Mr. Clarke can distinguish this fem from some large specimens of P. lachnopus 
Wall. (No. 15 below) only by the scales (on rhizome ? ) not being hair-pointed : 
he says there is no difference between the two, and he has P. lachnopus exceed- 
ingly large. One does not need to look at the scales to distinguish between the 
two species. P. amcenum has a broadly lanceolate frond— -twice to thrice, 
rarely more— as long as it is broad : P. lachnomis is linear-lanceolate, commonly 
six to seven times as long as broad, and rarely is the breadth so much as 
one-fifth of the length : 15in. 1. by 2in. broad are common dimensions, and I 
have a frond 21 in. by 3 in. The number of pinnae (or lobes) in the two 
species is considerably different : in amcenum it is sometimes less than 20, gene- 
rally 25-30, and very rarely reaching 25-40 • in lachnopus the number is rarely 
below 30, and frequently reaches 45 or morel In amcenum the costae of the 
segments are from | in. to ]| in, apart, and the segments gradually taper from 
a .broad base to a generally very fine point : in lachnopus the costae are generally
