Western Kansu: " Lotani," 1911, TF. Purdom (No. 805); banks of Tow 

 River, 1911, W, Purdom (No. 823). Shensi : Tai-pei-shan, alt. 3000 m., 1910, TF. 

 Purdom (No. 405). Eastern Szech'uan: Chengkou Ting, P. Farges (type). 

 This Silver Fir appears to us quite distinct from A. Fargesii Franchet and in 

 raising it to a species we have drawn up a complete description based on Pur- 

 dom's No. 805, which as far as we can determine from a fragment and photograph 

 of the type received from Paris is identical with Franchet's variety. Unfortu- 

 nately we are without any precise information about this tree, which is char- 

 acterized by its shining red or purplish browTi glabrous branchlets medium- 

 sized symmetrical, scarcely resinous, violet-black cones with shortly cuspidate, 

 obovate-cuneate bracts; and by its ascending, stout, relatively short and broad 

 leaves with a distinct petiole which is yellowish in color. It is most closely allied 

 to A. Faxoniana Rehder & Wilson which is distinguished by its villose branchlets 

 longer and thinner leaves, its exserted long-cuspidate spatulate or cu n eat e-ob long 

 bracts, and by its usually very resinous cones. In transverse section the leaves are 

 seen to be very broad, with median resin-ducts, and a single layer of hypodcrm 

 cells on the ventral side but none on the dorsal side except immediately beneath 

 the midrib. The margins are rounded with several layers of sclerotic tissue. 



Purdom's No. 405 possibly does not belong here. The specimens are without 

 leaves and the cones are immature with exserted bracts, and were probably gathered 

 from a dead branch. Young seedling plants bearing this number and raised from 

 seed collected by Purdom can scarcely be distinguished from A. Fargesii Franchet. 

 For geographical reasons we refer this No. 405 tentatively to A. sutchuenensis 

 Rehder & Wilson rather than to A. Fargesii Franchet, though it may belong to 

 the latter species. 



The specimens referred by Beissner (in Bull. Soc. Bot. Ital. 1901, 358) to A. 

 Mariesii and those referred in his Handb. Nadelholzk. ed. 2, 192 (1906) to A, 

 Veilchii^ which are doubtless the same as mentioned by Masters (in Jour. Linn. 

 Soc. XXVI. 557 [1902]), probably belong either to A. sutchuenensis or possibly to 

 A. Fargesii Franchet but without seeing the specimens it is impossible to decide. 

 It is now believed that the Chinese species of Pinaceae are confined to China and 

 It is highly improbable that either A. MaHesii Masters, or A. Veitchii Lindlcy or 

 any other Japanese Fir or Spruce occurs in China proper.
