Thank you once again to Earl B. of the USA for sharing another one of his photographs, this time from a vacation to Costa Rica. Much appreciated!
If my identification is correct, and it may not be considering there are over a hundred species of Heliconia as well as a number of cultivars, this is Heliconia stricta. Sometimes commonly known as dwarf Jamaican heliconia, it is not native to Jamaica but rather northern and western South America as well as Brazil. Like many Heliconia species, however, it is cultivated as an ornamental throughout the Caribbean.
To view some of the diversity within the family, visit the Heliconia gallery at Project Amazonas or the Heliconiaceae page at the commercial Montoso Gardens in Puerto Rico (note: this isn’t an endorsement of their commercial services).
