Dr. Alain Chautems, of the Geneva Botanical Garden, thinks this species is likely to be Sinningia piresiana, although this has not yet been confirmed. The plant produces a caudex-like tuber, and in general habit is similar to S. canescens or S. leucotricha. The flowers have some resemblance to those illustrated in an antique print of Gesneria douglasii.
Alan LaVergne, of the Saint Francis Sinningia Farm, thinks that this plant is definitely Sinningia piresiana. It has the pinkish flowers with dark purple markings on both the inside and outside of the corolla, and the silvery fuzz on the leaves. Hybrids that he has made with this species usually have subdued markings on the outside of the corolla and hairy but not silvery leaves.
This species is very attractive and well worth a grower’s investment of time.
A small plant, exhibited at the 2020 virtual show of the Gesneriad Society, can be seen here.
