Laing. — Revised List of the Norfolk Island Flora. 27 



CaJcile maritima Scop. Reported only by Maiden. 



Almost certainly introduced and adventive. New Zealand examples 

 show how easily even a maritime plant may be introduced, and appear 

 in unexpected situations. Probably most of the supposed " Scandinavian 

 element '" in southern floras is due to such introductions. 



Capparidaceae. 



L05. Capparis nobilis (Endl.) F. v. M., M. 5. (= Busbeclcia nobilis, Endl., 

 E. 121.) 



A common bush liane, scrambling to the tops of the trees. Known on 

 the island, on account of its recurved spines, as " Devil's guts." 



Apparently endemic, but very close to the Australian C. arborea, F. v. M. 

 (Frag., i., 163). 



It may possibly be the same as the Queensland C. ornans F. v. M., but 

 I have no material with which to decide the question. The following points 

 should be noted with regard to the Norfolk Island plant : It belongs to 

 the section of the genus that has the two outer sepals united in the bud ; 

 the non-flowering branches are provided with two reflexed stipulary spines 

 about 6 mm. long. According to Maiden, the fruit is almost globular, but 

 this is scarcely so. It is globular only in the early stages, and when mature 

 the fruit is usually of the size, shape, and colour of the common edible passion- 

 fruit (Passiflora edulis). Occasionally only is it nearly globular. 



PlTTOSPORACEAE . 



106. Pittosporum bracteolatum Endl., E. 138. M. 9. 



Common in the bush. 



Endemic. 



I have also a fragment of an undetermined Pittosporum collected on the 

 island by Mr. H. C. Quintall. and forwarded me' by Mr. W. R. B. Oliver. 

 It may well be introduced. 



Leguminosae. 



107. Canavalia obtusifolia P. D.C., M. 30. (= C. Baueriana Endl., 



E. 150.) 



Coastal banks ; common. 



Kermadecs, Lord Howe, Australia, and tropics. 



108. Milletia australis (Endl.) Benth., M. 28. (= Pterocarpus australis 



Endl., E. 152.) 



Now confined to a strip of country running across the middle of the island. 

 As it rarely fruits, it is doubtless doomed to extermination. I saw only 

 one legume. 



Phillip Island (A. Cunn.), Australia. 



109. * Vigna retusa Walp., M. 31. (= Callicysthus volubilis Endl., E. 149.) 

 Lord Howe, New Caledonia, Australia, and widely in the tropics. 



110. Caesalpinia Bonducella Fleming, M. 32. 



A few specimens only exist in an open paddock near the centre of the 

 island. Apparently found only by Cunningham and myself. It is quite
