Baker, R. T. and H. G. Smith, The Pines of Australia, Part L, 

 fAbstr. Proc. roy. Soc. N. S. Wales, p. III— V. Aug. 5. 1908.) 



The Australian Pines, Callitris, form a distinguishing feature of 

 the landscape in various parts of the Continent. In order to inves- 

 tigate their commercial possibilities, a research has been in progress 

 now for some years at this Museum, and during this period a very 

 large amount of useful data has been accumulated which it is pro- 

 posed to publish from time to time. In it is given a füll account of 

 ihe botany and chemistry of the 'White or Cypress Pine,' Callitris 

 glauca, a species that has the largest geographical ränge of the 

 genus, occurring in nearly all the States of Australia. It was one 

 of the first collected, being obtained by Robert Brown in 1825, 

 the original specimen being still in existence at the British Museum. 

 He bestowed the specific name on account of the bluish colour of 

 the leaves — a feature that easily distinguishes it from other Pines. 

 The systematic side of the species is fully dealt with. In addition to 

 the morpholog}^ of the species, micro-sections of the leaves, tim.ber 

 and bark are also full)^ described and illustrated, and some new 

 and interesting facts are advanced in connection with these parts of 

 the tree. A theory is advanced accounting for the remarkable shape 

 of the leaves of the Callitris. The timber sections brought out the 

 fact that our Callitris are of some antiquity and in this respect are 

 allied to fossil Conifers in North America. Results of tested spe- 

 cimens of the timber are given. No less than seven samples of the 

 volatile oil of the foliage of this species have been investigated , 

 obtained from widely separated localities in New South Wales.
