Eucalyptus Boormaili, Deane and Maiden. 
A Black Box. 
(Family MYRTACE^E.) 
Botanical description. —Genus, Eucalyyptus. (See Part II, p. 38.) 
Botanical description. —Species, E. Boormani, Deane and Maiden, Proc. 
Linn. Soc. N.S.W., xxvi, 339 (1901). 
Bark .—Dark in colour, often very dark grey and even black. In texture scaly, sometimes hard 
scaly, and even in parts nearly as rugged as an Ironbark, but never as soft as a Box The 
rough bark extends to the small branches. 
Timber .—Pale reddish-brown in colour, hard and durable, and, according to the testimony of 
many observers, while of an Ironbark character, even superior to the Ironbarks of the district 
in which it grows. 
Sucker leaves .—Broad and coarse, nearly orbicular, but early becoming lanceolate. 
Mature leaves. —Ovate-lanceolate to lanceolate, usually 3 to 6 inches long, and over 1 inch in 
breadth ; veins fine and rather spreading, the intramarginal vein usually quite close to the 
edge. Texture of the leaf coriaceous and tough, like that of E. siderophloia. 
Buds .—The buds and stamens appear to us not to differ from those of E. siderophloia. 
Operculum. —Conical, like that of E. siderophloia, but we have not observed the operculum much 
to exceed the calyx, which is very commonly the case in E. siderophloia, especially in var. 
rostrata. 
Fruits .—Nearly semiovate, often slightly angular, usually presenting a good deal of resemblance 
to those of E. siderophloia, but the valves (which usually number four, and sometimes five) 
scarcely exserted. About 3 to 4 lines in diameter, and not contracting at the orifice. 
Sometimes so subcylindrical in shape as to exhibit considerable resemblance to those of 
typical E. hemiphloia, F.v.M. (op. cit.) 
A Natural Hybrid .—This seems to me to be a natural hybrid between 
E. siderophloia, Benth., and E. hemiphloia, F.v.M. The evidence available was 
published by Mr. Henry Deane and myself in Proc. Linn. Soc. N.S. W., xxv, p. Ill 
(1900), and xxvi, p. 339 (1901). Later on, xxx, p. 494 (1905) I drew attention to 
the remarkable discovery by George Caley (botanical collector in New South Wales, 
1800-1810), of hybridisation between E. siderophloia and E. hemiphloia. 
I used the following words:— 
I desire to say that I have no doubt in my own mind as to E. Boormani being a hybrid between 
the species named. 
Here I would draw attention to my paper “George Caley, Botanical Collector in New South Wales, 
1800-1810,” in the Agric. Gazette, N. S. Wales (Oct. 1903, p. 990). Caley gave the aboriginal name for 
E. hemiphloia as “ Barilgora ” or “ Berigora,” and “ Derrobarry ” and also “ Burryagro ” for E. siderophloia. 
Attached to a specimen of E. Boormani Caley makes the following statement —“ Burryagro.” A hybrid 
between “ Barilgora ” and “ Derrobarry ” !
