Callitris calcarata, R.Br. 
Botanical Name. —Species, C. calcarata , R.Br. exMirb. in Mem. Mus. Far., xiii, 74 
(1S25). 
A tree of medium size, rarely exceeding 50 feet. 
Branchlets. —Coarse and very angular, with short internodes. “ Frequently acicular leaves on 
the lower branches.”—(Benth.) 
Male amenta. —Usually solitary, short, and compact. 
Fruit-cones. —Almost globular in shape when closed, but with a broader base, about | inch in 
diameter, the three larger valves but little or not dilated upwards, the dorsal point very 
near the end, smooth or scarcely rugose, the three smaller ones often slightly overlapping 
and the cone furrowed at junctions. Central columellas, three to five or six. 
Fertile seeds. —Dark red brown (brown madder). 
C. calcarata and C. Muelleri are often confused. In the latter there is hut one 
columella, in the former several, of irregular form. In calcarata the space between 
the leaf-scales is smaller than in Muelleri and the branchlets are much less coarse. 
C. calcarata, the Black Pine, and C. robusta, 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 foliage, while that of the 
White Pine is silvery. The cones of the Black Pine have usually stiff points on 
them ; this is only exceptionally the case with White Pine; the stalk of the fruit is 
usually slender in the case of White Pine. In the case of Black Pine the cones 
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. 
Botanical Name. — Calcarata, Latin, calcar, calcaris, a spur, in allusion to 
the points on the back of the valves. Allan Cunningham was the first to give the 
specific name (as Frenela ) in his MS. Journal, under date 25th May, 1817. He was 
then in the Lachlan district with Oxley’s expedition. 
Squamae of the strobile calcarated near the apex which is longer than C. glauca. Arbuscula, 25 feet. 
Vernacular Names. —Most commonly known as “ Black Pine,” hut also as 
“ Red Pine.” 
The Red Pine occurs on the ridges, where it is also called Mountain Pine. It is generally stunted and 
does not produce timber of any commercial value. It is also subject to dry-rot and doziness.—(Forest 
Cadet H. Swain, Cootamundra-Grenfell District.) 
The darker is called indiscriminately Red or Black Pine.—(District Forester Osborne, Cootamundra.)
