The NPR website has a nice article, plus streamable audio of the radio show, available at: NPR : The Little Coffee Plant that Wouldn't Die, which includes the passage from Last Chance To See which described the story behind the plant Ramosmania rodriguesii, and inspired the article.
[Robert Krulwich] has pieced together the rest of the story, which, very briefly, involves:I enjoyed listening to it Robert, very enlightening!
-- an international rescue mission that rushed two fragile bits of plant to London.
-- a 20-plus-year attempt by some of the most sophisticated botanists in the world to get this plant to create a seed so it could have a future.
-- a daring experiment in 2003 that produced a breakthrough.
-- and, most important, and most dramatically, an unanticipated, unexplainable and utterly mysterious conclusion.
(Well, you should listen to the story. It will make you smile.)
Kew Gardens has a page on the café marron plant.
