New Zealand Ferns 
(28 )T.elongatum (lengthened). Easily recognised 
by the dark olive-green, the broad triangular shape of 
the frond, and the long bristles that sometimes cover the 
under surface so thickly as to give it a brown colour — a 
peculiarity that no doubt suggested the name. 
Description . — Root short, stout, erect or inclined, not creep- 
ing. Stalks 3 to 9 inches long, stout, rigid, with a tuft of bristles 
at the base. Fronds somewhat scanty, 3 to 8 inches long by 11 
to 3 inches broad, dark olive-green, often coated on the upper 
surface with moss. Seeds numerous. 
North Island : Abundant in dark woods north of East Cape ; 
from thence to Cook Strait rare and local. South Island: Nelson, 
Marlborough, Canterbury. Sea-level to 2,500 feet. 
To find this fern it is necessary to go to the wettest 
and shadiest corner of a bush gully, such as the steep 
mossy bank by a waterfall. A difficult species to grow; 
in transplanting, care must be taken not to disturb the 
roots. Though closely allied to the wide-spread T. rigi- 
diun, it is found only in New Zealand.
