PINACE^ 443 



Pinus pumila, Kegel. 

 Dwarf Siberian Peste. 



Pinus Ccinbra, var. pumila, Pallas ; P. Cembra, var. pygmrpa, Loudon ; 

 P. inandsl Ulrica, Murray (not Ruprecht) ; P. pygmnea, Fischer. 



A slirub more or less prostrate in habit, but sometimes 10 ft. 

 high, with branchlets similar to those of P. Cembra. Winter buds 

 narrowly conic, about \ in. long, with a sharp-pointed apex, and 

 closely pressed scales. Leaves in fives, resembling those of P. 

 Cembra, but shorter and more slender, l|-2 in. long, entire or 

 with faintly toothed margins. Cones ovoid, very shortly stalked, 

 never opening to liberate the seed ; about 2 in. long, orange- 

 brown when ripe ; scales few, about ^ in. broad, with a dark- 

 coloured, triangular, reflexed tip. Seeds about \ in. long, pear- 

 shaped, wingless. 



This plant is distinguished from P. Cembra chiefly by its 

 shrubby habit, shorter leaves and smaller cones and seeds, but 

 its general characters are so near those of P. Cembra that it ought 

 probably to be regarded as a dwarf form of that species. 



Native of E. Asia, occurring in Kamtschatka, Siberia, Amur- 

 land, Saghalien, Kurile Islands, and Japan. It usually grows 

 in the coldest and most exposed situations, forming dense thickets 

 on the wind-swept plateaux or on mountains near the snow line. 



P. pmnila has no commercial value, for the wood can only be 

 used locally as firewood, and the seeds, owing to their small size, 

 are of little use for food. It is rarely seen in gardens, but young 

 plants are growing at Kew. Loudon mentions a specimen at 

 Dropmore, which though 20 years old was in 1837 only 6 in. high. 

 By 1866 it had increased its height to 8| in. The tree was 

 reintroduced by Admiral Sir Lewis Clinton-Baker from Nikko, 

 Japan, in 1909, when two specimens from that locality were 

 planted at Bayf ordbury. ^ The rockery forms a good place for 

 this bush.

Pinus pungens, Lambert. 

 Prickly Pine. 



Pinus Tseda, Lambert in part (not Linnaeus) ; P. montana, Noll (not 

 Miller). Hickory Pine ; Southern Mountain Pine ; Table Moimtain Pine. 



A tree 40-60 ft. high and 7-9 ft. in girth, or sometimes small 

 and stunted with a low flat head. Bark of old trees about 1 in. 

 thick, reddish brown, scaly. Young shoots green at first, after- 

 wards reddish brown, without down. Winter buds cylindrical, 

 short-pointed, about f in. long, resinous. Leaves in pairs, per- 

 sisting 3 years, crowded on the branches, dark green, rigid, 

 twisted, 2-3 in. long, margined by rudimentary teeth, apex 

 sharp-pointed, stomatic lines numerous and prominent on both
