Baker, Clarke, and Beddome all say this species differs from P. quadriaurita 
only in the venation ; but I must maintain that, apart from the difference in 
venation, the two species are abundantly unlike, and that no one knowing 
the two in growth, in N.-W. India at least, could ever mistake the one for the 
other. The form P. nemoralis, Willd., or a form which has both free and 
inarched venation on the same frond, is got in the Dehra Dain; and I have 
one small plant, less than 18 inches in height, altogether without inarched 
venation, but with forked veins, springing from the rhachis between the seg- 
ments, which sometimes unite with the lowest costal veins. A large plant from 
the Dun has stipes 26 in., and frond 34 in, in length. These are 143 pairs of 
pinne, of which the lowest pair is over 12 in. 1. by almost 3 in. br.: these 
are bipartite, the secondary pinne being 10 in, 1. The terminal pinna is 
nearly 9 in. by 14 in. The lowest pinnee of P. biaurita are, I should say, 
always bipartite ; but I have never seen more than one descending pinnule or 
ear on each side : Clarke says there are sometimes two or three. 
From Selim, below Darjiling, at altitudes of 1,200 and 1,500 feet, respective- 
ly, Gamble has two very different-looking plants, both of which he names 
P. biaurita, and both of which are Campteria : one has dark-coloured rhachises, 
8-10 pairs of pinne, and broad, blunt, approximate segments: the other is 
much paler in colour, with straw-coloured rhachises, 8-15 pairs of pinne, with 
long narrow far-apart segments. This latter is what is supposed to be P. nemo- 
valis, Willd., as the veins of contiguous segments often miss connection below 
the sinus ; but it is quite different in cutting, colour, and appearance from my 
Dehra Dim specimens above described : the venation only is similar.
