396 WILSON EXPEDITION TO CHINA 
peduncle left behind by the spathoid bract. The flowers in shape and size re- 
semble those of M. parviflora Siebold & Zuccarini, to which species Finet & Gagne- 
pain referred it as a variety. The Japanese plant, however, has yellow-gray bark, 
broadly ovate to obovate glabrescent leaves, which are scarcely ever hairy except on 
the veins, and a long peduncle with no signs of a scar. Magnolia Wilsonii has close 
affinity with M. globosa Hooker & Thomson which has straw-colored bark, broadly 
ovate, much larger leaves, different pubescence and obovate sepals. The closest 
relative of this new species is M. Nicholsoniana Rehder & Wilson, which is dis- 
tinguished by its yellow-gray bark passing to dull purple the second year, by the 
generally elliptic-oblong, sometimes obovate-oblong leaves, commonly cuneate at 
the base, glabrous except on the pubescent midrib and glaucescent below, and by 
the rather smaller fruit with few carpels. Magnolia Wilsonii is quite common in 
the moist woods and thickets to the south-east of Tachien-lu, usually in the form 
of a straggling bush. In late May and early June it is very conspicuous with its 
pure white petals and sepals and bright red stamens and carpels. It is very flori- 
ferous and fragrant and promises to be a welcome addition to the list of cultivated 
species.

This is a very distinct species readily distinguished by its leaves which in shape 
and texture resemble those of M. salicifolia Maximowicz, except that in the latter
