Dr. Leichhardt's specimen from ^loreton Bay, 1845, probably came from 

 further inland, for the term " Moreton Bay " would probably not be used 

 at that time in so restricted a sense as understood to-day. It is 

 labelled b}' Edward Spach and also by Brongniart as C. Hiicgclii. 



II. SYSTEMATIC. 



Callitris glauca is an evergreen tree, ■\-ar}-ing in height according to environ- 

 ment. In the far interior it is stunted in growth, whilst towards the main 

 Dividing Ranges it attains a height of over 100 feet, with a diameter from 2 to 3 

 feet. The bark is hard, compact, furrowed, but lighter in colour than that of 

 C. calcarata, R.Br., which forms with it the principal pines of the interior. 



Leaves are at first pyramidal, then decurrent in whorls of three, glaucous, 

 the internodes being shorter than obtain in most species; free end short, acute 

 the decurrent portion rounded. 



Male amenta small, two to four lines long, cylindrical, oblong, or ovoid, 

 very numerous, occurring in general, in threes at the end of the leaf series, the 

 stamens in whorls of threes, the scale-like apex concave, cordate ; anther cells 

 two to four. Female amenta solitary or not often found in clusters, situated 

 generally at the lower part of the branchlets. 



Fruiting cones globular, rarely pointed at the top, about half an inch, excep- 

 tionally three-quarters of an inch in diameter; slightly scabrous; valves six, 

 alternately large and small, the latter about a quarter less in size than the larger
