PINACEiE 301 



D. Lateral leaves much longer than the median leaves. 



Median leaves minute, rounded at the apex, with a 

 conspicuous gland. — L. chilensis. 



Median leaves ovate, acute, mucronate, scarcely glan- 

 dular. — L. Do7iiana. 



Median leaves with a short triangular point ; lateral 

 leaves recurved and blunt at the apex, margins 

 strongly recurved. L. austro-caledonica. 



Libocedrus arfakensis, Gibbs.^ 



A tree 90-115 ft. high with a shapely bole and more or less 

 conical head of branches in sheltered forests in New Guinea. 

 Bark red and scaly. Branchlets articulate. Leaves of juvenile 

 plants light green up to f in. long, widening from the base up- 

 wards, attaining a width of about j, in. below the long, slender, 

 spreading, apical point ; the lateral pair larger than and almost 

 overlapping the facial pair ; leaves of mature plants dark green, 

 shorter, narrow at the base, broad towards the apex which 

 terminates in a short, blunt, non-spreading point. In some cases 

 mature leaves, particularly on fruiting shoots, are small and scale- 

 like. The narrow base and wide apex of the lateral leaves give 

 the shoot its curious jointed character. The male flowers are 

 about f in. long from the points of short shoots. Female flowers 

 appear on different branches of the same plant, and the cones 

 are composed of 4 small pointed scales. 



Native of the Arfak Mountains of New Guinea at elevations 

 of 5,500-8,000 ft. 



Libocedrus austro-caledonica, Brongniart and Gris. 



A small symmetrical tree, never more than 20 ft. high, of 

 narrow pyramidal outhne, the branchlets Selaginella-like in 

 appearance. Leaves arranged as in L. Doniana, but larger, the 

 lateral pairs much larger than the median pairs, thick in texture, 

 closely pressed and overlapping, the apex blunt and recurved, 

 margins strongly recurved ; median leaves ending in a short, 

 triangular blunt point. Cones not seen. 



Native of New Caledonia. Not in cultivation.

Libocedrus Bidwillii, J. D. Hooker. 



Pahautea. 

 Cedar. 



A tree usually below 70 ft. high, resembling L. Doniana, from 

 which it differs chiefly in its smaller size, smaller leaves and cones, 

 and in the four-sided character of the ultimate branchlets. Cones
