4. E. luemastoma, Miq. 



16. Eucalyptus luemastoma, Smith, Act. Soc. Linn. Lond. iii. 285 ; DC. Prodr. I.e. 219, n. 23. — E. 

 largiflorens, Ferd. Mull. Herb. 



Locis humidis ad fl. Murray, fl. estate (F.M.). Van Diemensland (Stuart). 



Umbellai sub-5-florje, nunc superne paniculato-conferte. Operculum duplex ; exterius depressum 

 obsolete apiculatum, interius membranaceum convexum muticum ; calycis tubus (p. 131) obconicus apice 

 ampliatus hoc paulmii, illo duplo amplior, ambobus multo longior (ex Mull, adnot.). Nederl. KrvAclk Arch. 

 iv. 130 (1856). 



This is E. bicolor, A. Cunn., "as to the Murray specimens" (B.FL iii. 215). 

 The Tasmanian (Van Dieman's Land) specimens were probably E. amygdalina. 



(«) Note on E. parviflora, F.v.M. 



This is a name only given as a synonym of E. bicolor, A. Cunn. (in Joum. 

 Linn. Soc. iii. 90) and it is referred to here in order that it may be cleared up. It 

 is the same as E. bicolor, A. Cunn., var. parviflora, F.v.M. (B.Fl. iii, 215) and is 

 E. populifolia, Hook., as noted by Mueller himself in Herb. Melb. It is, doubtless, 

 the same as " var. parviflora, Benth." (should be F.v.M., "Eucalyptographia" under 

 E. largiflorens). 



(b) Note on E. bicolor, Duff {partim). 



E. bicolor, Buff, in " Catal. of N.S.W. Forestry Exhibits," Melbourne, 

 Adelaide, and other Exhibitions, is called " Slaty Gum," and its timber is described 

 as " hard, tough, strong, durable, and said by experts to be one of the best 

 hardwoods ; used for fencing, wheelwrights' work, bridges, railway sleepers, and 

 house building; plentiful, flab, open forests south-western river districts, Blue 

 Mountains, and the Darling Biver." 



It is evident that the above partly refers to E. bicolor, A. Cunn., and to 

 E. polyanthemos, Schauer, and it is only referred to on the present occasion as the 

 source whence E. bicolor, " Slaty Gum," has crept into numerous official reports. 



RANGE. 



It seems to be confined to South Australia, Victoria, New South Wales, and 

 Queensland. 



From St. Vincent's Gulf and the Murray River and its lower tributaries, through eastern Australia, 

 and particularly its eastern tracts to Carpentaria, at least as far as the Flinders and Gilbert Rivers, but 

 reaching also, in some places, the coast tracts. — (Mueller, in Eucalyptographia.) 



This reference to "coast tracts" applies, as regards eastern Australia, to 

 Queensland solely. E. bicolor is a dry country species, and in central and northern 

 Queensland many western New South Wales species approach the' coast. It prefers 

 rich flats which are liable to occasional submergence.
