This species has shiny leaves with a bumpy (bullate) texture. This accounts for the peculiar quality of the photo. Another photo of the species which nicely illustrates its formal and attractive nature, can be seen here. A plant shown at the 2006 Convention of the Gesneriad Society can be seen here. Another plant, also shown at this convention, illustrates the beauty of this species.
Note the visibly hairy leaves, characteristic of many of the Petrocosmea species. As several species are adapted to periods of drought, often when growing on rocks, the hairs may help to reduce transpiration.
Petrocosmea cryptica has had a lot of names having been in cultivation for over 10 years. “The Plantman” magazine, September 2011, “A New Species of Petrocosmea”, Julian Shaw discovers that a gesneriad that has been in cultivation under the wrong name for more than 10 years is a new species”.
