608 ON TWO NEW SPECIES OF CASUAIiTyA, 



come under my notice. When placed amongst other Museum 

 specimens of She Oaks, it shows little or no affinity with them. 

 It is jjerhaps the hardest timber in the Western area of the 

 Colon}'. 



Fodder,— The branchlets are cut in considerable quantity for 

 fodder (R. H. Cambage). 



Casuakixa Luehmanni, sp nov. — "Bull Oak." 



(Plate xlvii.) 



A fair-sized tree, attaining a height of 70 to 80 feet, or rarely 

 100 feet, and a diameter of from 1 to H feet, rarely 2 feet. Bark 

 furrowed, brittle, and easily removed. Branchlets robust, light 

 coloured or glaucous, under a line (|) in diameter, about the same 

 thickness as in C. g/aiica, Sieb., the internodes ribbed, 6 lines 

 long, glaucous, the nodes yellow, sheath-teeth brown or l)lack,. 

 short, acute, 9 to 12 in the wlu)rl, mostly 11. 



riowei's dicecious. ]Male spikes about an inch long, of a light 

 golden-brown colour, clustered at the nodes toward the end of 

 the branchlets; internodes straw-coloured; teeth golden-coloured, 

 erect, short, acuminate, constricted at the nodes. 



Fruit cones flattened, about ^ inch in diameter, and consisting 

 almost uniformly of three discs or rows of valves, but often 

 irregularly shaped, owing apparently to onl}' a few of the seeds 

 being developed. Valves protruding, prominent, sometimes 

 pubescent at the back and front, with a well defined dorsal pro- 

 tuberance extending from the base of the valve to half its length 

 and ending in ah abrupt angle broadly obtuse or shortly acumin- 

 ate. Nuts small, dai'k brown, shining, with a short samara. 



Hab. — -Forbes, Parkes, Condobolin (E. H. Camhage), Grenfell, 

 Bourke to Barringun. 



The range is almost identical with that of " Belah," C. Camhagei. 



Following Bentham's classification (B.Fl. Vol. vi. p. 194), this 

 species belongs to the section Leiopitys — ^whorls 7-16-merous, and
