NOBTH-WESTEBN HIMALAYA ; from the .Sutlej westwards, alt. 5000-8500 ft., 

 cultivated only. DISTRIB. Wild from N. Persia westwards to S. Italy. 



A large tree, in Kashmir attaining 75 ft. and with the trunk 25 ft. in girth ; 

 branches very spreading. Leaves 6-9 in. diam., usually broader than long, base 

 cuneate at the insertion of the petiole, young woolly beneath j petiole 3-5 in. ; 

 stipules on shoots leafy and lobed. Heads 1-1| in. diarn., 2-3 on a slender peduncle 

 4-6 in. long. The P. occidentalis, L., of N. America, is not. as Brandis (1. c. 435) 

 supposes, commonly cultivated in Western Europe, where the plant so called is a-var. 

 (acerifolia) of orientalis. The true occidentalis differs in the truncate tips of the 

 ripe carpels, whence the head of fruits is smooth.
