606 ON TWO NEW SPECIES OF CASUARINA, 



The timbers differentiate these trees in a marked degree. The 

 timber of Sieber's C. glauca has the characteristic feature per- 

 taining to our She Oak trees — the medullary rays being very con- 

 spicuous and pronounced, producing an elegant figure when 

 the wood is cut on the quarter ; whilst "Belah," C. Cambagei, 

 possesses no figure whatever, and so in this respect shows no 

 affinity with any of the other species of the genus. In fact, 

 it was not till attention was drawn to this feature by Mr. 

 Cambage that a new species was detected in this particular case. 

 Bentham (B.Fl. Vol. vi. p. 196) under Sieber's C. glauca records 

 that species (amongst other localities) as ranging "from the 

 Lachlan and Darling Rivers to the Barrier Range." Now 

 Sieber's type with the " Smaller cones and very numerous rather 

 smaller valves very regularly arranged " was collected by him in 

 the coast disti'ict of the Colony; it does not extend beyond the 

 mountains, and it can be shown to be a distinct species from this 

 one, so that Bentham, working on herbai'ium material, might 

 easily be led to include the coast and interior trees as one and 

 the same species, as there is some resemblance in the branchlets 

 and pei'haps in the cones of the two. 



Sieber's C. glauca differs from this interior species in its "smaller 

 cones, and its smaller and more regularly arranged valves " — 

 which have not a dorsal thickening as holds in this species. 



The nuts of the two species never could be confounded— those 

 of C glauca being very small, with a narrow samara, whilst 

 those of this species are twice as long and have a broad samara. 

 The male spikes of C. glauca, Sieb., are twice the length and have 

 long revolute hair-like sheath-teeth in contradistinction to the 

 short and erect ones of this species. 



The valves of the fruits of this species are also quite distinct, 

 those of C glauca being of an uniform thickness; they are also 

 quite distinct from those of C. equiseti/olia, Forst. 



The cones ai-e allied to those of C stricta, Ait., and it might 

 here be stated that very possibly Bentham's synonymy under that 

 species (B.Fl. Vol. vi. p. 195) will require, in face of our present 

 knowledge, to be i-evised, as some of the species are quite worthy
