626 ON THE EUCALYPTS OF N.S.W., PART VI., 



The late K. H. Bennett sent this species from Ivanhoe, via 

 Hay, under the native name, " Tangoon " with tiie note that " this 

 is our largest ti'ee, often attaining a height of 70 to 80 feet, with a 

 diameter of 4 feet. It is the principal tree used Iw the blacks 

 for the extraction of water from the roots. While indubitably 

 £1. microtheca, it resembles the broad-leaved forms of E. largifiorens 

 The flowers are large, the leaves have a yellowish cast, and are 

 I or 1 inch broad, by 2| inches long, having quite a different 

 appearance from normal microtlipxa. In fact remarks in regard to 

 the variation in size and shape of leaves of E. largifiorens largely 

 apply to E. 7]ticrotheca also. 



" Coolibah " or " Flooded Box " is found on all Gulf (of Carpen- 

 taria) waters, often in flooded ground, of a crooked growth, about 

 30 feet high (E. W. Palmer, Proc. H.S.KS.W. 1883, p. 106). 

 Mr. Palmer's specimens came from the Flinders, and were named 

 E. microtheca by Baron von Mueller. Following are some 

 additional particulars furnished in a letter from Mr. Palmer to 

 the late Rev. Dr. Woolls, whom we had asked to enquire as to 

 the differences between the Coolibah and Goborro (E. largifiorens): 



" The Coolibah generally is of a crooked growth, but now and 

 again, in favoured localities of deep soil, it is straight enough to 

 make stockyard posts of about 10 to 12 inches in diameter, and 

 8 or 10 feet long. The wood is excessively hard and inlocked; 

 impossible to split, and hard to bore through. It requires 

 especially good augers to bore it. The bark is rough and scaly, 

 and the branches are not smooth and white. The colour of the 

 wood is very dark brown. I have seen the Flooded Box of the 

 Darling (i.e., largijioreas), but ne\'er examined it closely. 

 Althouo-h it looks like our Flooded Box of the Flinders there is 

 a difference. The Goborro seems smaller, the bark is different, 

 and the branches are smooth and white in the bark." 



Goborro {E. largifiorens) and Coolibah {E. microtheca) are 

 frequently confused. If fruits be available the hemispherical, 

 very open fruit, not above 2 lines diameter, the valves protruding, 

 of the latter at once distinguishes them; while the anthers of the 

 latter open in slits, and of the former in pores. There are other
