Abstract

AFTER its discovery in the interior of China at latitude 30° N in 1941, Metasequoia glyptostroboides was introduced to Britain in 1948, and has been propagated by cuttings and established in botanical gardens and parks throughout the country. Although there are now specimens up to 16 m high, flowering has been confined to occasional female cones, which in the absence of pollen have not produced viable seeds1. Male cones do not seem to have been recorded here2 although both seedlings and cuttings growing in the Crimea at 45° N have produced them after an interval of 7 yr3. Flowers of both sexes have been induced in Japan by strangulation4 and by treatment with gibberellic acid5–7.
