| Bark: | Purple grey; shallow scaly ridges develop (horizontal lines and lenticels). New shots remain woolly white for most of the year. | ||
| Leaf: | Large, long, wide and rounded, 20 cm x 17 cm. Dark green above but white fluffily tomentose beneath. Stalk/midrib 3 mm thick. Minor veins make a lattice between the rather distant main veins. | ||
| Flowers: | In clusters, 8 cm to 10 cm wide. Loose, woolly, flowers of 5 white petals, bowl-shaped around pink-tipped stamens. | ||
| Fruit: | Apple shaped, russet-rosy brown when ripe, about 25 mm, lenticellate and with 2-3 seeds. | ||

| Plant Hunter: | William John Mitchell, curator at Westonbirt Arboretum, Gloucestershire. | ||
| Introduction Date: | Original Westonbirt 17 m specimen, planted in 1938, was raised from seed which may have been collected in Yunnan since it closely resembles plants collected there by Forrest and others. | ||
| Comments: | In winter, still white-backed fallen leaves litter the ground round the tree disconcertingly like discarded picnic plates. | ||
