136 ON THE EUCALYPTS OF N.S.W., PART VIII., 



E. GuNNii, Hook, f., var. acervula, var.nov. 



(Syn. E. acervula, Miq.; also E. 2^aludosa, Baker, these Pro- 

 ceedings, 1899, p. 464). 



This is E. acervula, Miq., according to specimens in European 

 herbaria. We have found it as far north as Hill Top. It was 

 called " Yellow Gum " on a label by the late Rev. Dr. Woolls 

 over 40 years ago. It has a yellowish sap-wood, and the buds 

 and general cast of the foliage are often yellow. It is also called 

 " Creek Gum." " Yellow Gum " is the district name (Goulburn 

 to Moss Vale) for rubida also. 



E. GuNNii, Hook, f., var. ovata, var.nov. 



(Syn. E. ovata, Labill. partly; E. paludosa, Baker). 



There is a form of E. Gunnii found in Tasmania, Victoria and 

 New South Wales, usually in cold and low-lying situations. It is not 

 a large tree, and is usually known as "Swamp Gum" and "Flooded 

 Gum," but also as "Broad-leaved Sally." The leaves are often 

 broad, and sometimes mucronate. Typical and conical-fruited 

 Gunnii from both Tasmania and Victoria are, however, not rarely 

 mucronate also. The operculum is often beaked, and the fruits 

 are small, conoid, and with very exserted valves. There exists, 

 however, an absolutely complete series of specimens of E. Gunnii 

 fruits from hemispherical to conical, and with sunken valves to 

 those extremely protruded. We have had these extreme forms 

 under observation for many years, and continue to hold the 

 opinion that it is impossible to separate them from E. Gu>nnii. 

 Mr. R. T. Baker has figured and described an extreme form 

 (which we have for many years noted in MS. as E. Gunnii, 

 Form 3) in these Proceedings (1899, p. 298) under the name of 

 E. cam2)hora, and further field experience only establishes our 

 conviction that it is but a variety of E. Gunnii. The tree is very 

 common in North-Eastern Victoria, and was always labelled 

 " E. Guyinii " by Mueller. 



We have E. Gunnii from the Jenolan Caves, with typical fruits 

 and leaves even broader than those of Mr. Baker's camphora.
