A tree 60 ft. high with horizontal branches. Barh thin, 

 smooth and greenish. Young shoots, green, often covered at 

 first with small glands. Winter buds cylindrical, blunt, sUghtly 

 resinous. Leaves in fives, persisting 2-3 years, spreading or 

 drooping, usually sharply bent |— | in. from the base, 4-6 in. long, 

 margins finely toothed, apex pointed, under surface green, two 

 upper surfaces white with stomatic lines, resin canals median ; 

 basal sheath and scale leaves deciduous. Cones sub-terminal, 

 on stalks 1 in. or more long, 1-3 together, cylindrical, tapering 

 to a rounded apex, 4-7 in. long 2-3| in. wide, erect at first, 

 pendulous during the second year ; scales thick and rigid, 

 woody, resinous, about IJ in. long and 1 in. wide, broadly 

 triangular, the concealed portion reddish brown, the exposed 

 part j^ellowish brown and rounded at the apex, which is sometimes 

 shghtly reflexed. Seeds wingless, |— | in. long, liberated soon 

 after ripening. Male flowers smaller, more loosely arranged and 

 extending much further along the shoot than in P.. excelsa. 



P. Armandi closely resembles P. excelsa in foliage, but the 

 distinct bend near the base is characteristic of the former. The 

 young shoots of P. Armandi are usually more or less covered 

 with fine glands, whilst those of P. excelsa are glabrous. The 

 cones of the two species are quite distinct, those of P. Armandi 

 being much stouter and the scales wider than in P. excelsa. 



The species is wild in the mountains of W. China, where it is 

 widely distributed, and usually found in rocky places, rarely 

 forming pure forests. It was originally discovered by Pere 

 David in 1873, south of the Yellow River in Shensi, and subse- 

 quently by other travellers in Yunnan, Hupeh, and Szechuen, 

 and more recently in Formosa. 



It grows rapidly at Kew in light, well-drained loam under 

 similar conditions to P. excelsa. Trees 20 years old cone freely, 

 and some of the seeds are fertUe. 



The largest trees at Kew (February 1923) are 37 ft. and 35 ft. 

 high respectively, and the former is 2 ft. 3 in. in girth at 5 ft. 

 above the ground.
