 quite naked ; prim, pinnce 1^ ft. 1., 6-10. in. w. ; pinnl. 3-4 in. 1., ^-| in. w., 

 oblong, acuminate, deeply pinnatifid, or, towards the base even pinnate ; ult.

Hab. Tasmania and Australia, especially in the South ; Hastings and Clarence Rivers, 

 Beckler ; Louisiade Archip., McGiUivray, n. 456. 



45. A. Colensoi, Hk. f. ; unarmed, caud. small, to 4-5 ft. 1. ; st. short, densely

 small bullate scales ; fr. submembranaceous, subhirsute, 2-4 in. 1., 10-12 in. or 

 more w. ; prim, pinnce 12-14 in. 1., oblong, acuminate ; pinnl. 2 in. 1., 4-5 in. w., 

 rather distant, deeply nearly to the costa pinnatifid ; lobes 2-3 lines 1., ovato- 

 oblong, strongly serrated ; veins all simple ; sori small, nearer the costule than 

 the margin. Hk.f. Fl. N. Zeal. 2. p. 8. t. 73. 



Hab. New Zealand, Northern Island, Colenso ; Otago, Sinclair. 



46. A. excelsa, Br. ; st. and main rachises muricated ; fr. ample, coriaceous, 

 dark green above, paler beneath, when young more or less ferrugineo-tomentose 

 beneath, mixed with copious, small, bullate scales on the costce and costules ; 

 prim. pinn. 1^-2 ft. 1., 6-10 in. w. ; pinnl. numerous, approximate, oblong-lan- 

 ceolate, acuminated, deeply to the costule pinnatifid, often quite pinnate ; lobes 

 or ult. pinnl. |-f in. 1., oblong or linear-oblong, acute or obtuse, falcate, the 

 margins subrecurved, serrated ; veins once or twice or more forked ; sori copious

Hab. Norfolk Island ; Illawara, C. Moore, and Hastings River, Australia, Beckler ; 

 Mount Lindsay, Walter Hill. Said to have a trunk 60-80 ft. 1. The segments of the 

 sterile fronds are larger and broader than the more coriaceous fertile ones, and of a 

 paler green. It appears to be a larger and stouter-growing plant than A. australis. A 

 plant, in every respect resembling the A. exceha, has been sent living to Mr. Veitch, and 

 has been cultivated in gardens under the name of A. Cooperi, in compliment to Sir Daniel 

 Cooper.
