specimens of D. Baueriana^ Mast., if they can now find it; and 

 also a few ripe fruits of both species in order that I may raise 

 some plants. The difference in the colours of the flowers and 

 fruits of the two species should be noted. 



There is plenty of the common Passion Vine {Passijioraedulis) 

 growing wild. 



CUCURBITACE^. 



38. Bryonopsis affixis, Cogn., in DC. Monogr. Phan. iii. 479. 

 (Syn. Bryonopsis Pancheri, Naud., and Bryonia affinis, Endl., 

 Prod. ^ovi. 125). 



39. SiCYOS ANGULATA, Forst., Prod. 1796. (Syn. S. australiSf 

 Endl., Prod. Norf. 124, 1833). — Called "Cucumber" on the 

 Island. 



40. Melothria Baueriana, F.v.M., Fragm. vi. 188, 1866. 

 (Syn. Zehneria Baueriana, Endl., Prod. Norf. 126 ; Zehneria 

 Baueriana, in Benth. k Hook., Gen. Plant, i. p. 830). — Called 

 " Giant Cucumber " on the Island. 



FICOIDE^. 



Mesemhryanthemum australe, Sol., Endl., Prod. iSTorf. 129. — I 

 made diligent search for this species, but failed to find it. I have 

 not the German edition of Hunter quoted by Endlicher. 



41. Mesembryanthemum ^quilaterale, Haw. ("Pigs' Faces"), 

 is not uncommon. 



42. Tetragonia expansa, Murray, in Comni. Gotting. vi. 13, 

 1783, not Solander as given in Endl., Prod. Norf. 130.— Called 

 " Cook's Cabbage " on the Island. 



Endlicher recognises two varieties, cornuta and strongylocarpa^ 

 on the Island. The specimens collected by me belong to the 

 latter form; so do those in the herbarium from Lord Howe, New 

 Zealand and Australia. The form cornuta (floribus sessilibus) 

 appears to be rarer, but I have not seen it, and do not know 

 whether Endlicher's varieties have been accepted by others.
