Casuarina Luehmanni, B.. T. Baker. 



The Bull Oak. 



Botanical Name.— Casuarina, already explained, Luehmanni, in honour 

 of Joliann Georg Luehmann, successor of Mueller in the post of Government 

 Botanist of Victoria, and who died in 1904. 



Vei-nacular Names. — " Bull Oak " is certainly its commonest name, being 

 in use over extensive areas in New South Wales and South Australia. 



In South Australia it is often called " Swamp Oak," according to Mr. 

 Walter Gill, for it often grows in land liable to inundation. 



Leaves. — It is an erect species with rather wiry branehlets, which some- 

 times take on the habit as if they were electrified, and endeavour to stand 

 apart from each other. This habit, it will be understood, is difierent from 

 that of most species of the genus, whose branehlets are more bunchy and 

 compact. 



In times of drought used for feeding stock, but is very binding when used 

 to any extent by itself. (District Forester Marriott, Dubbo.) 



Fruit. — The fruit in this species is so exceptional in shape that it appears 

 desirable to draw special attention to it. 



Timber. — Of a red colour, and of rather a coarse grain; one of the species 

 whose medullary rays stand, out prominently, rotting last, when a tree is 

 felled. 



This tiniber appears to be of little merit. It is small as a rule, and is 

 used for firewood locally. 



District Forester Marriott, of Dubbo, says of it: — 



This Oak is chiefly used for firewood in this district, and is considered one 

 of the best timbers for this purpose. Used for rails and fencing purposes. 



Mr. Walter Gill, Conservator of Forests, Adelaide, says of it : — 

 Timber of rather large figure ; durable for fencing-posts. 



Size. — It is a tree of small or medium size, say up to 40 feet in height, with 

 a stem diameter of a foot. 



Habitat. — This species occurs in l^ew South Wales and Queensland; 

 also in South Australia and Victoria. 



New South Wales. 



In this State it belongs to the drier parts, e.g., the western plains and 

 western islopes, while some eastern localities, e.g.. Singleton, &c., are 

 interesting because they represent districts in which the western or Eremaean 

 flora has descended to comparatively near the coast. 



Following are some localities represented in the National Herbarium, 

 Sydney: — Deniliquin (Forester O. Wilshire) ; Barham', Murray Eiver 

 (Assistant-Forester Chanter); Balranald (Forester G. S. M. Grant),; "West 

 of Grenfell" (District Forester Osborne). 



This is the Forest Oat of the Wellington country, and is a tree very similar 

 in appearance to the Swamp Oak (C. glauca, Sieb.) of Port Jackson. It is 

 a tree of about 50 feet in height, and of a stifC and by no meaii,s ornamental 

 appearance. November, 1851. (The late C. Moore.) 



Minore, near Dubbo (J. L. Boorman) ; Dubbo district (District Forester 

 C. Marriott) ; Oastlereagh River ( ? Collector) ; between Gilgandra and 

 Gummin Gummin (W. Forsyth); Najrabri (J.H.M.) ; Gulgong (J.H.M, 

 and J. L. Boorman). 



Emmaville.— Trees 20-40 feet high, 8-12 inches in diameter. Fairly plentiful 

 in one particular district ouly, viz., Kennedy's Paddock. (.1. L. Boorman.)
