Then I found this "dildo cactus" with an hilarious description. It would be difficult to make up a description with more inuendos (which I have highlighted for your convenience )
DILDO CACTUS - This large tall cactus is common in the bush land of Antigua and Barbuda. As is usual with the commonest plants it has had many economic uses in the past. The small fruits are edible, jams and syrups have been made from them. Sterile water may be found in the stems, which leads to the nibbling by goats. When the flesh is dried and powdered it can be used as a soup. The dried branches, when set alight, burns with sparkles, hence it was once used to celebrate Guy Fawkes Day known as 'Packing Night' (9th & 11th Nov) in Antigua and Barbuda.
The caption under this pic states that this cactus is known as the dildo cactus in the Virgin Islands I GUESS THAT'S HOW THE ISLAND GOT IT'S name
