EUCALYPTUS. 261 



in South Australia, Victoria and Xew South Wales. Mueller 

 found in 1000 lbs. of branches with about 500 lbs. of leaves, 112J 

 ozs. of essential oil. Bosisto states that 100 lbs. of leaves from trees 

 in elevated situations yielded 4 ozs. 13 drs. of an oil of sp. gr. 0"922, 

 while the yield from the same quantity of leaves in low, swampy 

 situations w^as only 5h drs. of oil with sp. gr. 0-899. It is bright 

 yellow in colour with a greenish shimmer and an aromatic 

 camphoraceous taste. Boiling point between 157^-199^ C. 



E. Planchoniana, Mueller. This species is of limited occurr- 

 ence and found in northern Xew South AVales and southern 

 Queensland. The odour of this oil is described as peculiar, allied 

 to citronella, but differing from it. Fresh leaves yield, according 

 to Staiger, O'OG per cent. Sp. gr. 0'915. It has been suggested as a 

 soap perfume. 



E. salubris, "The fluted or gimlet gum," so called in allusion to 

 the appearance of the stem. The extraordinary abundance of oil 

 in the leaves, approximately 4 per cent, in the fresh foliage, points 

 this species out as the leading one in Western Australia for oil 

 distillation.* Maiden makes no mention of its properties. 



E. leu coxy I on, Mueller. Known in various localities as 

 " Boxwood " or " Mountain Ash " (from some distant resemblance 

 to the appearance of the European Mountain Ash), forms a large 

 tree in the forests on the mountains in the south and east of 

 Victoria. It is also found in 'New South Wales, Queensland, and 

 in South Australia, near Spencer's Gulf. Bosisto states the yield 

 of oil from 100 lbs. of leaves to be 16 ozs. 7 drs., or over 1 per 

 cent., but observes that the leaves were heated and part of 

 the oil was lost. Sp.gr. 0-923, boiling point 155^-178^ C. Odour 

 and taste are said to resemble those of oil of K oleosa (above 

 referred to as E. cnerifolia). 



E. longifolia, Link., is found in iSTew South Wales to Port 

 Jackson, and in Victoria, the eastern part of Gipp's Land. The 

 oil is said to have an aromatic, cooling taste, and ethereal 

 camphoraceous odour. Sp. gr. 0*940, boiling point 194^-215° C. 

 According to Maiden the yield from 100 lbs. of leaves that had 

 suffered in transport amounted to 3 ozs. 3 J drs. Bosisto considers
