This document summarizes efforts to rescue the endangered plant species Cylindrocline lorencei from Mauritius through tissue culture techniques. The species was last observed in the wild in the 1980s and was considered extinct by 1990. In 1990, embryo rescue was used on the last remaining seeds, yielding only 6 plantlets. By the early 2000s, these 3 surviving clones were the only individuals left in botanic gardens. A second rescue effort in the 2010s used tissue culture on sprouting buds from old stems, producing 12 explants that survived without contamination. After over a year of slow propagation, rooted plants were produced. In 2011, one of the rescued plants was returned to its native habitat in Mauritius in
