AFFINITIES. 



1. With E. odorata, Behr. 



The odorata of Howitt's paper, "The Eucalypts of Gippsland." Trans. 

 Roy. Sac. Vict., 1890, is E. Bosistoana. 



The Bairnsdale Grey Box is oue of our most durable, and fr-oin the large size attained, one of the 

 most valuable of our timber trees. Until I examined its characters critically, and until its botanical 

 peculiarities were investigated, at my instance, in collections which I forwarded to Baron von Mueller, it 

 was considered locally as "Yellow Box" {E. melliodora), to which it has a slight superficial resemblance. 

 —(Report of A. W. Howitt, 1895.) 



It differs from E. odorata in tlie greater paleness of its timber, its more erect 

 habit, and in other cliaracters. 



E. Bosistoana belongs to a group of species including E. odorata, melliodora, 

 leucoxylon, and others, which liave almost similar rims to the nearly ripe fruit. 



2. With E. hemiphloia, F.v.M. 



E. Bosistoana is often known as "Yellow Box," it is also like E. hemiphloia, 

 sometimes known as " Grey Box." Both are U2:)right growing trees, with broad 

 suckers. It is called " Yellow Box" at Cabramatta (Dr. WoolJs' original locality 

 for the species), and I was at considerable pains, with Mr. Hoy, a local resident, and 

 Mr. Boorman, to ascertain the local differences between it and E. hemiphlol '. 



E. hemiphloia is known locally as " Grey Box." E. Bosistoana (" Yellow 

 Box") has straighter timber than the Grey. It grows on swampy, low ground, but 

 then keeps shrubby ; on high ground it makes good timber. 



The Grey Box timber turns black or grey ; the Yellow Box keeps yellow for 

 a long time, and this colour shows in old timber when freshly adzed. This is the 

 origin of the name. Grey Box keeps on dry, hilly ground. 



The fruits of E. hemiphloia are more cylindrical. 



3. With E. melliodora, A. Cunn. 



It is worthy of note that the immature fruits of this species have a marked 

 outer rim such as is a prominent character in E. melliodora . 



An axe-cut readily shows the difference between the two species, E. 

 Bosistoana having a white sapwood, and E. melliodora a yellow one. The foliage 

 of the latter is more glaucous, more pendulous, and altogether less rigid, than that 

 of the former. 'J he fruit is also smaller and more cylindrical. 



4. With E. leueoxylon, E.v.M. 



The specimen collected by Oldfleld, many years ago, was labelled E. 

 leujoxi/lon. The juvenile foliage of both species is broad ; the fruits of E. 

 Bosistoana are, however, much smaller than those of E. leueoxylon and the 

 inflorescence very much less sparse. The juvenile foliage of the latter and of the 

 tree generally is more glaucous. The shapes of the juvenile leaves are different,
