DESCRIPTION. 



XXXVII. Eucahjptiis Boormani, Deane and Maiden. 



Froc. Linn. Soc. N.S. Jr., xxvi, 339 (1901). 



Biirk. — l>iirk in colour, often very dark gi'ey 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 bi'anches. 



Tilllbor. — Pale reddish-brown in colour, hard and durable, and, according to the testimony of 

 many observers, while of an Jronbark character, even superior to the Ironbarks of the district in which it 

 grows. 



Sucker leJlVCS. — 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 

 breailth ; veins tine and rather sprending, the inlraniirginal vein usually c]uite close to the edge. Texture 

 of the leaf coriaceous and tough, like that of E. si'Ierophloin. 



Buds.- -The buds and stamens appear to us not to diflfer from those of E. s icier iiphloia. 



Operculum. — Conical, like that of E. siderophloia, but we have not otiserved the operculum much 

 to exceed the calyx, which is very connnonly the case in E. siderophloia, especially in \ar. rostrata. 



Fruits. — Nearly semiovate, often slightly angular, usually presenting a good deal of resendjlance 

 to those of E. siderophloia, but the valves (which usually number four, and sometimes five) scarcely exserted. 

 About three to four lines in diameter, and not contracting at the orifice. Sometimes .so subcylindrical in 

 shape as to exhibit considei-able resemblance to those of typical E. hemiphloia, F.v.M. {op. cit.). 



Notes supplementary to the description. 



Named in lionour ol' John Luke; Boorman, Collector, Jiotanic Gardens, 

 Sydney, who, in regard to this and other species, has prosecuted inquiries in an 

 intelligent and painstaking manner. 



The name " Black Box " seems to l)e most generally in use for this species ; 

 the even better name of "Ironbark Box" (which certainly indicates its affinities) 

 is nearly as frequently in use. At Ltie it is also called " She ironbark," its 

 difference from the ordinary Ironbarks being thus recognised. 



This seems to me to be a natural hybrid between E. siderophloia, Benth., and 

 E. heiidphloia, P.v.M. The evidence available is published by Mr. Henry Deane 

 and myself in Froc. Linn. Soc. N.SJF.,x^\, p. iii (1900), and xxvi, p. 339 (1901). 

 Later on, xxx, p. 494 (1906), 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. 



As it is my intention to publish, later on, an account of hyln'idisation in 

 Eucalyptus, with necessary illustrations, I will not present the evidence at this place.
