" Yellow Gum, on flats, Bowral to Goulburn " (W. Woolls), 50 or 60 feet. 



" Swamp Gum." A small mallee-like tree, 10-15 feet, rough bark, stooling, 

 forming clumps, growing in permanent water. Juvenile leaves ovate to orbicular. 

 Mature leaves not long and of medium width. Buds in stellate umbels ; opercula often 

 very pointed and pale coloured. Fruits conoid to subcylindrical, valves exserted. 

 Paddy's River, Wingello (A. Murphy, J. L. Boorman). Specimens like these show 

 absolute transit between E. ovata and E. camphora. (See figs. 8 and 9, Plate 114.) 



Bendooley, Berrima (J.H.M. and J. L. Boorman). 



" Flooded or Ribbony Gum," Shepherd's Swamp, Hill Top (J.H.M.) ; The Peaks, 

 Yerranderie (R. H. Cambage). 



Western localities.— On the Lowther Road, Mt. Victoria, we have interesting 

 specimens collected off the same tree, the series being most instructive. A pendulous 

 Ribbony Gum. Juvenile leaves, broadish. Fruits conoid and domed; shiny bud, 

 multiflowered ; a combination of ovata and maculosa. Contemplation of a tree like 

 this shows how difficult it is to separate ovata and maculosa. White Gum specimens 

 from Mt. Victoria have the fruits somewhat like maculosa, but not so domed, and 

 more conoid. The fruits also have some resemblance to rubida, but are multiflowered. 



At Fairy Dell and other parts of Mt. Victoria there is "■ Swamp Gum " in 

 abundance, with undulating leaves, which are sometimes very long, and with broad 

 suckers. Buds shiny. The fruits in the unripe state have the truncate appearance 

 so commonly seen in Victoria, South Australia, and other parts of New South Wales. 

 The resemblance to maculosa is obvious. 



' White Gum." Shiny, smallish, nearly sessile fruits, nearest to acervula. Mt. 

 York (J.H.M.). Smooth-barked tree, broad juvenile leaves. Shiny buds, multi- 

 flowered. It is E. ovata, yet in the shape of the fruits showing undoubted affinity to 

 E. maculosa. Mt. Wilson (Jesse Gregson, J.H.M.). 



AFFINITIES. 



Its affinities are with E. Gunnii Hook. f.,and its relations (E. maculosa R. T. Baker, 

 E. rubida Deane and Maiden), and I have so abundantly brought this under notice that 

 there seems but little more to be said on this head. 



1. With E. Gunnii Hook. f. Hooker himself in describing his E. acervula (ovata) 



says "the foliage is that of E. Gunnii^ and as he originally described 



E. Gunnii, his opinion was worth something. Rodway says : 



Eucalyptus acervula, Sieb. (should be Hook, f., non Sieb.). This is a very common Tas- 

 manian 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. (Kodway in Proc. R.S. Tas., 1898-99, p. 104.)
