3. With E. viridis R. T. Baker. 



" The fruits arc small, and somewhat approach in shape those of the Greeu Malice, E. viridis Baker; 

 but the bark, timber, and chemical constituents of the kino and oil difierentiate it from that species." 

 (Original description.) (This pa.ssage is omitted from Research, &c., p. 133.) 



■' By the casual observer, it is sometimes confused with the large form of 

 E. viridis, which is also in places called Mallee Box, but with this tree it has no field 

 affinities." (R. H. Cambage in Proc. Linn. Soc. N.S.W., xxv, 714. 1900 ) 



For E. viridis (luider the name E. acacioides), see figs. 9-12, Plate 52, Part XL 

 As a very general rule, this is a slender, graceful Mallee. 



4. With E. bicolor A. Cunn. {E. pendula A. Cunn., see Part XI). 



" . . . . from E. jKndula A. Cunn., in the venation and shape of the leaves, the shape of the 

 fruits and constituents of the oil, and particularly in its timber, and it has a more erect habit than this 

 species." (Original description.) 



For E. bicolor see Part XI, with figs. 5-13 of Plate 49. I would be inclined to 

 say that E. bicolor has a more pendulous habit than those trees which have been 

 described as E. Woollsiana; it is a thick, rough-barked, pendulous, narrow-leaved 

 species, while E. Woollsiana has a paler and less rugged bark ; the colour of the timber 

 of E. bicolor is a rich reddish brown. 



5. With E. populifolia Hook. 



" E. ■popidijolia has much wider leaves, but the bark of the species is very similar [but is not 

 associated in any other respect with this species]. (These words in square brackets are omitted from 

 Research, &c., p. 133.) Mx. W. Baeuerlen states ' that it is usually associated with E. populifolia, the 

 Green Mallee (E. viridis Baker), ■%nd the Grey Mallee (E. Morrisii Baker), on which account it is called 

 ' Mallee Box.' I have never seen it in Mallee form, and as a result of my enquiries it appears that it does 

 not grow in that form.' " (Original description.) 



For E. fopulifolia see Part X, Plate 48. The two species are very dissimilar, 

 the only approach (distant) being in the infrequent narrow-leaved form of E. populifolia, 

 and in the small fruits, which are, however, difierent in shape. 



6. With E. hemiphloia F.v.M. 



" From E. hemijMoia it differs in the nature of its timber, oil, buds, and leaves. ... Of 

 described species it is most closely allied to E. hemiphloia and other ' Boxes ' in oil, kino, and botanical 

 characters. (Original description.) 



I agree that the closest affinity of certain specimens attributed to E. Woollsiana 

 is to E. JiemijMoia var. microcarpa, indeed that they cannot be separated. In this 

 connection compare, for the former, the illustrations referred to at p= 223, ^vith those 

 of E. hemiphloia var. microcarpa at Plate 50, Part XI, figs. 7-17. In E. hemiphloia 

 we have broad suckers and usually, almost invariably, coarser mature foliage ; paniculate 

 inflorescence, which often serves to separate it from its congeners ; fruits usually larger 

 and more ovoid. At the same time, in E. hemiphloia, through arrested growth and 

 other causes, we may have very small fruits. Mr. Cambage was alive to that many 

 years ago, for, in sending me twigs of E. hemiphloia var. microcarpa, from Mount
