Western Szech’uan: Tsai-erh-ti, 30 miles west of Wa-shan, road- 
side, thickets, alt. 1800 m., September 17, 1908 (No. 914, type); Wa- 
shan, moist woods, alt. 1600-2000 m., very rare, September 1908 (No. 
923). 
This remarkably distinct species is perhaps most closely related to M. Camp- 
bellii Hooker & Thomson which has differently shaped, glabrescent leaves and à 
very different fruit with more numerous, smaller, less crowded carpels without 
beaks and smaller seeds. It may also be compared with M. denudata, var. pur- 
purascens Rehder & Wilson, which is a smaller tree with vinous-purple 
rather differently shaped leaves, glabrous or glabrescent below, much smaller and 
more slender fruits with fewer, laxly disposed carpels without beaks. The shape 
and pubescence of the leaves and the peculiarly stout, elongated fruit with con- 
gee — carpels readily distinguish this species from all other members of 
Magnolia Sargentiana grows to a greater size than any other Chinese Magnolia
