Material for distillation was also received from Armidale, N.S.W., in 

 June. 11)07. The yield of oil was 0-94 per cent. The crude oil was red in colour, 

 and had an odour similar to those of the cineol-pinene oils containing aromadendral. 

 The oil was quite in agreement with that from Marulan, above, and contained 

 the same constituents in practically the same amounts, except that it was a 

 little richer in cineol. 



The crude oil had specific gravity at 15 C. = 0-9075 ; rotation a D + 1-5° ; 

 refractive index at 20 = 1-4679, and was soluble in i| volumes 70 per cent, 

 alcohol. 



The cineol was determined by the phosphoric acid method in the crude 

 oil ; the result was 57 per cent. 



95. Eucalyptus cosmophylla. 



(F.v.M., in Trans., Vict. Inst., 32, 1S55.) 



Systematic. — A shrubby tree, though sometimes found up to 50 feet in 

 height. Bark smooth (decorticating in thin flakes or sheets). Abnormal leaves, 

 broad, oval-cordate, sessile, crenulate, scabrous, branchlets much flanged. 

 Normal leaves ovate-lanceolate, acuminate, pale green on either side; intra- 

 marginal vein well removed from the edge, lateral veins generally at an angle of 

 45 with the midrib. Buds large, usually three, sessile or almost so, common 

 peduncle flattened; calyx tube conical, rough, often ridged, about 5 lines long; 

 operculum almost hemispherical, shortly pointed. 



Fruit.— Semi-ovate, almost hemispherical, occa- 

 sionally ribbed; rim bevelled or flat, 

 outer edge sometimes forming into a 

 flange; valves depressed or slightly ex- 

 serted ; about 6 lines long and 6 lines 

 broad. 



In the larger form the fruit resembles those of 

 E. longifolia, but the hemispherical more closely 

 perhaps those of E. ovata, Labill, Western Aus- 

 tralia, collected by Mueller. 



Habitat. — Kangaroo Island and ranges near Adelaide, South 

 Australia. 



REMARKS. — This species is endemic to South Australia, and is easy of determination, both in the herbarium 

 and field, by its specific characters- 



ESSENTIAL OIL.— Material consisting of the leaves and terminal branch- 

 lets for distillation was received from the Conservator of Forests of South 

 Australia, Mr. Walter Gill. The material was collected in December, 191 1. 

 The yield of oil was 0-62 per cent. The crude oil was light orange-brown 

 in colour, with an odour indicative of an oil belonging to the cineol-pinene group, 

 with a secondary one suggestive of the aldehyde aromadendral. The presence 

 of volatile aldehydes was particularly marked. The slight laevo-rotation of the
