Some controversy over the accepted name. PlantList shows J. caerulea (L.) Juss. - but IPNI and ARS-GRIN show this as "nom invalid, combination not made". They show J. caerulea (L.) J.St.Hil. as the valid name. The Linnaean Typificaton Project shows the accepted name as J. caerulea (L.) Griseb. (published in Fl. Brit. W.I. (Grisebach) 5: 446. 1862.)
Native to the Caribbean.
