A new identity for cultivated Petrocosmeagrandiflora’Gesneriaceae

Curtis’s Botanical Magazine 2019 36 (2): 134–143.




Petrocosmea thermopuncta, a probable hybrid species from Yunnan, is described and illustrated. Formerly known in cultivation as P. grandiflora, this taxon is named thermopuncta (hotspot) with reference to the dark spot in the corolla tube (Note: It might be mean red but so dark and ‘hot’ that it turns to be purple and black. SMILE!) and its growing in a biodiversity hotspot, (though of uncertain geographical provenance).
