Synonyms[1]

Guarianthe aurantiaca is a species of orchid. It is widespread across much of Mexico, south to Costa Rica.[1] The diploid chromosome number of G. aurantiaca has been determined as 2n = 40.[2]

The phananthrenoids orchinol and loroglossol have a phytoalexin effect and reduce the growth of G. aurantiaca seedlings.[3]
