Laing. — Revised List of the Norfolk Island Flora. [\ 



N. calanthum as identical with the following fern of this list — Polystichum 

 aristatum. Maiden considers these as more probably synonvmous with 

 Aspidium decompositum Spreng. ; but apparently did not himself find it on 

 the island, nor did I. When so much is doubtful, and the fern has not been 

 recently found, it should. I think, be excluded from the list. 



■8. Polystichum aristatum (Sw.) Pr. (= Aspidium aristatum Sw., E. :>3. 

 M. 39.) (See also above.) 



Everywhere abundant in the drier bush. 



Kermadecs, Australia, New Zealand, and widely in the Southern Hemi- 

 sphere. 



9. Polystichum adiantiforme (Forst.) J. Sm. (= Aspidium coriaceum 



Sw., E. 22 ; A. capense Willd., M. 40.) 



Australia, New Zealand, and widely throughout the Southern Hemi- 

 sphere. 



10. Arthopteris tenella (Forst.) J. Sm. (= Polypodium tendlum Forst.. 



E. 18, M. 5.) 



Climbing on trunks of trees. 



Lord Howe, Australia, New Zealand, New Caledonia. 



11. Nephrolepis cordifolia (L.) Pr., M. 46. 



Pop Rock and rocky ledges. 



Kermadecs, Lord Howe, New Caledonia, Australia, New Zealand, and 

 widely in the Southern Hemisphere. 



(Called on the island " Pop Rock fern.") 



12. Davallia pyxidata Cav., M. 48. 



Mount Pitt. 

 Australia. 



13. Athyrium umbrosum (Ait.) Pr., M. 36. (= Alkudodia australis 



R. Br., E. 31 ; Asplenium assimile Endl., E. 30.) 



In the denser bush, Mount Pitt. 



Australia, New Zealand, and widely in warmer regions of the Eastern 

 Hemisphere. 



Athyrium brevisorum Wall., M. 37, is also recorded by Maiden from 

 Norfolk Island, but as this is a fern of northern India there is probablv 

 some mistake in the matter, and I hesitate to introduce it into the list. 



14. Diplazium japonicum (Thbg.) Bedd., M. 35. 



Mount Pitt ; not common. 



Kermadecs, Australia, New Zealand, Polynesia, and tropical Asia. 



15. Asplenium nidus L., E. 26, M. 30. 



Everywhere common in the damper bush. 



Lord Howe, New Caledonia, Australia, Asia, Polynesia, Africa. 



15a. Asplenium Robinsonii F. v. M., M. 31. 



Norfolk Island ; very rare. 



I retain this with much hesitation. It seems to me that this is probably 

 -only an occasionally occurring crested and incised sport or mutant from 

 the previous. I did not myself see it growing wild. The only living speci-
