Callitris Tasmanica, Baker et Smith1) (Frenela rhomboidea, R. Br. var. Tasmanica, Benth.) occurs in Tasmania, also locally in Victoria and New South Wales. In Tasmania it is known as Oyster Bay pine.
The oil from the leaves distilled in March with a yield of 0,14 p.c and in June with a yield of 0,208 p.c, had the following properties: d15o 0,8976 and d22o 0,9036; aD 4-1,0° and - 5,8°; nD25o 1,4738 and nD15o1,4739; ester content (hot) 59,95 and 62,75 p.c, (cold) 59,91 and 62,2 p.c, computed as C10H17Ococh3: insoluble in 10 vol. of 70 p.c alcohol, soluble in 1 vol. and more of 80 p.c. alcohol. The oil consists to the extent of 70 p.c. of geranyl-acetate and free geraniol. Upon fractionation the presence of the following constituents was ascertained: d-a-pinene, probably mixed with /-a-pinene, (d23/15o 0,857; aD +9,9°; nD24o 1,4706; m. p. of nitrosochloride 107 to 108°, of benzylamine base 122 to 123°), /-limonene, dipentene (m. p. of tetrabromide 118°). In the saponification liquid acetic acid only was found. In addition the oil contained a small amount of phenol which probably is identical with that found in the oil of Callitris gracilis.
