Linncear The word cladocalyx is from Mados a branch; corynocalyx means club- 

 shaped calyx (or bud or fruit). " The specific name is derived from the calyx, somewhat 

 club-shaped while in its unexpanded state (" Eucalyptographia"). 



No doubt corynocalyx is more descriptive than cladocalyx, but the fact that an 

 inappropriate name was given by a " clerical error" cannot be permitted to add to 

 the confusion. Let us get to a firmly based nomenclature as soon as we can, for count- 

 less botanists will follow us, and it is for them we are building- as well as for our con- 

 temporaries. 



Bentham, B. Fl. iii, accepted E. corynocalyx without comment, and Mueller 

 ("Eucalyptographia") adopts his own second name, E. corynocalyx. The species is 

 figured by Mr. J. Ednie Brown in his " Forest Flora of South Australia." 



The name " Sugar Gum" has been applied to this tree (I do not know by whom 

 originally, although it first came into use at Wirrabara Forest, S.A., as Mr. Walter Gill 

 told me, but certainly Mr. J. Ednie Brown made it popular), because the foliage is eaten 

 by stock, and Mr. Brown quoted E. Gunnii as possessing similar properties. At the 

 same time, in the " Forest Flora of South Australia," in which he made the statement, 

 the tree he figured as E . Gunnii Hook f., is E. ovata Labill. , 



Mr. J. E. Brown, in evidence before the Victorian Vegetable Products Commission, 

 1889, calls this the most valuable of South Australian timbers, and (in that State) just 

 as rapid of growth as E. globulus , the timber more durable and valuable than that of 

 E. rostrata, and capable of resisting the white ant better than E. marginata. It grows 

 particularly well on limestone country, and is one of the most ornamental of South 

 Australian Gums. Mr. Brown showed trees at four years about 20 feet high; they were 

 planted out when about 4 inches high. While undoubtedly a valuable South Australian 

 timber, it may be that the comparisons with other timbers may require revision.
