646 CONIFERZ. [Agathis. 
The kauri-pine, too well known to require any detailed account. Timber 
not excelled by any other for the variety of uses for which it is adapted, and 
remarkable for its strength, durability, and the ease with which it is worked. The 
resin, or ‘‘ kauri-gum,’’ so important for varnish-making, is still dug in large 
quantities on the sites of previous forests, or obtained from those still living.

Usually tall trees. Leaves opposite, small and scale-like’ quad- 
rifariously imbricate, either all equal and decussate, or flattened 
on the branchlets, the lateral larger and keeled, those on the upper 
and lower faces of the branchlets smaller and flat. Flowers 
moncecious or dicecious; males terminal, solitary, oblong or ovoid 
or almost globose, consisting of a staminal column sessile within 
the uppermost leaves and bearing several or many decussately 
placed anthers; connective scale-like, ovate, subpeltate; anther- 
cells usually 4, pendulous. Female cones oblong or ovoid, terminat- 
ing short branchlets ; scales 4 or 6, decussately opposite, the lowest 
pair smallest and sterile, the second pair with 2 erect collateral 
ovules at the base of each scale, the third pair when present sterile 
and connate. Scales of the mature cones persistent, gaping, in- 
durated, mucronate or horned at the back towards the tip. 
Seeds solitary or rarely 2 at the base of each fertile scale, com- 
pressed, unequally winged. 
A small genus of 9 species, with a very singular distribution, 1 being found 
in California, 2 in Chili, 2 in New Zealand, and 1 each in New Caledonia, New 
Guinea, China, and Japan.

1. L. Doniana, Endl. Syn. Conif. 43.—A tall forest-tree 30 to 
70 ft. high or more, with a narrow tapering head; trunk 2-4 ft. 
diam.; bark stringy, falling off in long ribbons. Branchlets dis- 
tichous; of young trees vertical, much flattened and compressed, 
11in. broad; of old trees horizontal, less compressed, but not 
obviously tetragonous, ~4-4in. broad. Leaves quadrifarious, the 
lateral larger, especially on young trees, where they are often +in. 
long, sheathing and connate at the base, spreading, acute; those on 
the upper and lower faces of the branchlets ;,—,4,in. long, tri- 
angular, appressed to the branch. Male flowers about +in. long, 
hardly broader than the branch; anthers 8-12; connective thin, 
ovate, subpeltate. Female cones ovoid, about 4in. long, woody; 
scales 4, spreading, each with a sharp curved spine at the back. 
Seeds 2 to each cone.—Hanab. N.Z. Fl. 256; Kirk, Forest Fl. t. 82.
