ON A NEW SPECIES OF MACADAMIA, TOGETHER 

 WITH NOTES ON TWO PLANTS NEW TO THE 

 COLONY. 



By J. H. Maiden, F.L S., and E. Betche. 



Macadamia integhifolia, sp.nov. 



Small bushy tree, glabrous except the inflorescence and young 

 shoots. Leaves petiolate, irregularly wliorled in threes, oblong- 

 lanceolate, entire, obtuse, aljout 5 to 7 inches long, strongly 

 reticulate. Flo wet's in axillary simple I'acemes often as long as 

 the leaves, generally in pairs irregularly clustered on the rhachis. 

 Pedicels about 2 lines long, minutely pubescent. Corolla 2 to 3 

 lines long, nearly glabrous. Hypogynoiis glands united in a ring. 

 Ovidary hairy, style glabrous or nearly so, with a clavate stigmatic 

 end. Fruit globular, with a coriaceous exocarp and a hard 

 endocarp, about | inch diameter. 



Hab. — Camden Haven, New South Wales. Collected about 30 

 years ago either by Mr. Charles Moore or Mr. Carron, a former 

 Botanical Collector of the Sydney Botanic Gardens. 



Closely allied to the Nut-tree, Macadamia ternifolia, F.v.M. 

 (of New South Wales and Queensland), from which it is readily 

 distinguished by the petiolate entire lea^^es, rather smaller fruits 

 and less hairy flowers and inflorescence. 



It may be pointed out that the sucker leaves ha^e occasionally 

 leaves with toothed margins, and shorter petioles, somewhat 

 resembling the leaves of M. ternifolia, which shows the ancestral 

 relationship of both species of Macadamia, but as the full grown 

 leaves are constant in the characters indicated, and for other 

 reasons, we have no hesitation in keeping the two species separate. 



The following notes in regard to Macadamia and Helicia may 

 be convenient for reference. 



Bentham (Flora Australiensis, v. 406) recognises 3 species of 

 Macadamia, viz., M. Youngiana, F.v.M., M. ternifolia, F.v.M., 

 and M. verticillata, F.v.M.
