Flowers fragrant, borne in late summer in a terminal inflorescence, each flower 13 in. across, white, soon changing to yellow; they are unisexual, with both sexes on the same inflorescence; calyx-lobes ovate, pointed; styles three. Fruit an ellipsoid capsule 12 to 34 in. long, many-seeded, seeds winged. Bot. Mag., n.s., t. 480.

    Native of China; discovered by Henry in the province of Hupeh about 1889. It did not reach English gardens until 1908, when Wilson sent seeds to the Arnold Arboretum, some of which were distributed in Europe. Some of the young seedlings raised at Kew perished in the severe winter of 1908-9, but others survived. These proved hardy and the species received an Award of Merit when shown from Kew on 30 August 1960. It deserves to be more widely grown for its fragrant flowers, which are borne late in the season – August and September. Wilson observes that the bark in adult trees is grey and deeply furrowed.

    There is a specimen at Caerhays, Cornwall, measuring 49 × 334 (1971).
