THE NORTH-AUSTRALIAN EXPEDITION. 197 



Eastern Australia, no doubt the plant mentioned by Professor Lindley 

 in his valuable ' Vegetable Kingdom.' 



Of Pittosporece I obtained two new genera in Eastern Australia, be- 

 sides a new Pittosporum from Arnheim's Land, as well as some addi- 

 tions to the latter genus from Central Australia, contained in the not 

 yet arrived division of the collection. 



Amongst Olacinea we meet the strange face of a Ximenia, allied to 

 the New-Caledonian X elliptica. 



Ampelidece comprise only the genus Cissus, but this in seven well- 

 marked species, whereas I find only C. Baudiniana> Brouss. (very im- 

 properly called C. antarctica by Vent.) enumerated amongst Australian 

 plants by previous writers. A wo^-climbing herbaceous species from 

 the Victoria River (C. acida) proved useful as an antiscorbutic vege- 

 table. 



Sapindacece exhibit some of the finest trees in Eastern Australia. 

 That section of Nephelium separated by Professor Blume as Arytera 

 contains four very distinct species. Atalaya seems also to occur. lie- 

 terodendron, very properly referred to this Order by Dr. Planchon, differs 

 scarcely from Arytera except in simple leaves and apetalous flowers, if 

 not in structure of the embryo (the fruit not being found in sufficient 

 maturity for examination) ; a species with toothed leaves {Heteroden- 

 dron dlversifolium) has been added from the Brigalow Scrubs of Eastern 

 Australia. Distichostemon and Apophyllum form remarkable genera 



allied

Dodonaa with foliaceous wings to the capsule, the latter a quickly de- 

 foliated bushy tree, resembling a Hakea, with polygamous flowers, an 

 often two-seeded indehiscent fruit with circinate embryo. Dodonaa 

 flifolia (of which however no authentic specimens have been seen) 1 

 reduced to D. acerosa, Ldl., and D. mollis and triangularis have been 

 united as B. Lindleyana. D. pfojsocarpa is remarkable for inflated, 

 generally six-winged seed-vessels, and D.polyzaga singular for nume- 

 rous pairs of leaflets. The latter surpasses even your D. vt>stih, which 

 we never found, in beauty ; but both, as well as several other kinds 

 from North-western Australia, are wanting in this part of the collec- 

 tion. D. platyptera differs from D. Preissiana in very broad upward 

 truncated wings, and D. oxyptera, like D. physocarpa, a pinnate-leaved 

 species, is distinct from the rest in acute wings. 



The Meliace* I may perhaps consider as the most interesting part of 

 my collection, since the Order seemed formerly to be so scantily dcvdo; d
