FERNS OF THE CHITRAL RELIEF EXPEDITION. N.W. India from Kumaun to the Dehra Dun District, but I find no record of it farther westward. L. japonicum Sw. is rarer in 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 pinnae of either of those species cut at all like those of L. mici^ophyllumj which C. B. Clarke considers the best marked and least variable species of the genus. General Gatacre's plant was got in about 85° 25' N. lat. and 71° 50' 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. microphyllum (= L. scandens Bedd.) ; but he has found it in N. Bengal and B. India only in swampy places, and says it is an interesting problem in geographical distribution how the above-named two tropical ferns got to the Chitral region. Cystopteris fragilis Bernh. Many stations, 4500-11,000 ft., Harriss; Mirga Hills, 8000 ft., Gatacre. Adiantum Capil his- Veneris L. 5 stations, 6000-8500 ft., Harriss; 3 stations, 4000-6000 ft., Gatacre. A. vetiustum Don. Dir, 5000 ft., Janbatai, Harriss; Mirga, 8000 ft., Gatacre. Cheilanthes fragrans Webb & Berth. 4 stations, 4500 ft., Harriss; 2 stations, 4000-5000 ft., Gatacre. 0. Szovitzii Fisch. & Meyer. Chitral, Darosh to Gurait, 4500 ft., Harriss. Pellcea nitidula Baker. Swat State, Laram Pass, 7000 ft., Gatacre. Fteris longifolia L. Dir, 6500 ft., Harriss; below Laram Pass, 4000 ft., Mirga Hills, 8000 ft., Gatacre. P. cretica L. Dir, 6500 ft., Harriss; below Laram Pass, 4000 ft., Darosa, 5000 ft., Gatacre. P. aquilina L. Mirga, Harriss; Gujar Valley, 7000 ft., Gatacre. P. ludens Wall. Ziarat Valley, 8000 ft., Gatacre. Asplenium alternans Wall. Dir, 5400 ft., Darosh to Gurait (or Guirat), 4500 ft., Harriss; below Laram Pass, 4000 ft., Gatacre. A. viride Huds. Lowari Pass, 11,000 ft., Harriss. A. Trichomanes L. 4 stations, 4000-8000 ft., Harriss; Mirga Forest, 9500 ft., Gatacre. A. septentrionale Hoffm. Ziarat, 7200 ft., Harriss; Mirga Forest, 9500 ft., Gatacre. A. Adiantum-nigrum L. 3 stations, 6000-7800 ft., Harriss; Panjkora Valley, 4000 ft., Gatacre. A. fontanum Bernh. Mirga, 8000 ft., Gatacre. A. Mackinnoni, n. sp. Rhizome quasi-erect, clothed, as is also the base of the stipe, with bright castaneous filiform scales. Stipes tufted, straw-coloured or pale brown, glabrous except near the base, or with a few scattered scales for some inches upwards, 8-20 in. loijg. Frond subdeltoid or almost rhomboidal (lowest pair of pinnae slightly shorter than next pair above), 13-23 in. long (average of sixteen measured, 18i in.) by 8-18 in. broad (average of twenty
