Bermudiana ("Sisyrinchium bermudiana"), the indigenous flower that is ubiquitous in Bermuda in the Spring, has now been realised to be found in one other location, Ireland, where it is restricted to sites around Lough Erne and Lough Melvin in County Fermanagh, and is known as "Feilistrín gorm", or Blue-eyed grass. Early in its history, Bermuda had unusual connections with Ireland. It has been suggested that St. Brendan discovered it during his legendary voyage; a local psychiatric hospital (since renamed) was named after him. In 1616, an incident occurred in which five white settlers arrived in Ireland, having crossed the Atlantic (a distance of around ) in a two-ton boat. By the following year, one of Bermuda's main islands was named after Ireland. By the mid-17th century, Irish prisoners of war and ethnically cleansed civilians were involuntarily shipped to Bermuda, condemned to indentured servitude. This expulsion resulted from the Cromwellian conquest of Ireland. The English government expelled Irish people to other parts of the trans-Atlantic Empire as well. This was meant to pacify Ireland, easing English rule, and to clear land for settlement by English soldiers. The Puritan English government officials also expressed the opinion that they were saving the souls of the Roman Catholic Irish by settling them in Protestant territories where they would inevitably be converted to the true faith. Smaller numbers of Scottish prisoners were also sent to Bermuda following Cromwell's invasion of Scotland.
