 J. D. Hooker. — //. crispatum, as figured in the ' Icones Filicuu],' I possess 

 from Nc]ial. The Ceylon specimens are smaller, with narrower and copi- 

 ous fructifications, scarcely half the size of the former. Those I call y. are 

 larger, with the involucres twice the size of /3., still more copious, especially 

 at llie ajiices of the ultimate segments. The specimens from Tasmania ap- 

 j»i-ar quite to agree with iMr. Brown's Il.jiahellatum (not Labill.), for the 

 slight diflerences would scarcely justify their being kept distinct. Among 

 my abundant specimens from that country the fronds are more or less crisp- 

 ed, or sometimes wholly plane. The involucres, always terminal on elon- 

 gated segments, are nearly orbicular in some instances, in others ovate, en- 

 tire or erose. iMr. Colenso's beautiful specimens from New Zealand (//. 

 alrovirens. Col.) have the segments of the fronds almost entirely plane, the 

 involucres smaller and exactly ovate. 



58. H. Jlexuosum, A. Catni. ; fronds erect rather rigid 

 broadly ovate almost deltoid tri-quadripinnatifid, the seg- 

 ments narrow linear entire obtuse undulated, involucres rather 

 broader than the segment terminal free orbicular entire 2- 

 valved to the base, the valves convex, receptacles included, 

 rachis as well as the stipes with a broad crisped wing. A.

Uab. New Zealand, northern island, All. Cunningham, Colenso. — This 

 bears the rounded involucres of //. Javanicum, but they have the tenninal 

 insertion of //. crispatum. The fronds are more deeply and copiously di- 

 vided than in either, more crisped, especially in the rachis and stipes ; and 

 the general habit is different ; yet it must be confessed that in many re- 

 sj)ects it appears intermediate between the two just mentioned.
