FLORA OF THE SUNDRIBUNS. 
P. ample xicaulis (P. longifolia Linn>)\ stipes in tufts, and short ;when old 
scabrous ; when young, woolly : pinnae with enlarged stipe-clasping 
bases, rather obtusely pointed and fertile almost to the very points. 
The other characters may be theoretically assumed to be likely to break down 
in the case of so common and so wide-spread a fern as P. longifolia, but no writer 
on ferns has, so far, claimed that P. longifolia ever has an elongated, stout, creep- 
ing rootstock. It may be that those authors are right who maintain that 
Roxburgh’s P, mttata is only a badly described P. longifolia ; it is, however, 
difficult for those who have had to follow Roxburgh’s work elsewhere and had occa- 
sion to test its excellence and accuracy to believe in this explanation. The care 
and precision of Roxburgh’s diagnosis are against the assumption, and the native 
artist who made the figure could have had no particular object in drawing a 
creeping rootstock if such were not before him. In any case the theory that 
Roxburgh and his artist were alike in error cannot be admitted till the Sundri- 
buns have once more been carefully searched for this fern,
