I have ventured to restore Mr. Colenso’s H. atrovirens to the rank of a species, for 
although undoubtedly very close to A. australe it appears to differ sufficiently in the 
much snaller and narrower more sparingly divided frond, in the flat (not crisped) wings 
to the rhachis and stipes, and in the narrower segments and smaller ovate indusia. 
Mr. Kirk’s H. montanum is clearly the same plant, with the indusia conspicuously jagged. 
Whether the Australian plant included under atrovirens by Baker is also identical I am 
unable to say, not having seen specimens.

Forming dense tufts on the branches and trunks of trees. Rhizome short, 
stout, densely clothed with shining red-brown bristly scales; rootlets 
woolly, Fronds very handsome, pale-green, erect or pendulous, 9-30 in. 
long including the stipes, 2-6in. broad, ovate-lanceolate or linear-oblong, 
acuminate, membranous, flaccid, quite glabrous, 3-4-pinnatifid. Stipes 
2-6 in, long, winged to the base; rhachis also with a narrow wing through- 
out its length, wings not crisped. Primary pinnae 14-3in. long, rhom- 
boidal-lanceolate, 2-pinnatifid down to a narrowly winged flexuous rhachis. 
Ultimate segments simple or forked, linear, flat, obtuse or retuse, quite 
entire. Sori terminating short lateral segments, sometimes apparently 
axillary, quite free. Indusium orbicular, 2-valved to the base; valves 
convex, quite entire—Hook. Sp. Fil. i (1846) 108, t. 374; Hook. f. Fl.

7. H. dilatatum Swartz Syn. Fil. (1806) 149.—Large, very handsome, 
bright-green, clothing the trunks of trees or rotten logs. Rhizome long, 
Stout, wiry, glabrous. Fronds variable in size, usually 9-18 in. long includ- 
ing the stipes, but luxuriant specimens often reach 2 ft, or more, the 
smaller specimens erect or decurved, the larger usually pendulous, 3-6 in. 
broad, ovate or ovate-lanceolate to linear-oblong, membranous, 3-pinnatifid. 
Stipes 2-6in. long, terete, wiry, narrowly winged almost to the base: 
rhachis winged throughout, the wing flat, not crisped. Primary pinnae 
13-3 in. long, ovate-lanceolate, cuneate at the base ; secondary broad, 
almost subpalmate below, irregularly pinnatifid. Ultimate segments linear, 
often elongated and decurved, about z's in. broad, obtuse, flat, quite entire. 
Sori numerous, terminating the segments, sunk in the frond at the base. 
Industum orbicular, cuneate at the base, 2-valved more than half-way down ; 
valves convex, rounded at the tip, entire; clusters of sporangia often 
exserted-—Hook. and Grev. Tc. Fil. (1829) t. 60; A. Cunn. Precur. (1836)
