568 ON EUCALYPTUS GUN Nil, HOOK. F., 



collections, bears the label " E. viminalis (?)." I have not seen 

 any number attached to it. 



It is in every way identical with B. Gunnii, Hook. f. var. 

 ace7'vtila. 



Bentham (B.Fl. iii. 207) gives E. acervula, Miq., as a synonym 

 of E. itiacrorrhyyicha, F.v.M. This mistake has probably arisen 

 through some confusion with E. acervula, Sieb., although Bentham 

 mentions " non Sieb." E. acervula, Sieb., is a Stringybark [E. 

 eugenioide^, Sieb.) like E. macrorrhyncha, F.v.M. 



Mr. Rodway, one of our best botanists, also confuses E. acer- 

 vula, Miq., with E. acervula, Sieb., in the following passage, 

 through not having seen the types, or perhaps by following 

 Hooker (Fl. Tas.), whose E. acervula, Sieb., is wrong. ^^Eucalyp- 

 tus acervula, Sieb. This is a ver}' common Tasmanian Gum, 

 and though in some respects nearly related to E. Gunnii, is 

 consistently distinct. Its habit and bark, its thinner undulate 

 leaves and numerous flowers, its peculiar turbinate fruit, with 

 protruding valves, make it very distinct, yet Mueller not only 

 combines it in his Eucalyptographia with E. Gunnii, but rejects 

 the type established by Hooker of that species and replaces it 

 with a plate of the typical E. acervula, Sieb." (Proc. R.S. Tas., 

 1898-99, p. 104). The reference to the Eucalyptographia plate 

 is not quite accurate. The main twig and the cluster of buds at 

 the left hand top corner are both var. acervula. The rest of the 

 illustrations are typical Gunnii or nearly so. On the mainland, 

 at all events, E. Gunnii runs into var. acervula, and the evidence 

 I will presently adduce shows, in my opinion, that the same is 

 the case in Tasmania also. 



8. E. acervula. Hook, f., non Sieb. (Fl. Tas. i. 135, as E. acer- 

 vula, Sieb.). 



I have examined the following specimens of Hooker's types of 

 the above : — 



1088, R. Gunn. Herb. Cant, ex herb. Lindl. In bud and 

 flower. 



1089, R. Gunn. Ralph's Bay, Y.D.L., 1842. In Herb. Cant, 

 ex herb. Lemann and herb. Lindl.; in plump bud and early fruit.
