452 ON THE EUCALYPTS OF NEW SOUTH WALES, 



than the latter; the timber also lighter in colour. The branches 

 have smooth tips. 



Timber. — Pale, not brown wheii fresh like E. hemiphloia, 

 inlocked, very tough, evidently an excellent timber. The rougher 

 bark falls off in patches, leaving box -like but less rough patches 

 underneath. Again, these less-rough patches become darker and 

 more rough, and this process is repeated ad injinihwi. 



Kino. — On a tree being cut into a pocket of kino of a treacly 

 consistency and colour exuded, which in a few hours dried into a 

 hard, dark brown mass, which broke with a bright fracture. It 

 is all but insoluble in alcohol and soluble in water, forming a 

 rich tawny solution with deposition of gum on addition of alcohol, 

 and thus belongs to Maiden's gummy group of kinos. 



Sucker leaves. — Narrow-lanceolate, cordate and clasping at the 

 base, strictly opposite, markedly paler on the under surface. 



The sucker foliage of E. goniocalyx presents considerable 

 similarity to that of E. quacb'angulata, differing chiefly in the 

 greater breadth and shorter length of the former. 



The sucker stems are brown (commonly chocolate-brown) and 

 usually square in section. Not only is the young stem quad- 

 rangulate, but it is even winged, and this is so marked a character 

 that the name alata would probably have been chosen had this 

 name not been preoccupied. 



Other instances of quadrangular stems in Eucalyptus are : — 

 E. tereticornis (apparently not common), E. globulus, and E. 

 Maideni. 



The E. elata of Dehnhardt has also quadrangular stems. It 

 has been placed under E. viminalis by Bentham, but that is an 

 obvious error, and its position must remain in doubt until adequate 

 material be available. Mueller [Eucalyptographid) suggests E. 

 amygdalina, with which we also cannot concur. 



Mature leaves. — Branchlets angular, lanceolate or narrow- 

 lanceolate, slightl}' falcate, usually 4 to 6 inches long, scarcely 

 paler on the under surface. 



The margin usually sinuate, jagged or remotely denticulate. 

 Venation conspicuous on both sides, the intra-marginal vein con-
