Pseudotsuga sinensis, Dode.^ 

 Chinese Douglas Fir. 



A large tree in W. China. Young shoots reddish brown at 

 first, becoming grey with age, covered with minute hairs. Buds 

 non-resinous. Leaves pectinate in arrangement, 1-1 1 in. long, 

 notched at the apex ; upper surface furrowed from base to apex, 

 lower surface with a raised midrib and two narrow white bands 

 of stomata. Cones about 2 in. long and 1| in. wide, consisting 

 of about 20 large, thick, woody scales with short, reflexed bracts, 

 the exposed portion of the scale much wider than in P. Forrestii ; 

 bracts shorter than the scales, reflexed near the apex with a long 

 central awn and two short lateral lobes. Seed ^-1 in. long, 

 including the wing. 



A rare species found by Pere Maire on a limestone formation 

 at 8,500 ft. elevation at Che-hai and Tung-chuen. 



We have seen no specimens, but seedlings were raised by M. 

 Chenault at Orleans in 1912, and one of these plants, sent to 

 Leonardslee, Sussex, was 2| ft. high in 1918. 



Pseudotsuga Wilsoniana, Hayata. 



FoRMOSAN Douglas Fir. 



A little-known species recorded only from Mount Morrison, 

 Formosa, at 9,000 ft. altitude. We have not seen specimens, 

 but from the available descriptions it is evidently closely allied 

 to P. sinensis, from which it chiefly differs in its shorter leaves. 

 It is not in cultivation.
