256 LIBOCEDRUS TETRAGON A. 



pair boat-shaped, conduplicate and sharply keeled ; the dorsiventral pair 

 obovate, concrescent and glandular. Staminate flowers four-angled, 

 composed of eight ten stamens in decussate pairs. Strobiles conic- 

 cylindric, about an inch long, consisting of six ligneous scales, the 

 lowermost pair minute and reflexed, the middle fertile pair broadly 

 oblong, the uppermost pair narrowly linear. Seeds one to each fertile 

 scale, with an obovate-oblong, oblique wing.

This species was discovered in the Chinese province of Yun-nan by 

 Dr. Anderson, who was attached as medical officer and naturalist to 

 an expedition under Major Sladen, 1870 1871. The discovery was 

 a remarkable one, as it extended the distribution of the genus into 

 a region far remote from the species inhabiting California, Chile and 

 New Zealand. It has since been gathered in the same province by 

 Dr. Henry, and by the Veitchian collector, E. H. Wilson, but the 

 attempts to introduce it into British gardens have thus far been 

 unsuccessful. 



Libocedrus tetragona. 



A tree of variable height and habit, according to situation and 

 environment ; at its greatest development attaining a height of 60 80 

 feet but frequently much less ; at its highest vertical range reduced to 

 a dense bushy shrub. In the arborescent form the primary branches 

 are stoutish, spreading or ascending, forming a conical or sub-pyramidal 

 crown. In Great Britain of shrubby habit, 9 12 feet high, with 

 erect or sub-erect branches densely ramified. Branchlets tetrastichous 

 (four - ranked), the youngest shoots very short. Leaves on the axial 

 growths broadly ovate, acute, adnate except at the tip, persistent four 

 five years ; on the lateral shoots ovate-lanceolate, subtrigonal, acute, 

 spreading, grass-green with a greyish triangular . stomatiferous area on 

 the flat dorsal side. Staminate flowers not seen. Strobiles subtended 

 at the base by four subulate acute bracts, and composed of two 

 decussate pairs of scales, each with an incurved mucro at the back, 

 and of which the broader fertile pair bear one two winged seeds.

Libocedrus tetragona inhabits the western slopes of the Andes of 

 southern Chile, but very little is known of its actual distribution 

 over that region, and the little that is known is confused by 

 being mixed up with Fitzroya patagonia. Its northern limit may be 

 placed at about the 35th parallel of south latitude, whence it spreads 

 southwards to beyond the 45th parallel, and as some authors state, 

 to the Straits of Magellan ; but from Valdivia southwards it is either, 

 associated with, or its place is wholly taken by the Fitzroya which is
