Narrative
Full name as recorded at U.S. National Arboretum: Picrasma quassioides. Source's No. 2 [likely indicating the number of clones represented -SBL]. Two indivduals growing at USNA (31718-H and 31718-J) are female, while the other two (31718-L and 31718-P) are male. [From Alfred J. Fordham of the Arnold Arboretum in the Proceedings of the International Plant Propagators' Society 19: 284-287, Production of Juvenile Shoots from Root Pieces: "In 1967 while visiting Professor Elwyn M. Meader of Rochester, New Hampshire, we viewed two trees of _Picrasma quassioides_, the Korean Butter tree, which had been raised from seeds collected by him near Seoul, Korea. This rare tree was not present in the collection at the Arnold Arboretum so we were anxious to acquire it. His trees had not produced seeds and the question of how it should be propagated arose. _Picrasma_ is a close relative of _Ailanthus_ which propagates by root cuttings so it was decided to try that method. Professor Meader provided root sections which on November 14th were placed horizontally in flats of sandy soil and covered to a depth of one-half inch. By December 28th shoots started to appear and when large enough they were harvested and inserted as cuttings. Further shoots developed and they too were taken. Production of shoots has now continued for two years, and 86 have arisen from eight relatively small root pieces. It is astonishing that food reserves in the roots have been sufficient to support this activity for such a period of time. [...] It should be added that when propagated under mist the cuttings showed leaching and some defoliated. Of these, many produced new leaves and later rooted. Under polyethylene plastic they rooted well." Form received: rooted cutting.
