Istanps: Abundant in moist forests throughout. Sea-level to 2500 ft. 
Also in south-eastern Australia and Tasmania. Mr. Colenso’s 7’. venustulum is 
simply a small state with broader lower pinnae sometimes bearing 2—4 sori. 
5. T. Colensoi Hook. f. Ic. Plant. (1854) t. 9792—Pendulous from rocks 
or from the trunks of trees. Rhizome wide-creeping, branched, capillary. 
more or less tomentose. Stipes short, slender, naked. Fronds rather dis- 
tant, 2-5 in. long, 4-lin. broad, oblong-lanceolate or linear-oblong, acumi- 
nate, quite glabrous, membranous, dark-green, 3-pinnatifid ; rhachis slender, 
not winged. Primary pinnae 5-12 pairs, remote, shortly stalked, pinnate 
at the base, pinnatifid above. Ultimate segments very narrow-linear, 
acute, quite entire; a central costa only in each segment. Sori solitary 
on the upper side of a pinna near its base and thus appearing axillary, 
erect, stipitate, quite free. Indusium tubular, the mouth sie utty dilated. 
Receptacle usually exserted as a long capillary bristle.—Hook. f. Fl. Nov,

6. FT. strietum Menz. ex Hook. and Grev. Ic. Fil. (1829) t. 122.— 
Rhizome very short, erect or inclined, stout, woody, emitting many long 
wiry rootlets. Fronds numerous, crowded at the top of the rhizome. 
Stipes 2-4 in. long, stiff, erect, terete, naked or narrowly margined above, 
furnished with a tuft of red-brown bristles at the base. Fronds 3-6 in. 
long, 13-23 in. broad, lanceolate cr linear-oblong, acuminate, rigidly erect, 
yellowish-green, 3-4- -pinnatifid ; ; rhachis narrowly winged throughout or the 
wing evanescent in the lower part. Primary pinnae close-set, lanceolate, 
ascending or spreading, the lower sometimes reduced in size; secondary 
pinnatifid. Ultimate segments narrow-linear, flat, entire, glabrous ; texture 
firm; costa stout, unbranched. Sori usually not very numerous, termi- 
nating short segments near the base of the upper margin of the secondary 
pinnae. Indusium ENG free, erect, funnel-shaped, mouth dilated all round.
