Prosthechea-fragrans-2023-04-16 *SITF has determined this plant is Prosthechea chimborazoensis, not Prosthechea fragrans (May 2023).

This finding is based on correspondence received from the Montreal Botanic Gardens. The plant was previously identified as P. chimborazoensis from 1959 to 2008, but changed the name when it was considered synonymous with P. fragrans by Kew's Orchid Checklist; it was not returned to the correct name when Kew segregated the species into two separate taxons. The plant was wild collected in Ecuador by Jose Strobel in 1956 and identified as Epi. chimborazoensis by Garay in 1959. The major distinguishing feature separating the two species are spots on the sepals and petals on P. chimborazoensis and this plant; P. fragrans is whiter and devoid of spots.
