the sandstone, the Bloodwood requires another condition, and 

 that is warmth, for while the llawkesbui-y Sandstone extends 

 from Sydney across the Blue Mountains to Lithgow, H. coryni- 

 bosa finds, at about 3,000 feet, that the climatic effect domi- 

 nates over the consideration of geological formation, and the 

 species becomes rare after the town of Wentworth Falls is 

 passed. The timber of this tree, though containing a number 

 of gum-veins, is well known to possess remarkable qualities 

 for lasting a long time in the ground. 



E . Consideniana may be seen on the top of the mountain, 

 on Hawkesbury Sandstone, just before the descent into Bur- 

 ragorang is commenced, and without some inspection is not 

 easily identified. It may be said to have the grey fibrous 

 bark of E. 2}i2}erit(i (Sydney Peppermint), and the fruits 

 (almost) of E. Sieberiana (Mountain Ash). Its juvenile foli- 

 age is narrower than that of either, and is arranged vertically 

 like that of the latter and unlike that of the former, which is 

 disposed horizontally.* So far it has always been found 

 associated with E . jjiperita and E. Siebei-iana, flowering early 

 in November or just after the latter and before the former ; 

 and the suggestion that it may have originated as a hybrid 

 between these two species, though extremely difficult of proof, 

 may possibly be correct. f 



E . Consideniana seems to have no definite vernacular name, 

 probably owing to the difficulty of its absolute identification 

 by bushmen, but is varioiisly referred to as Peppermint or 

 Messmate, though both of these names are more generally 

 applied to other trees. It is known to occur near Gosford, 

 and on the mountain-top just north of Newnes on the Wolgan 

 River ; and extends southerly from these points, occurring 

 intermittently, as far south as Ulladulla, being found on the 

 coast at the latter place, and to within 100 feet of the top of
