FERNS OF THE CHITRAL RELIF.F EXPEDITION. 125 



measured, 12f in.), bipinnate, glabrous. PinncB about 20 pairs, 

 rarely more or less, distant, subpatent or ascending at an angle of 

 less than 45°, lowest few pairs sometimes widest at one-third from 

 main rachis, others hardly diminished towards base, and with 

 lowest pair of pinnules sometimes elongated ; always acuminate, 

 6-ll| in. long by l^-3f in. broad. Pimudei^ 20 or more pairs on 

 longest pinnfB of large fronds, at the base cut away on the inferior 

 side, and slightly auricled on superior side, %-h in. broad at base ; 

 cut down two-thirds towards costa into G-12 lobes with two or more 

 teeth each, gradually narrowing and sometimes blunt at apex, 

 decurrent on rachis with sometimes a broadly winged base. Texture 

 herbaceous. Colour, when dried, pale olive-green. Veins of pin- 

 nules pinnate, and veinlets forked in the lobes, pinnate in lowest. 

 Sori mostly one on superior veinlet of each lobe, near to or at some 

 distance from costa of pinnule, but more numerous in large lobes, 

 and in lowest lobes of large pinnules ; involucres large, straight, 

 athyroid or hippocrepiform, and sometimes severed at the curve.

A large broad-spreading fern, with a long stipe, and when dried 

 reminding one of Nephrodium ))iar(jinatu)n of Wallich, and me some- 

 times of N. ravwsam. The scales at base of stipe are like those of 

 A. nif/ripes Mett., but pale in colour, as is the frond. The sori do 

 not lie in parallel rows near the costa, like those of A. nicfrijyes, but 

 are generally apart from it, curving outwards, and the involucres 

 are generally much more curved. No doubt specimens of this fern 

 are to be found in herbaria mixed with A. 7iiipipes, but I think they 

 ought to be separated. I erroneously entered it in the Saharunpur 

 Catalogue as A. selenopteris Kunze, but I must now separate them, 

 and I name the species after the brothers Mackinnon, of Mussooree, 

 in whose collection I first saw it, and whose specimens are the 

 lai'gest I have seen, and because they liave largely added to the 

 number of species of ferns found westward of Nepal, and have found 

 several species which are entirely new.
