30 Diagnostic Notes on New or 



somewhat 1 line in length. Anthers cordate. Style 2 

 thirds of line long. Stigma minute trilobed. 



Denhamia pittosporoides. 



Young branchlets angular ; leaves oblong-lanceolate, gra- 

 dually tapering into a short petiole, crenate denticulate, 

 on both pages of equal colour; capsule small, four- 

 valved, four-seeded, perfectly four-celled. 



In the Araucaria Ranges on the sources of the Burnett 

 River. C. Moore. 



Leaves more intensely green and stronger veined than in 

 any of its congeners, 2-4 inches long, 6-10 lines broad. Calyx 

 normal. Valves of the capsule about \ inch long, as well as 

 the dissepiments bony. 



To Mr. Black, the intelligent keeper of the Hookerian 

 Herbarium, I am indebted for identifying the two first spe- 

 cies of this genus with Leucocarpon, an information which, 

 without reference to authenticated specimens, hardly could 

 have been obtained, since Richard described the fruit as sub- 

 carnose. Mr. Black even believes, that Denhamia xantho- 

 sperma is identical with Leucocarpon obscurum ; but the 

 latter being found on the sub-tropical Eastern coast, and the 

 former only hitherto on the fall of the waters to the north 

 coast, I deem it preferable to hold the two distinct, until 

 flowering specimens are procured of the Leucocarpon from the 

 locality mentioned by Richard. Denhamia Oleaster and D. 

 pittosporoides are too imperfectly known to render their 

 position in this genus certain. I have referred all these 

 plants to Celastrinese, since the flowers seem to point out a 

 closer alliance to that order than to Bixaceae. If this view 

 be adopted, the genus Denhamia will be placed near Put- 

 terlickia. 



Celastrus Cunninghami. 



(Catha Cunninghami, Hook, in Mitch. Trop. Austr., p. 387. Sect. Catha.) 



Unarmed, glabrous; leaves scattered, coriaceous, lanceo- 

 late or narrow-linear, entire or rarely towards the apex 

 denticulate ; pedicels axillary, solitary, fasciculate-race- 

 mose, or rarely paniculate ; capsules small, obovate, turgid, 

 bivalved, one-celled, one seeded; seeds ovate-globose, 

 shining-black, enclosed in a pulpy arillus. 



From Port Jackson (where it was found by W. Woolls, 

 Esq.), extending as far as North-west Australia.
