LONGIPES, D. Don. Near Algarah, с. 6000", 24. iv. (15960, 15961). 
—— QUADRIAURITA, Retz. Gumpahar, с. 7000', 13. iv. (16637). 
—— ASPERICAULIS, Wall, The harsh texture of this fern, and the form of the 
ultimate pinnules, as well as the reddish colour of the young fronds, seem 
to me to distinguish it quite satisfactorily from P. quadriaurita. Algarah, 
с. 6000, 24. iv. (16778, 16779). 
—— ($ CAMPTERIA) BIAURITA, Linn. This is really much nearer quadriaurita than 
aspericaulis is. Below Badantam, с. 2500’, 9. iv. (15995, 15996).

(16638, 16639). 
POLYPODIOIDES, Blume? In the absence of the caudex I am uncertain whether 
this should not be referred to D. multicaudatum, Wall.; it may perhaps be 
D. sikkimense, Clarke. Below Pashok, c. 3000’, 20. iv. (16601, 16602, 16603).

26. iv. (16640, 16641). 
ESCULENTUM, Sw. (Aspidiwm, C. B. Clarke); ex loc. class. and compared with 
Olarke's type, but I suspect Clarke's species to be a mere variation of 
D. maximum. It should be further studied on the spot.  Gumpahar,
