first few days it was covered with a large plastic bag and placed in a light conservatory
out of direct sun. By 19 May there was evidence of new leaf growth, the polythene bag
was discarded and the plant was placed outside in a sheltered position. Three weeks
later, further leaf growth indicated that the plant had successfully established itself in the
soil medium. It was then planted out in light loam to which some limestone chippings
had been added. Twelve months later the twig had developed into a bushy form and
bore eleven seeds. It also produced strong new growth from the base. This new growth
