A very beautiful Fern, common in Tasmania, South Chili, and Fuegia ; found also in South Africa, Ceylon, 

 and the Malay Peninsula, varying extremely in size and habit wherever found ; it clothes trunks of Tree-ferns in 

 Tasmania with a glistening- garment of the most delicate and beautiful green, the fronds hanging down and over- 

 lapping one another in profusion. It may be readily recognized by its hair-like stipes and rachis, transparent mem- 

 branous fronds, and broad, short, terminal involucres. — Fronds 1-8 inches long, broad or narrow, linear, bipinnati- 

 fid. Pinnce short, often very irregular and unequal, distant, or close and overlapping one another. Segments short, 

 broad. Involucres rhomboid, wholly sunk in the ends of the segments, very flat, with short, broad, entire lips. 



7. Hymenophyllum pulcherrimimi, Col.; elatum, fronde ampla glaberrima membranacea ovato-lanceo- 

 lata tri-quadripinnatifida, segmentis patentibus breviusculis linearibus marginibus planis v. undulatis, 

 involucris parvis liberis axillaribus v. segmentis brevibus terminalibus sessilibus orbicularibus compressis 

 fere ad basin bifidis, valvis latis integerrimis, stipite rachique valida ad basin alata, rhizomate brevi crasso 

 pilis rigidis vestito, radicibus lanatis. — Colenso in Tasm. Phil. Journ. Hook. Sp. Fil. v. I. p. 103. t. 37 A.

Hab. Northern Island : mountains of the East Coast and interior, Colenso. Southern Island, pen- 

 dulous from trees, Lyall. 



A very handsome species, conspicuous for the very stout rachis and stipes, the latter winged to the base, for the 

 very short rhizome, which is clothed with dark brown shining bristles, and the woolly root-fibres.— Frond 12-18 

 inches high, broadly ovate or linear-oblong, twice or thrice pinnatifid. Primary branches (pinnas) spreading, long ; 

 secondary (pinnules) short, cut into alternate, linear, blunt, membranous segments. Involucres small for the size of 

 the plant, quite orbicular, free, axillary or terminating short segments, divided nearly to the base ; the lips quite en- 

 tire. — Plate LXXIV. Fig. 1, portions of frond ; 2, involucre with one valve removed ; 3, receptacle ; 4, capsules ; 

 5, spores : — all magnified. 



8. Hymenophyllum dilatatum, Sw. ; elatum, erectum pendulum v. decurvum, fronde ampla ovata v. 

 lineari-oblonga glaberrima tripinnatifida, pinnis (ramis primariis) ovatis ovato-lanceolatisve secundariisque 

 (pinnulis) basi cuneatis subfiabellatim lobatis, segmentis late linearibus cernuis saspe caudatis, involucris 

 terminalibus orbiculatis infra medium cuneatis fronde immersis segmento latioribus profunde bitidis, valvis 

 integerrimis, rachi stipiteque valida fere ad basin alatas, rhizomate valido elongato glaberrimo. — Sw. Syn.

A magnificent Fern, the noblest of the genus, and a very common one in New Zealand, also found in Java and 

 in Lord Auckland's Island. It resembles II. pulcherrimmn in many respects, but differs remarkably in its brighter 

 green colour, narrower, often decurved fronds, quite glabrous, elongated rhizome, and root-fibres, less winged stipes, 

 shorter pinnae, often tailed segments, which are much broader, and in the terminal and larger involucres. It often 

 attains If foot in height. 



9. Hymenophyllum crispatum, Wall. ; erectum, fronde ovata v. lineari-ovata bi-tripinnatifida ; seg- 

 mentis linearibus planis undulatisve, involucris terminalibus liberis sessilibus ovatis turgidis ad basin par- 



titis, valvis integerrimis erosisve, rachi stipiteque late alatis ala plana undulata v. crispata. Wall. Cat.
