P. densata Masters) ; valley of Tung River, around village of Moshi- 

 mien, alt. 1100 m., October 1908 (Nos. 1398, 2504; tree 10-15 m. tall, 

 girth 1-2 m.) ; 20 kilometers north of Tachien-lu, alt. 2800-3300 m., 

 October 1908 (No. 1397, 2502; tree 6-20 m. tall); 16 kilometres west 

 of Tachien-Iu, around hamlet of Cheto, alt. 3300 m., July 1908 (No. 

 905; tree 8-25 m. tall, girth 0.6-2 m.); same locality, June 1904 

 (Veitch Exped. No. 3016, type of P. prominens Masters); west of 

 Kuan Hsien, near Monkong Ting, valley of Hsao-chin Ho, alt. 2300- 

 2600 m., June 1908 (No. 1500; tree 15-25 m. tall) ; west and near W^n- 

 ch'uan Hsien, alt. 1600-2300 m., November 1908 (No. 1368; tree 12- 

 20 m. tall); near Sung-pan Ting, alt. 2600-3000 m., August 1910 (No. 

 4055; tree 15-20 m. tall, girth 1-2.5 m.). 



This is the common Pine on the mountains of western Szech'uan west of the 

 Red Basin and its altitudinal range is higher than that of any other Chinese 

 Pine. The form on which Masters based his P. 'prominens has dark grey persistent 

 bark and short branches and is always a tree of medium size \nih. a close pyra- 

 midal habit. Pictures of this foi'm will be found under No. 231 of the collection 

 of my photographs and in my Vegetation of Western China, No. 364. 



The form on which P. densata Masters is founded very strongly resembles 

 P. sylvestris Linnaeus in habit and general appearance, having a clean trunk, mas- 

 sive branches forming a rounded or flattened head and pale red bark on the branches 

 and upper part of the trunk, which peels off in thin flakes. West of Fuchien-lu at 

 altitudes of from 300Q-3500 m. in the descent to the Yalung River this tree forms 

 extensive forests. 



In the two varieties the cones are long persistent, and the wood is close-grained, 

 very resinous and durable and is highly esteemed for general building purposes, — 

 it is also used for torches. E. H. W.
