I've been looking for references for Hoya compacta. Kew WCSPF references it as unresolved on the Plant List.
Plant List
IPNI notes it as being published in 1990 by C.M. Burton as a cultivated plant.

EOL notes a pressed specimen being collected by C. Burton in Panama.

None of the other Taxon databases I have checked list species
Hoya compacta. The RHS DB notes Hoya carnosa 'Compacta' as a cultivar.

Are all Hoya "Compacta",
Hoya carnosa species? Are they hybrids? Any help appreciated.
