Bentham and Hooker (Genera Plantarum, iii. 178) reduce these 

 to two, pointing out that M. verticliiata has been erroneously 

 described as a Macadamia from a cultivated plant in the Botanic 

 Gardens, Sychiey, which has been proved to be a South African 

 plant B fdbf'j nm Ktellal/ifoliuvi, Linn. The species has since been 

 lost to the Garden. 



F. V. Mueller (Census of Australian Plants) recognises but one 

 species of Macadamia, viz., M. ternijolia, — M. Youngiana being 

 transferred to Hel.icia. 



Baillon unites Macadamia, as well as sevei^al species hitherto 

 described under Helicia, with the Aiwev'icixn geiwxa Andripelahim, 

 .Schott (Baill. Vol. ii. p. 414). The characters of Andripetaliim 

 are ovules 2, descending, suborthotropous. 



A. Engler (Die natiirlichen PHanzen-familien) recognises 

 Macadamia 1 species in Australia; HtUcia 25 species in Asia, 

 Malayan Archipelago, and Australia; A)idripetalum is not men- 

 tioned. We are, however, of opinion that Engler probably followed 

 Baron von Mueller with regard to Australian plants of these 

 genera. 



Kute on a I'lanf, hitherto only recorded from New Guinea, found 

 in Neto South Wales. 



Clieirostylis grandiflora, Blume, " Collection des Orchidees les 

 plus remarquables de TArchipel Indien et du Japon," Plate 13. 

 " In moist forests between rocks on the coast of New Guinea." 

 A plant of this species was collected by Dr. W. Finselbach on 

 rocky hills "in a shad}^ localit}^ in the dense scrub," on the 

 Richmond RiA^er, near Lismore. It will be seen that in New 

 South Wales it grows under conditions practically identical with 

 those under which it occurs in New Guinea It is a very pro- 

 nounced sapropliA^te, growing on dead leaves. In fact some of 

 the Richmond River specimens were living on a layer of leaves 

 only I inch thick, and under this layer was the bare rock. The 

 upper side of the creeping rhizome is nearly alwa3'^s exposed to 

 the light, or at all events to the air, and when it is found between 

 stones the rhizome is alwavs fixed to dead leaves.
