AFFINITIES. 



1. E. eapitellata, Sm., and E. macrorrhyncha, F.v.M. 



In " Eucalyptographia " (under E. santalifolia) Mueller has drawn attention 

 to the resemblance of the fruits of E. santalifolia [diversifoUa) to the species 

 named. The resemblance is there, more particularly between the fruits with the 

 dome-shape and those of E. macrorrhyncha. Mueller also deals at greater 

 length with the relations to E. eapitellata. I propose to deal with these affinities 

 when treating of E. eapitellata and E. macrorrhyncha. 



2. E. Planehoniana, F.v.M. 



The buds alid coarse fruits of this species somewhat resemble those of the large 

 fruited (Victorian) form of E. diversifoUa, but the valves of E. Planchoniatia are 

 more sunk, and the leaves usually thinner and larger. 



3. E. coceifera, Hook., f. 



The foliage and the immature fruits of the two species resemble each other 

 somewhat. 



4. E. strieta, Sieb. 



Miquel, in drawing attention to the affinity of the form (var. ?firma, see p. 200) 

 of E. santalifolia to E. stricia, indicates the affinity of the two species. Certainly 

 the leaves are remarkably similar, but the buds of E. strieta are more clavate, and 

 the fruits smaller and more constricted at the orifice. 



5. E. obliqua, L'Herit. 



A. " S. A., Hills, near Guichen Bay, Marble Range and Venus Bay, F. Mueller," 

 — (Herb. F. Mueller and Herb. Sonder.) " This is now reduced by F. Mueller to a 

 form of obliqna." — (Bentham, B.Fl. iii, 206, under E. santalifolia.) 



B. a-pecimens lahcWed " Encalypttts fab?'orvin, Schldt., Port Lincoln scrub, 

 legit Carl Wilhemi, exam. Dr. Ferd. Muellei'," in Herb. Vindob, are E. diversifoUa, 

 Bonpl. 



Different specimens attributed to E. fahrorxm, Schlecht., seen by me, are 

 referable to E. obliqua, L'Herit. (see p. 60, Part II), and also to E. piltilaris, Sm., var. 

 Muelleriana, Maiden {see p. 10, Part T), and, perhaps, even to the Victorian and 

 South Australian form of E. eapitellata, Sm. More field work requires to be done 

 in South Australia and western Victoria to define the relations between E. diversifoUa, 

 Bonpl., and the other species named.
