Callitris calcarata, R.Br. 



C. calcarata and C. Muelleri are often confused. In tlie. latter there is^ 

 but one columella, in the former several, of irregular form. In calcarata 

 tlic space between the leaf -scales is smaller than in j\tuelleri and the branch- 

 lets are much less coarse. 



C. calcarata, the Black Pine, and C. rohusta, the White Pine, are often 

 confused in general descriptions, and the following notes bring out their 

 chief points of difference. The Black Pine has usually bright green folia!,\v 

 a; hile that of the White Pine is silvery. The cones of the Black Pine hav(^ 

 usually stiff points on them; this is only exceptionally tlie case with Wliite 

 Pine. The stalk of the fruit is usually slender in the I'ase of White Pino. 

 In the case of Black Pine the (-ones persist on the old wood for many 

 years ; White Pines have usually many fallen cones under each tree. Usually 

 the seeds of the Black Pine are reddish-brown in colour, while those of the 

 White Pine are of a pale brown.
