Etymology:

The species is named in honor of the late Mr. Joe Halton, a horticulturist formerly employed at the Marie Selby Botanical Garden in Sarasota, Florida. In his job as a horticulturist at Selby, Joe was responsible for designing Selby Garden’s Display House and for finding plants appropriate for the collection. He was a member of a team of collectors from Sarasota, all associated with the Selby Botanical Gardens, who made explorative trips to Ecuador and Panama, including the trip where this species was collected. Libby Besse described him as her favorite collecting partner and they shared many adventures and hardships together. Unfortunately Joe Halton died in 1989 at his home in Florida.
