A new identity for plants cultivated as Petrocosmea ‘minor’Gesneriaceae

Curtis’s Botanical Magazine 2021 vol. 38 (1):115–125

SUMMARY

Plants currently widespread in cultivation under the misapplied name Petrocosmea ‘minor’ have recently been described as P. rotundifolia. The application of the name P. minor is examined resulting in the reinstatement of Petrocosmea henryi from synonymy under P. minor.
