582 ON EUCALYPTUS GUNNIl, HOOK. F., 



In dry situations it is often difficult to discriminate between it 

 and var. 7'uhida. I have, on several occasions, had tall trees cut 

 down in order to discover which form they were. 



The term " Spotted Gum " appears characteristic enough in 

 many places, but we have intermediate forms. It is called 

 " Bastard White Gum," "Spotted Gum," "Cabbage Gum," and 

 a variety of names. 



It is found in many parts of the State and Victoria, particu- 

 larly in cold, mountainous districts, usually on hill sides and less 

 frequently by the side of streams. In its typical form it occurs 

 on dry slopes and ridges ; in moist situations it approximates to 

 the normal form, and hence usually escapes separate notice. 



By the non-botanist the Spotted- Gum-form {i.e., that growing 

 in dry situations) is usually confused with the common White 

 Gum {E. hcemastoma), but it belongs to the Parallantherae. Mr. 

 R. H. Cambage has obligingly written the following comparison 

 of the two trees, as he knows them, from Mt. Victoria to Burraga, 

 Ophir, Orange, &c. He calls it " White Brittle Gum," and 

 E. hcemastoma, var. micrantha, "Red Brittle Gum." 



" This tree has various names in different localities. At 

 Wiseman's Creek, near Bathurst, it is called ' White Cabbage 

 Gum,' while at Ophir, near Orange, some miners give it the name 

 of ' Spotted Gum,' as it loses its bark in small patches, which 

 have a yellowish tint, but are not so distinctive as E. tnacrOata. 

 ' White Brittle Gum' is a very general name. 



" By a casual observer this tree would be confused with 

 E. hcemastoma.^ and in general appearance it very much resembles 

 it. When seen growing together it will be noticed that the 

 White Brittle Gum is ivhiter in the bark than E. h(eniasioma, the 

 former often being covered with a white powder ; hence another 

 name for it is ' White Floury Gum,' which I have heard used. 



"The fruits of White Brittle Gum are more sessile and domed. 

 The leaves are not so brittle as those of E. hcemastoma, and the 

 difference can be detected by biting them. I have seen this 

 experimented on by mixing the leaves of both trees and then 

 having them correctly separated in this way as a test.
